[CP-stable] Pub dependencies & widget_preview_scaffold tests relocation (#182317)
Fixes https://github.com/flutter/flutter/issues/182314

This cherry picks in 2 changes to stable
- https://github.com/flutter/flutter/pull/180886
  - The pub roller was busted, and the stable release missed the update
- https://github.com/flutter/flutter/pull/180658
  - Preceded manual pub roll, required to pass analysis with above change.

This is a manual cherry pick, following https://github.com/flutter/flutter/blob/main/docs/releases/Flutter-Cherrypick-Process.md

Around about when we created the release, the pub roller was busted. It is fixed now (https://github.com/flutter/flutter/issues/180503).

Impacted Users: significant
Impact Description: users cannot upgrade to the latest version
Workaround: None
Risk: Not sure, but the pub roll this is cherry picking landed very very close to the stable release being cut. Analysis and flutter doctor all pass.
Test Coverage: For the widget scaffold change, tests are just relocated
Validation steps: https://github.com/dart-lang/test/issues/2570#issue-3684439955

[CP-beta]Send statusBarTouch events via dedicated messages (#181670)
This pull request is created by [automatic cherry pick workflow](https://github.com/flutter/flutter/blob/main/docs/releases/Flutter-Cherrypick-Process.md#automatically-creates-a-cherry-pick-request)
Please fill in the form below, and a flutter domain expert will evaluate this cherry pick request.

### Issue Link:
What is the link to the issue this cherry-pick is addressing?

https://github.com/flutter/flutter/issues/177992
https://github.com/flutter/flutter/issues/175606

### Impact Description:
What is the impact (ex. visual jank on Samsung phones, app crash, cannot ship an iOS app)?
Does it impact development (ex. flutter doctor crashes when Android Studio is installed),
or the shipping of production apps (the app crashes on launch).
This information is for domain experts and release engineers to understand the consequences of saying yes or no to the cherry pick.

The issues listed above impact app users. For instance #177992 prevents the user from interacting with hamburger menus on iPadOS 26.1+ for context, this probably has always been an issue but on iPadOS 26.1 the height of the status bar became taller so it gets in the way of the hamburger menu.

### Changelog Description:
Explain this cherry pick:
* In one line that is accessible to most Flutter developers.
* That describes the state prior to the fix.
* That includes which platforms are impacted.
See [best practices](https://github.com/flutter/flutter/blob/main/docs/releases/Hotfix-Documentation-Best-Practices.md) for examples.

[flutter/177992] on iPadOS 26.1, tapping on the status bar dismisses the current modal route. 

### Workaround:
Is there a workaround for this issue?

Yes. There is a relatively reliable workaround described here: https://github.com/flutter/flutter/issues/175606#issuecomment-3576240885

### Risk:
What is the risk level of this cherry-pick?

  - [-] Low

### Test Coverage:
Are you confident that your fix is well-tested by automated tests?

  - [-] Yes

### Validation Steps:
What are the steps to validate that this fix works?

Following the repro steps in #177992. I've tried the fix myself on master following the steps outlined in the issue and couldn't reproduce the issue.

Generate Flutter framework swift package (#181578)
This PR creates a FlutterFramework swift package with no real content. This is a placeholder so that plugins may add a dependency on the FlutterFramework in their Package.swift before https://github.com/flutter/flutter/pull/178931 lands in stable. See go/swiftpm-flutter-release.

Impacted Users: Flutter iOS with SwiftPM feature flag enabled

Impact Description: Allows plugins to add a dependency on the FlutterFramework in their Package.swift.

Workaround: See Problem 2 alternatives in [go/swiftpm-flutter-release](http://goto.google.com/swiftpm-flutter-release)

Risk: This PR by itself is low risk. It just generates a couple files in an ephemeral directory. It only is actually used if a plugin adds a dependency on it in it's Package.swift. If a plugin does this, it's still low risk since it's basically just an empty Swift package. It's also behind a feature flag (`flutter config --enable-swift-package-manager`), which can be disabled.

