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

docs: clarify dropdown menu text clearing (#179676) 
<!--
Thanks for filing a pull request!
Reviewers are typically assigned within a week of filing a request.
To learn more about code review, see our documentation on Tree Hygiene:
https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md
-->

The documentation for `DropdownMenu`'s `controller` and
`initialSelection` properties has been updated. It now explicitly states
that clearing the text field requires using a `TextEditingController`'s
`clear()` method, and that setting `initialSelection` to null will not
clear the text. A code snippet demonstrating how to clear the text field
has also been added.

Fix for: #177599

Remove an obsolete TODO in DataTable (#180033) 
When the `InkWell` was added, it was used only for a gesture callback,
and at that time the InkWell should only be added when the gesture
callback was needed. Due to an issue, we couldn't swap out the child
widget dynamically.

Even though that the issue has been fixed, the `InkWell` is considered
mandatory since it is now used by two more properties. (Theoretically we
can check if any of the 3 properties is needed to add this `InkWell`,
but I think that's too much.)

This PR adds extra properties to `CheckboxListTile`, `SwitchListTile`
and `RadioListTile`. These properties are already implemented for the
`ListTile` and passed through from `CheckboxListTile`, `SwitchListTile`
and `RadioListTile` to the underlying `ListTile`.

The following properties are added:
    - `horizontalTitleGap`
    - `minVerticalPadding`
    - `minLeadingWidth`
    - `minTileHeight`

Fixes #83898 and builds on #154417 and #83902

Add Adwaita Sans as a font fallback on Linux (#179144) 
Gnome 48 (from March 2025) switched its default font from `Cantarell` to
`Adwaita Sans`:
https://blogs.gnome.org/monster/introducing-adwaita-fonts/.

This PR adds `Adwaita Sans` to the Linux font fallbacks list: `Adwaita
Sans` will be used instead of `Cantarell` if available.

Adwaita Sans is a slightly tweaked version of Inter, and therefore fits
in with `Roboto` and the rest of the Linux font stack.

- Closes https://github.com/flutter/flutter/issues/179141

[ios][pv] accept/reject gesture based on hitTest (with new widget API) (#179659) 
This is a follow up PR to [this original
PR](https://github.com/flutter/flutter/pull/177859).

The difference is the API - the original PR chooses Option 1 [in the
design
doc](https://docs.google.com/document/d/1ag4drAdJsR7y-rQZkqJWc6tOQ4qCbflQSGyoxsSC6MM/edit?tab=t.0),
while this PR chooses Option 3.

## Usage

To directly use flutter API, just pass in the policy when creating
UiKitView widget.

```
UiKitView(
  ...
  gestureBlockingPolicy: UiKitViewGestureBlockingPolicy)
  ...
)
```

For plugins, we need to update plugins to use this new API. 

```
WebView(
  ...
  gestureBlockingPolicy: UiKitViewGestureBlockingPolicy
) {
  return UiKitView(
    ..
    gestureBlockingPolicy: gestureBlockingPolicy
  )
}
```
For more information, refer to [the old
PR](https://github.com/flutter/flutter/pull/177859).

This change reverts the following previous change:
The `flutter_analyzer_plugin` implements rules previously enforced by
the `dev/bots/analyze.dart` check run on the CI, allowing for earlier
detection of custom lint violations before a change is uploaded for
review.

Currently, the plugin implements the following rules:

  - avoid_future_catch_error
  - no_double_clamp
  - no_stopwatches
  - protect_public_state_subtypes
  - render_box_intrinsics

Reland: Add framework-side hitTestBehavior support to Semantics (#178817) (#179352) 
This is a reland of #178817, which was reverted in #179100 due to test
failures.

The original PR introduced `hitTestBehavior` to the semantics framework
but incorrectly applied `opaque` behavior to `ModalRoute`, which blocked
platform views from receiving pointer events.

Instead of making the entire modal opaque, we:
1. Keep `ModalRoute` without explicit `hitTestBehavior` (defaults to
`defer`)
2. Make only the dialog/sheet content opaque (blocks clicks to barrier)
3. Platform views remain clickable because they're outside the opaque
content boundary

Fixes #149001
Original PR: #177570
Revert: #178744
