Add semanticIndexOffset argument to SliverList.builder, SliverGrid.builder, and SliverFixedExtentList.builder (#174856) 
Issue: #173019 

This pull request adds support for the `semanticIndexOffset` parameter
to the `SliverList.builder`, `SliverFixedExtentList.builder`, and
`SliverGrid.builder` constructors in Flutter. This allows developers to
offset the starting semantic index for items in these slivers, which is
important for accessibility scenarios (such as when combining multiple
slivers). The changes are thoroughly tested with new widget tests to
ensure correct behavior.

**Accessibility improvements:**

* Added `semanticIndexOffset` parameter to the constructors of
`SliverList.builder`, `SliverFixedExtentList.builder`, and
`SliverGrid.builder`, and ensured it is passed to the underlying
`SliverChildBuilderDelegate`. This allows customization of the starting
semantic index for sliver children.

**Testing:**

* Added a new test for `SliverList.builder` to verify that the
`semanticIndexOffset` is respected in the generated semantics tree.

Update transformHitTests documentation for clarity (#174286) 
## Description 📝

This PR updates the documentation for the transformHitTests parameter in
the Transform widget to resolve ambiguity in the API documentation that
has caused hit testing issues for developers.

The current documentation simply states "Whether to apply the
transformation when performing hit tests" which is ambiguous. As seen in
issues like #27587, developers expect transformed widgets to receive
touch events across their entire visual area, but hits only register
within the parent's original bounds.

**The core issue**:  The documentation lacks clarity on:
❌ Hit test coordinate system transformation vs. hit test bounds
expansion
🔄 Parent widget bounds as the constraint for hit test registration
⚠️ The distinction between visual rendering bounds and interactive
bounds

### Before (Current Documentation) 

*Current documentation is vague: "Whether to apply the transformation
when performing hit tests"*

<img width="1887" height="483" alt="Screenshot 2025-08-22 214745"
src="https://github.com/user-attachments/assets/24569be5-8dbe-4a02-8851-1546b8ac109e"
/>

### After (Improved Documentation) 
<img width="1091" height="293" alt="Screenshot 2025-08-22 214808"
src="https://github.com/user-attachments/assets/f8504134-eba7-43ea-a71f-d9a8740ff295"
/>

*New documentation clearly explains behavior, limitations, and
solutions*

**Changes made:** ✅
- 🔧 Clarified that `transformHitTests` transforms registered hits into
the child's resulting coordinate system
- 🚨 Explicitly documented the critical limitation: only hits within
parent bounds can be registered
- 📚 Explained the behavior difference between `true` and `false`
settings with concrete examples of transformation types
- 💡 Added guidance for common workarounds: expanding parent bounds or
using Overlay for out-of-bounds elements

## Issues Fixed 🐛

Fixes #78120

**Related issues that motivated this change:** 🔗
- #27587 - Developers confused why GestureDetector doesn't respond after
Transform
- Multiple developers reported spending significant time debugging this
behavior
- Common misconception that visual transformation expands the hit test
area

**Note**: This PR is test-exempt as it only updates documentation
comments without changing any functionality.

[Gradle 9] Removed minSdkVersion and only use minSdk (#173892) 
Support for `minSdkVersion` is completely dropped in Gradle 9, and we
should only use `minSdk`. We also included an AGP version checker to
ensure builds did not crash when getting the minimum sdk version. Since
our minimum AGP version is now 8.3, we can remove agp version check.

[ Widget Preview ] Improve --machine output (#175003) 
This change adds the following events:

- `widget_preview.initializing`: sent immediately after the widget
previewer starts. This event includes the PID of the process starting
the widget previewer for use by tooling to explicitly kill the tool
process.
- `widget_preview.logMessage`: sent for calls to `Logger` methods when
in machine mode. This follows the same format as `daemon.logMessage`.

This change also fixes and improves testing of
`WidgetPreviewMachineAwareLogger` in `widget_preview_machine_test.dart`
as the existing test validator did not cause tests to fail correctly.

[web] Reuse chrome instance to run all flutter tests (#174957) 
Web test shards take a significant time to run in CI compared to their
VM counterparts. One theory is that launching and shutting down Chrome
repeatedly is a major part of the slowness.

This PR makes `flutter test --platform=chrome` reuse the same Chrome
instance for all test files instead of launching a new one for each test
file.

At first glance, it may seem like we aren't shutting down Chrome
anymore, but we actually do in `closeEphemeral` and `close` methods.

Thanks @eyebrowsoffire for the idea!

[ Widget Preview] Add group property to Preview (#174849) 
This change adds support for creating groups of widget previews.
Previews with the same `group` parameter will be grouped together in a
collapsable tile in widget previewer. Previews without a provided
`group` will be placed in the `Default` group.

This change also slightly reworks the UI to make individual previews
more easily distinguishable from preview groups, moves the controls for
the previewer to the bottom of the preview window, and adds a divider
between the preview name and preview content if a name is provided.