Test Coverage: Yes

Validation Steps: 
 - `flutter config --enable-swift-package-manager`
 - `flutter create my_plugin && cd my_plugin/example`
 - Add `FlutterFramework` to Package.swift (see [example](https://github.com/flutter/flutter/blob/master/packages/integration_test/ios/integration_test/Package.swift#L15-L21))
 - `flutter build ios`

[CP-beta]Fixes Typo in codebase (#181354)
This pull request is created by [automatic cherry pick workflow](https://github.com/flutter/flutter/blob/main/docs/releases/Flutter-Cherrypick-Process.md#automatically-creates-a-cherry-pick-request)
Please fill in the form below, and a flutter domain expert will evaluate this cherry pick request.

### Issue Link:
https://github.com/flutter/flutter/issues/181153

### Impact Description:
This PR is to fix a typo in a newly added API (AccessiblityFocusBlockType->AccessibilityFocusBlockType)
The typo was inroduced in this PR  https://github.com/flutter/flutter/pull/175551 which was merged on Nov 3, 2025 and is in 3.39-3.41

What is the impact 
The impact is to fix a small typo by hotfix, so we dont need to deprecate the API and add a new API. 
The risk is small because the API was recently added in Nov, 2025 and it's an API to control accessibility focus. I don't think it's widely used by external developers yet.
Also the typo is not in the previous stable 3.38, so this only needs to be cp to beta. 

### Changelog Description:
Explain this cherry pick:
* In one line that is accessible to most Flutter developers.
* That describes the state prior to the fix.
* That includes which platforms are impacted.
See [best practices](https://github.com/flutter/flutter/blob/main/docs/releases/Hotfix-Documentation-Best-Practices.md) for examples.

[beta] Cherry pick https://github.com/flutter/flutter/pull/181074 (#181367)
This PR cherrypicks https://github.com/flutter/flutter/pull/181074 into beta, which is mostly a revert of https://github.com/flutter/flutter/pull/176711 (except that some docs are left unreverted and a few new tests are added.) This is needed to address a breakage as described in https://github.com/flutter/flutter/issues/180121.

**Impacted Users:** Apps that use `DropdownMenu` or `DropdownMenuFormField` for a nullable class, such as `DropdownMenu<int?>`.

**Impact Description:** Can not compile.

**Workaround:** Yes, through non-trivial changes. For example, the developer can replace  `DropdownMenu<int?>` with `DropdownMenu<Maybe<int>>`, as long as they import `Maybe` or create their own equivalence. 

**Risk:** Low. This PR is basically a revert.

**Test Coverage:** Yes. The widget has high test coverage.

**Validation Steps:** The PR compiles and tests pass.

[beta] Cherry pick https://github.com/flutter/flutter/pull/181269 (#181371)
This PR cherrypicks https://github.com/flutter/flutter/pull/181269 into beta. This is needed to address a breakage.

**Impacted Users:** Apps that directly use `CupertinoSheetTransition `.

**Impact Description:** Can not compile.

**Workaround:** Yes. They need to add `topGap: 0.08` to the constructor.

**Risk:** Low. This PR loosens the API, and reverts the behavior to that before https://github.com/flutter/flutter/pull/171348.

**Test Coverage:** Yes. The widget has high test coverage.

**Validation Steps:** The PR compiles and tests pass. `sheet_test.dart` contains constructors that do not specify `topGap` in the same way as existing apps.

[ Tool ] Fix flake in overall_experience_test.dart (#180655)
The diagnostics string builder responsible for building diagnostics
messages can sometimes wrap lines that are too long. This caused the
expectation for the 'flutter error messages include a DevTools links' to
sometimes be incorrect when run on systems where the absolute file path
of the file referenced in the diagnostic was too long.

This change updates the test expectation to allow for both wrapping and
non-wrapping scenarios to be accepted.

flutter_tools: Auto-generate ExportOptions.plist for manual iOS code signing (#177888)
# flutter_tools: Auto-generate ExportOptions.plist for manual iOS code
signing

## Summary

Enhance `flutter build ipa` to automatically generate a complete
ExportOptions.plist for manual code signing configurations, eliminating
the need for users to create and maintain one manually.

**Fixes:** #177853

## Problem

When using manual code signing (`CODE_SIGN_STYLE=Manual`) with `flutter
build ipa` for Release/Profile builds, the archive succeeds but the
export step fails with:

```
error: exportArchive: "Runner.app" requires a provisioning profile with the Push Notifications and Sign in with Apple features.
```

**Root cause:** Flutter generated an incomplete ExportOptions.plist that
only included `method` and `uploadBitcode`. When using manual signing,
`xcodebuild -exportArchive` requires:
- `teamID` (from project's `DEVELOPMENT_TEAM`)
- `signingStyle=manual`
- `provisioningProfiles` (mapping bundle ID to provisioning profile
UUID)

Without these, Xcode cannot resolve the provisioning profile for export,
even if the profile is correctly configured and contains the required
entitlements.

