Add TabBar API example for scroll notification integration (#180728) 
- A part of: https://github.com/flutter/flutter/issues/123965
- Description: This PR adds an example that came from
https://github.com/flutter/flutter/issues/123965#issuecomment-3722456594
as a workaround. I bring it into an API example so that users can find
it easier.
The example showcases how to apply custom behavior based on the scroll
in TabBar. It utilizes scroll notifications (ScrollMetricsNotification
and ScrollNotification) within NotificationListener callback to monitor
the scroll offset, allowing for interface customization based on the
obtained offset.

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`.

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.

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

Fixes [DropdownMenuEntry style's text style is not resolving with
states](https://github.com/flutter/flutter/issues/177363)

## Tests

- Adds 1 tests.

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:

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.)

Update the Material IconAlignment sample (#179159) 
Migrates the samples to remove references to the deprecated
`ButtonStyleButton.iconAlignment`.

The sample doesn't actually use `ButtonStyleButton.iconAlignment`
directly, but it does refer to it in docs.

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