Fixes https://github.com/flutter/flutter/issues/173871

Fix expanded DropdownMenu panel is shorter than text field (#174443) 
## Description

This PR fixes DropdownMenu menu panel being shorter than the TextField
when it expands to full-screen width.

## Before

The menu panel is shorter than the text field:

<img width="297" height="130" alt="image"
src="https://github.com/user-attachments/assets/db42bd01-94d8-47fb-9331-ebd78111b931"
/>

## After

The menu panel expands as close as possible to the edge similarly to the
text field.

<img width="297" height="130" alt="image"
src="https://github.com/user-attachments/assets/b7d8f2aa-a668-439a-8195-9b9ce48dba6b"
/>


## Code sample

<details><summary>Code sample for recordings</summary>

```dart
import 'package:flutter/material.dart';

void main() {
  runApp(const DropdownMenuExample());
}

class DropdownMenuExample extends StatefulWidget {
  const DropdownMenuExample({super.key});

  @override
  State<DropdownMenuExample> createState() => _DropdownMenuExampleState();
}

class _DropdownMenuExampleState extends State<DropdownMenuExample> {
  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        body: DropdownMenu<int>(
          expandedInsets: EdgeInsets.zero,
          dropdownMenuEntries: <DropdownMenuEntry<int>>[
            DropdownMenuEntry<int>(value: 0, label: 'Flutter'),
          ],
        ),
      ),
    );
  }
}


``` 
</details> 

## Implementation details

MenuAnchor automatically adds a default padding, see
2c21273bfd/packages/flutter/lib/src/material/menu_anchor.dart (L81-L82)

This PR add a property to menu anchor to expose the view padding.
DropdownMenu sets this padding to EdgeInsets.zero to opt-out from the
default 8 padding.


## Related Issue

Fixes [DropdownMenu children is shorter than the TextField when it
expands to full-screen
width](https://github.com/flutter/flutter/issues/172680)

## Tests

Adds 2 tests.

Add data assets (#174685) 
Refiling of #169273 (reverted in
https://github.com/flutter/flutter/pull/170034), which is a refiling of
#164094, which itself is a rebase of #159675.

This PR adds bundling support for the experimental dart data asset
feature: Dart packages with hooks can now emit data assets which the
flutter tool will bundle.

It relies on flutter's existing asset bundling mechanism (e.g. entries
in AssetManifest.json, DevFS syncing in reload/restart, ...).

The support is added under an experimental flag (similar to the existing
native assets experimental flag).

Also, kNativeAssets is removed to also bundle data assets on flutter
build bundle.

The chrome sandbox is disabled as per #165664.

[ Widget Preview ] Respond to IDE navigation events and show previews from the currently focused script (#174466) 
This change allows for the widget previewer to react to
`activeLocationChanged` events sent over the `Editor` DTD service to
automatically filter the set of visible previews based on the currently
selected file in the IDE. This functionality can be turned on or off
depending on whether or not the developer wants to see all previews in
the project at once.

This change also includes some minor refactoring and UI changes to move
the widget preview environment controls to a reserved area at the bottom
of the preview window.

**Demo:**

Add SliverGrid.list convenience constructor (#173925) 
This PR adds a new `SliverGrid.list` convenience constructor that
accepts a `List<Widget> children` parameter, providing a cleaner API
compared to manually creating `SliverChildListDelegate`.

## What was added

The constructor uses `SliverChildListDelegate` internally and follows
the same pattern as existing convenience constructors like
`SliverGrid.count` and `SliverGrid.extent`. This addresses the use case
where developers want to create sliver grids with predefined widget
lists without the verbosity of manually constructing the delegate.

## Before/After comparison

**Before:**
```dart
SliverGrid(
  gridDelegate: gridDelegate,
  delegate: SliverChildListDelegate([widget1, widget2, widget3]),
)
```

**After:**
```dart
SliverGrid.list(
  gridDelegate: gridDelegate,
  children: [widget1, widget2, widget3],
)
```

## Implementation details

- Added `SliverGrid.list` constructor in
`packages/flutter/lib/src/widgets/sliver.dart`
- Constructor accepts `List<Widget> children` and all necessary delegate
configuration parameters
- Uses `SliverChildListDelegate` internally for consistent behavior
- Added comprehensive test coverage in
`packages/flutter/test/widgets/slivers_test.dart`

## Issue addressed

Fixes: #173018

Remove build configuration mismatch warning (#174715) 
A build configuration mismatch warning was introduced in
https://github.com/flutter/flutter/pull/169395 to help handle
dev_dependencies relying on the build configuration. However, we
disabled dev_dependencies from being excluded per configuration in
https://github.com/flutter/flutter/pull/171015. This warning therefore
can also be removed.

Fixes https://github.com/flutter/flutter/issues/174015.