## Solution

Enhanced `_createExportPlist()` in `BuildIOSArchiveCommand` to
automatically generate a complete ExportOptions.plist when:
1. `CODE_SIGN_STYLE=Manual` is detected for the main app target
2. Build mode is Release or Profile (production builds only)
3. A valid provisioning profile can be located and parsed

The generated plist includes:
- `method` (app-store, ad-hoc, enterprise, etc. - respects user's
`--export-method` flag)
- `teamID` (from `DEVELOPMENT_TEAM` build setting)
- `signingStyle=manual`
- `provisioningProfiles` mapping main app bundle ID to provisioning
profile UUID

**Fallback behavior:**
- If profile lookup fails: silently fall back to simple plist (no
regression)
- For Automatic signing: unchanged behavior
- For Debug builds: unchanged behavior (not App Store export)
- For multi-target apps (extensions): falls back to simple plist today
(see TODO below)

## Changes

### Core Implementation
- Added `ProfileData` class to encapsulate provisioning profile info
(UUID and name)
- Refactored profile handling into reusable static methods for
testability
- Enhanced `_createExportPlist()` with manual signing detection and
profile lookup
- Added `_findProvisioningProfileUuid()` to locate provisioning profiles
by specifier
- Added `_parseProvisioningProfileInfo()` to decode provisioning profile
data once
- Added comprehensive trace logging for debugging

### Testing
- Created `build_ipa_export_plist_test.dart` with 7 unit tests covering:
  - Manual signing with profile found → enhanced plist generated ✓
  - Automatic signing → simple plist (unchanged behavior) ✓
  - Debug builds → simple plist (unchanged behavior) ✓
  - Different export methods → respected in generated plist ✓
  - Profile lookup failures → fallback to simple plist ✓
  - Null codeSignStyle → handled gracefully ✓
- All existing flutter_tools tests continue to pass

## Documentation

Added extensive inline comments explaining:
- Enhancement conditions and fallback behavior
- Provisioning profile search strategy and error handling
- Performance and security considerations
- Future enhancements (multi-target support)

## Safety & Scope

### What This Fixes
-  Manual signing export failures for apps with Push Notifications /
Sign in with Apple
-  Auto-generates correct plist for **any** entitlements covered by
provisioning profile
-  Unblocks users from manual `--export-options-plist` workaround
-  Improves iOS build UX for enterprise teams doing manual signing

### What This Does NOT Change
-  Automatic signing behavior (unchanged)
-  Debug builds (unchanged)
-  CLI interface (no new flags)
-  Ad-hoc / enterprise distributions (unchanged if not using manual
signing)

### Known Limitations (Future Enhancements)
- Currently only supports single-target apps (main app bundle ID only)
- TODO: Multi-target apps with extensions (notification service,
widgets, watch, etc.) - each extension target bundle ID may need
separate entry in provisioningProfiles dict
- TODO: Support for multiple provisioning profiles if app uses multiple
signing identities

## Pre-merge Checklist

- [x] I have signed the CLA
- [x] I read the Contributor Guide and Tree Hygiene docs
- [x] I linked the issue this fixes (#177853) and explained the failure
scenario
- [x] I added documentation and trace logs so developers understand what
changed
- [x] I added comprehensive unit tests for the new behavior
- [x] All existing and new tests pass locally (`flutter test
packages/flutter_tools`)
- [x] Code passes linting (`dart analyze`)

## Safety Notes

- [x] This code only runs for manual code signing in `flutter build ipa`
for Release/Profile builds
- [x] Debug builds and automatic signing behavior are completely
unchanged
- [x] If no provisioning profile UUID is found, we silently fall back to
the old exportOptions.plist logic instead of failing
- [x] Added trace-level logging explaining success/fallback scenarios
for debugging
- [x] No breaking changes - existing workarounds continue to work
- [x] Minimal blast radius - only affects manual signing export path

## Verification

Users can verify the fix by:
1. Creating an iOS app with `CODE_SIGN_STYLE=Manual`, `DEVELOPMENT_TEAM`
set, and Push Notifications entitlements
2. Running `flutter build ipa --release --verbose`
3. Confirming the trace log shows "Generated ExportOptions.plist with
teamID, signingStyle=manual, and provisioningProfiles"
4. Verifying the IPA is successfully created without needing
`--export-options-plist`

Do not dispose CupertinoSheetTransition animation on update and throw ticker error (#180609)
<!--

Fixes #179337 by moving the disposal of an animation controller outside
of the didUpdate method flow. It was unnecessary to rebuild this
controller on update, and was originally put there to follow the pattern
of the other animations. However, unlike the other animations, this one
is not chained to animations from outside of the transition's place in
the tree, and was throwing exceptions from the ticker mixin in some
cases.

Add drag handle to CupertinoSheet (#179962)
Fixes #179358.

Adds the option to add a native styled drag handle to the top of a
Cupertino sheet through the `showDragHandle` property. By default this
is false, the same way it is for the native SwiftUI sheet.

Styling for the handle is based off of native versions of the handle,
and Apple's Figma files.

Fix Drawer.child docstring to say ListView instead of SliverList (#180326)
## Description

The docstring says "Typically a [SliverList]" but the class example uses
`ListView`.

`SliverList` is used inside `CustomScrollView`, not as a direct child of
`Drawer`.

Run hook_user_defines and link_hook integration tests on CI (#180622)
Fixes https://github.com/flutter/flutter/issues/180575.

As per the
[readme](https://github.com/flutter/flutter/blob/master/dev/integration_tests/README.md#:~:text=Adding%20code%20to%20this%20directory%20will%20not%20automatically%20cause%20it%20to%20be%20run%20by%20any%20already%20existing%20ci%20tooling.),
tests in dev/integration_tests are not automatically run on CI:

> Adding code to this directory will not automatically cause it to be
run by any already existing ci tooling.

This PR fixes the problem by running the `hook_user_defines` and
`link_hook` integration tests as part of the tools integration test
shard.

One of the tests actually broke while it wasn't running on CI. This is
fixed by removing it from the workspace to ensure the local user-defines
in its pubspec are applied.

Fix division by zero in RenderTable intrinsic size methods (#178217)
## Description

This PR fixes a division by zero crash in `RenderTable` when intrinsic
size methods are called on empty tables (0 rows × 0 columns) with
non-zero constraints.

### The Problem

When `RenderTable` has 0 columns and intrinsic size methods
(`computeMinIntrinsicHeight`, `computeMaxIntrinsicHeight`,
`computeMinIntrinsicWidth`, `computeMaxIntrinsicWidth`) are called with
non-zero width constraints, the code calls `_computeColumnWidths()`
without checking if the table is empty. This leads to division by zero
at line 1140:

```dart
final double delta = (minWidthConstraint - tableWidth) / columns;
// When columns = 0, this crashes with division by zero
```

### The Solution

Added early return checks `if (rows * columns == 0) return 0.0;` to all
four intrinsic size methods, matching the pattern already used by other
methods that call `_computeColumnWidths()`:

- `computeDryBaseline` (line 1242) - already has the check
- `computeDryLayout` (line 1274) - already has the check
- `performLayout` (line 1318) - already has the check
- `paint` (line 1461) - already has the check

Now all four intrinsic methods are consistent with the rest of the
codebase.

### Testing

Added comprehensive test coverage (`Empty table intrinsic dimensions
should not crash`) that:
- Creates an empty table (0×0)
- Calls all four intrinsic size methods with various constraints
- Verifies they return 0.0 without crashing

### Changes Made

**packages/flutter/lib/src/rendering/table.dart:**
- Added empty table check to `computeMinIntrinsicWidth` (line 963-965)
- Added empty table check to `computeMaxIntrinsicWidth` (line 978-980)
- Added empty table check to `computeMinIntrinsicHeight` (line 995-997)
- Added empty table check to `computeMaxIntrinsicHeight` (line
1016-1019)

**packages/flutter/test/rendering/table_test.dart:**
- Added test case `Empty table intrinsic dimensions should not crash`
- Tests all four intrinsic methods with both finite and infinite
constraints

## Related Issues

This fix addresses a potential crash when using `RenderTable` with
intrinsic sizing widgets (like `IntrinsicHeight`, `IntrinsicWidth`) on
empty tables.

Unpin DDS (#180571)
Fly-by clean-up: My understanding from the
[changelog](https://pub.dev/packages/dds/changelog) is that the change
causing the bug in 5.0.4 has been reverted in 5.0.5. Therefore, the pin
should be no longer necessary? Unpinning to find out...

> 5.0.5 
[DAP] The change in DDS 5.0.4 to individually add/remove breakpoints has
been reverted and may be restored in a future version.
>
>5.0.4 
[DAP] Breakpoints are now added/removed individually instead of all
being cleared and re-added during a setBreakpoints request. This
improves performance and can avoid breakpoints flickering between
unresolved/resolved when adding new breakpoints in the same file.

Fix DropdownMenuEntry.style not resolved when entry is highlighted (#178873)
## Description

This PR adds logic to resolve `DropdownMenuEntry.style` properties with
the correct `WidgetState` when an item is highlighted.

When `MenuItemButton` are highlighted the focused state is not added
automatically because the focus does not move to the items (it stays on
the `TextField` in order to let the user enters text to filter the items
list). This PR sets the `MenuItemButton.statesController` with a forced
focused state to let `MenuItemButton` know that the focused state should
be use to resolve the properties.

## Related Issue

## Add --web-define option for runtime variable injection in Flutter web
templates

This PR adds support for injecting environment-specific variables into
Flutter web templates during development and build processes through a
new `--web-define` command-line option.

### What this changes

**Before**: Developers had to manually edit HTML templates or use
build-time workarounds to inject environment-specific values (API URLs,
feature flags, etc.) into Flutter web applications.

**After**: Developers can now use `--web-define KEY=VALUE` to inject
variables directly into web templates using `{{VARIABLE_NAME}}`
placeholders.

### Key features

- **Template variable substitution**: Support for `{{VARIABLE_NAME}}`
placeholders in `index.html` and `flutter_bootstrap.js`
- **Runtime validation**: Throws clear errors when required variables
are missing with helpful suggestions
- **Command-line integration**: Works with both `flutter run` and
`flutter build web` commands
- **Multiple variable support**: Can define multiple variables in a
single command
- **Built-in variable protection**: Ignores Flutter's built-in template
variables during validation

### Usage examples

```bash
# Development with API configuration
flutter run -d chrome --web-define=API_URL=https://dev-api.example.com --web-define=DEBUG_MODE=true

# Production build with environment variables
flutter build web --web-define=API_URL=https://api.example.com --web-define=ANALYTICS_ID=GA-123456 --web-define=DEBUG_MODE=false

# Multiple environments
flutter run -d chrome --web-define=ENV=staging --web-define=FEATURE_X=enabled
```

### Template usage

In your `web/index.html`:
```html
<script>
  window.config = {
    apiUrl: '{{API_URL}}',
    environment: '{{ENV}}',
    debugMode: {{DEBUG_MODE}}
  };
</script>
```

### Error handling

If a variable is missing, the tool provides clear feedback:
```
Missing web-define variable: API_URL

Please provide the missing variable using:
flutter run --web-define=API_URL=VALUE
or
flutter build web --web-define=API_URL=VALUE
```

## Issues fixed

Fixes https://github.com/flutter/flutter/issues/127853

## Additional Usage Examples

### Environment-Specific Configurations (Flavors)
```bash
# Development

<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());
  gtag('config', '{{GA_ID}}');
</script>
```

### Feature Flags

```json
{
  "scripts": {
    "dev": "flutter run -d chrome --web-define=ENV=dev --web-define=API_URL=http://localhost:3000",
    "prod": "flutter build web --web-define=ENV=prod --web-define=API_URL=https://api.example.com"
  }
}
```

### Important Notes
- **Security**: Never expose secrets via `--web-define` (client-side
only)

Restore CLI precedence for web headers and HTTPS over web_dev_config.yaml (#179639)
This PR restores the correct precedence behavior for web development
server configuration. Since Flutter 3.38, CLI arguments were being
ignored when `web_dev_config.yaml` was present — specifically for HTTPS
and headers.

According to the design and documentation, the precedence should be:

1. Command-line arguments (highest priority)
2. `web_dev_config.yaml`
3. Built-in defaults (lowest priority)

## Root Cause

The regression affected:

* **HTTP headers** — merge order was reversed, causing file config to
override CLI
* **HTTPS config** — CLI TLS arguments were ignored under certain
conditions

Note:
`--web-port` and `--web-hostname` were already working correctly due to
the `host ?? this.host` and `port ?? this.port` pattern.
The observed issue was due to headers + HTTPS only.

## Changes Made

* Fixed header merge order so CLI takes precedence
* Corrected HTTPS config resolution and precedence logic
* Unified logic across `run` and `drive` commands
* Simplified HTTPS handling using `HttpsConfig.parse()`
* Added tests for CLI precedence behavior

## Before (broken)

```
flutter run -d chrome --web-tls-cert-path cert.pem
```

 CLI TLS args ignored when config file existed
 headers overridden by file config

## After (fixed)

```
flutter run -d chrome --web-tls-cert-path cert.pem
```

 CLI TLS args respected
 headers override config as expected

## Tests

* Added tests verifying CLI takes precedence
* All existing and new tests pass
* No breaking changes introduced

## Fixes

Fixes: #179014

Enable misc leak tracking (#176992)
This PR adds a new subshard that runs leak tracking tests on
flutter/misc.

This is used to address a problem faced by PR
https://github.com/flutter/flutter/pull/176519, which fixes a leak in
`WidgetTester` but is unable to write a unit test.

I'm not certain this is the best approach so I'm open to other
suggestions.

[hooks] Don't require NDK for Android targets (#180594)
When targeting Android, don't fail in Flutter tools if the NDK is not
installed. Instead, pass a `null` c compiler config to the hooks. The
hooks can then decide to fail if they need the NDK. If no hook happened
to require the NDK, Flutter for Android apps can be built without the
NDK installed.

Bug: https://github.com/flutter/flutter/issues/180163

Fix/ios share context menu (#176199)
This PR fixes https://github.com/flutter/flutter/issues/173491 by adding
the missing 'Share' option to the default iOS SystemContextMenu when
shareEnabled is true.

Changes:

Added IOSSystemContextMenuItemShare to getDefaultItems in
system_context_menu.dart.
Added a widget test to ensure Share is present in the default items for
non-empty selections on iOS.
Rationale:
This aligns Flutter's default iOS text selection context menu with
native iOS behavior, ensuring users see the expected 'Share' option when
selecting text.

Demo:
Video showing Share option in iOS context menu:

Add DropdownMenuFormField.errorBuilder (#179345)
## Description

This PR adds the `DropdownMenuFormField.errorBuilder` property which
makes it possible to customize the widget used to display the error
message.

This is a follow-up to https://github.com/flutter/flutter/pull/162255
which added the `errorBuilder` property to other form fields.

## Related Issue

Fixes [DropdownMenuFormField is missing an errorBuilder
property](https://github.com/flutter/flutter/issues/172416)

## Tests

Updates 5 tests.
Adds 1 test.

Don't embed unreferenced assets (#179251)
When a Flutter app depends on a package using hooks to add code assets,
those get built to `build/native_assets/$platform`, where `$platform` is
something like `ios` or `macos`. Crucially, there's no difference
between simulator or release builds here, all native assets for a
platform end up in that directory.

To embed those frameworks with the app, the "sign and embed" stage of an
XCode build invokes `xcode_backend.dart`, which then copies all
frameworks from `build/native_assets/$targetPlatform` into
`$build/Runner.app/Frameworks`. This is a problem when a developer runs
a simulator build followed by a release build without clearing the build
folder in between, since both assets would be in
`build/native_assets/ios` at that point.

This fixes the issue by:

1. Reading the `native_assets.json` file emitted by the main build.
2. Only copying frameworks referenced in that file.

This still needs an integration test.

Closes https://github.com/flutter/flutter/issues/178602.

[ Widget Preview ] Add UUID to registered DTD streams and services (#180140)
DTD only supports a single instance of a registered service with a given
name. For widget preview development, we sometimes want to use a DTD
instance that's attached to an IDE to test IDE integration. However,
IDEs frequently spawn their own widget preview instances which register
services with DTD. In the case where `flutter widget-preview start
--dtd-url=<dtd-url>` is run and `dtd-url` points to a DTD instance with
another widget preview service running, the process simply crashes.

This change adds a unique identifier to the widget preview DTD service
and stream names that allows for each `flutter widget-preview start`
instance to register its own unique widget preview DTD services, even if
other widget preview instances are using the same DTD instance.

Some cleanup of cross library test imports (#177029)
There is a lot of cross-library importing in the framework unit tests
that I'd like to clean up, see the design doc for more:
https://docs.google.com/document/d/1UHxALQqCbmgjnM1RNV9xE2pK3IGyx-UktGX1D7hYCjs/edit?tab=t.0

This PR cleans up a few obvious instances and adds TODOs for others. I
created this while doing an investigation for the design doc linked
above. I hope that we'll be able to follow up with fixes for all of the
problematic tests (tracked in the issue below).

Improve Container color/decoration error message clarity (#178823)
## Description

This PR improves the clarity of the error message shown when developers
provide both `color` and `decoration` parameters to a `Container`
widget.

### Problem

The previous assertion message was confusing and contradictory:
```
Cannot provide both a color and a decoration
To provide both, use "decoration: BoxDecoration(color: color)".
```

This message stated "Cannot provide **both**" but then suggested "To
provide **both**, use...", which confused developers about the actual
requirement. The suggestion appeared to offer a workaround to use both
parameters together, when in fact it was explaining how to migrate from
using `color` to using `decoration` exclusively.

### Solution

Updated the assertion message to clearly explain:
- The `color` parameter is a shorthand for `decoration:
BoxDecoration(color: color)`
- Developers should use **either** `color` OR `decoration`, not both
- To use both a color and other decoration properties (like borders,
shadows, etc.), set the color within the `BoxDecoration` instead

**New message:**
```
Cannot provide both a color and a decoration.
The color argument is just a shorthand for "decoration: BoxDecoration(color: color)".
To use both a color and other decoration properties, set the color in the BoxDecoration instead.
```

[Framework] iOS style blurring and ImageFilterConfig (#175473)
This PR adds the framework support for a new iOS-style blur. The new
style, which I call "bounded blur", works by adding parameters to the
blur filter that specify the bounds for the region that the filter
sources pixels from.

As discussed in design doc
[flutter.dev/go/ios-style-blur-support](http://flutter.dev/go/ios-style-blur-support),
it's impossible to pass layout information to filters with the current
`ImageFilter` design. Therefore this PR creates a new class
`ImageFilterConfig`.

This PR also applies bounded blur to `CupertinoPopupSurface`. The
following images show the different looks of a dialog in front of
background with abrupt color changes just outside of the border. Notice
how the abrupt color changes no longer bleed in.

<img width="639" height="411" alt="image"
src="https://github.com/user-attachments/assets/4ceb9620-1056-45c3-b5fa-2ed16d90aace"
/>

<img width="639" height="411" alt="image"
src="https://github.com/user-attachments/assets/abe564f7-ea60-4d07-ad58-063c0e3794a5"
/>

This feature continues to matter for iOS 26, since the liquid glass
design also heavily features blurring.

### API changes

* `BackdropFilter`: Add `filterConfig`
* `RenderBackdropFilter`: Add `filterConfig`. Deprecate `filter`.
* `ImageFilter`: Add `debugShortDescription` (previously private
property `_shortDescription`)

### Demo

The following video compares the effect of a bounded blur and an
unbounded blur.

Add support for Shift-Delete, Ctrl-Insert and Shift-Insert (#178561)
This PR adds `SingleActivator` mappings for IBM CUA style clipboard
accessors, with which Shift-Delete, Ctrl-Insert and Shift-Insert are
equivalent to ^X ^C ^V. These mappings are natively supported on Windows
and Linux (but not OS X).

~Not sure what to do about:~
- ~Documentation: Are ^X ^C ^V already documented?~
- ~Tests: Are there existing tests for ^X ^C ^V already? Is it possible
to mock out the clipboard so that a test of this functionality doesn't
hit the actual system clipboard?~
- ~OS X: Is it a problem that, with this change, Flutter will accept
these additional shortcuts even though they aren't a part of the
platform paradigm?~

UPDATE:
I'm not aware of existing documentation of clipboard shortcuts.

I have added tests, both of the existing ^X ^C ^V and of the IBM CUA
style mappings added by this PR, and in the current iteration the
changes do not add IBM CUA style mappings on OS X.

Fixes: #178483
