ea4cdcf39e remove conditional code for handling very old AGP versions (#162053)
I think code paths for AGP version <7 aren't needed anymore.

I can also imagine it will be hard to do such dynamic stuff in Kotlin,
so it's better to get rid of it.

Also, I added some explicit types, this reduces the amount of
grey/unresolved identifiers in IntelliJ by quite a lot, making it easier
to understand code (again, this should help in conversion to Kotlin
later on).

c6c518653c Fix NavigationBar indicator overlay color (#164484)
## Description

This PR fixes NavigationBar lacking visual feedback on the active
destination indicator.

### Before:

The navigation indicator does not change color when hovered or focused:


https://github.com/user-attachments/assets/a1e67dee-4a38-4711-ba90-bdcd9bed3226


### After:

The navigation indicator color changes (slightly darker):


https://github.com/user-attachments/assets/1b1cc335-2cf4-4c41-9c53-696537707c72


## Related Issue

Fixes [NavigationBar lacks visual feedback when focused or
hovered](https://github.com/flutter/flutter/issues/163871)

## Tests

- Updates several helper functions which are used by several tests.
- Updates several test: adding an Ink widget changes the coordinates
used in several tests because these coordinates are now relative to the
Ink offset.
- Will impact fours golden tests which were capturing the bad behavior
(indicator color not changing when hovered or focused).

6aaa4eb9e3 [framework]Add semantics role to table rows. (#163337)
**1. framework side:**
This PR Create semantics node for rows in table's
`assembleSemanticsNode` function.

**2. web side:**
I tested on my mac, and i need to remove the 
`<flt-semantics-container>` between table and row, row and cell to
traverse inside table, removing those transfom intermediate containers
on web will be a bit of hassle and will be in another separate PR.

For example this code can only announce table but can’t get into cells.
```
<flt-semantics id="flt-semantic-node-4" role="table" style="position: absolute; overflow: visible; width: 751px; height: 56px; transform-origin: 0px 0px 0px; transform: matrix(1, 0, 0, 1, 0, 56); pointer-events: none; z-index: 1;">
    <flt-semantics-container style="position: absolute; pointer-events: none; top: 0px; left: 0px;">
        <flt-semantics id="flt-semantic-node-6" role="row" style="position: absolute; overflow: visible; width: 751px; height: 56px; top: 0px; left: 0px; pointer-events: none;">
            <flt-semantics-container style="position: absolute; pointer-events: none; top: 0px; left: 0px;">
                <flt-semantics id="flt-semantic-node-5" role="columnheader" aria-label="Name" style="position: absolute; overflow: visible; width: 751px; height: 56px; top: 0px; left: 0px; pointer-events: all;"></flt-semantics>
            </flt-semantics-container>
        </flt-semantics>
    </flt-semantics-container>
</flt-semantics>
```
If I removed the in between `</flt-semantics-container>`, the code come 
```
<flt-semantics id="flt-semantic-node-4" role="table" style="position: absolute; overflow: visible; width: 751px; height: 56px; transform-origin: 0px 0px 0px; transform: matrix(1, 0, 0, 1, 0, 56); pointer-events: none; z-index: 1;">
    <flt-semantics id="flt-semantic-node-6" role="row" style="position: absolute; overflow: visible; width: 751px; height: 56px; top: 0px; left: 0px; pointer-events: none;">
        <flt-semantics id="flt-semantic-node-5" role="columnheader" aria-label="Name" style="position: absolute; overflow: visible; width: 751px; height: 56px; top: 0px; left: 0px; pointer-events: all;"></flt-semantics>
    </flt-semantics>
</flt-semantics>
```
And I can get into table cells.


**3. Other aria-attributes:** 

[aria-colcount](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Attributes/aria-colcount) ,[aria-rowcount](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Attributes/aria-rowcount) 
[aria-colindex](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Attributes/aria-colindex) 
[aria-rowindex](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Attributes/aria-rowindex) 
* theres attributes are only needed if some rows and columns are hidden
in the Dom tree. havn't added them yet

aria-rowspan , aria-colspan : 
*we currently don't support row span and col span in our widgets.

df676dc6e7 Add onHover and onFocusChange callbacks for TabBar (#164816)
Fixes https://github.com/flutter/flutter/issues/159444
Fixes https://github.com/flutter/flutter/issues/146089

This adds callbacks to TabBar for onHover and onFocusChange.
They pipe through to the underlying Inkwell widget that is wrapped
around each Tab of the TabBar during build.

#### Alternatives

- I did consider adding these callbacks to Tab instead, but felt that
going through TabBar would be better. If implemented in Tab, the user
would need to define callbacks for each tab. This PR makes it so there
is only need for one callback, and the associated Tab index is provided.
Also, since the Inkwell is applied in the TabBar, it's kludgy to have to
extract that from the Tabs _in_ TabBar later to pass on to the Inkwell.
👃
- Digging in to the requests in the linked issues, the user wants to
change various stylings in response to these events.
WidgetStateProperties were considered, but there are so many potential
styling properties that going this route would require greatly
increasing the API surface here. Tab.child allows the user to provide
whatever widget they would like to have as the content. Being able to
modify Tab.child in response to these events is a better way go instead
of exposing a ton of different properties.

9af4d746df Added semanticsIdentifier to Text Widgets (#163843)
This PR aims to add `semanticsIdentifier` to `Text` and some of its
internal objects to pass the semantics information for adding identifier
to the semantics nodes

From the issue filed at #163842, the following is a description of the
problem.

The [semantics
identifier](https://api.flutter.dev/flutter/semantics/SemanticsData/identifier.html)
helps in uniquely identifying elements using UI automation tools like
Appium, UIAutomator and XCUITests by setting identifiers that the screen
readers cannot see but the said tools can. This is especially useful
when working with a multi-lingual or multi-tenant app, where the element
IDs need to be unique but the content can be different. The `Semantics`
widget already has support for declaring it. However, the `Text` and
`Text.rich` variants only support setting `semanticsLabel` without
explicitly setting the identifiers. The widgets themselves can be
wrapped with a `Semantics` widget but it still does not cater for a rich
text that can have multiple text spans, each containing unique lables
and identifiers, and optionally gesture detectors for handling links.

Consider the following UI for two different tenants:
<img width="229" alt="Image"
src="https://github.com/user-attachments/assets/e8a24588-d94d-42fc-ba6c-ce39959207ae"
/>

Here, both the tenants utilise different strings to convey the same
message. The structure of the message stays the same so the identifiers
help in unifying the element identification process across the tenant
apps in the automation tools without having to write another script for
every other tenant.
Without the identifiers, the automation scripts require a rewrite per
tenant to be able to successfully locate the element and even tap on the
hyperlink.

# With PR Changes
## Appium Views
For the given sample code,
<details><summary>Text.rich Sample</summary>

```dart
Text.rich(
  TextSpan(
    text: 'This text contains both identifier and label.',
    semanticsLabel: 'Custom label',
    semanticsIdentifier: 'Custom identifier',
    style: customStyle1,
    children: <TextSpan>[
      TextSpan(
        text: ' While this one contains only label',
        semanticsLabel: 'Hello world',
        style: customStyle2,
      ),
      const TextSpan(
        text: ' and this contains only identifier,',
        semanticsIdentifier: 'Hello to the automation tool',
      ),
      TextSpan(
        text: ' this text contains neither identifier nor label.',
        style: customStyle2,
      ),
    ],
  ),
),
```
</details>
we have the following results with and without the PR code changes:

03f1208721 Fix SwiftPM scheme migration to handle when there are no BuildActionEntries (#164660)
An Xcode scheme may or may not have `BuildActionEntries`. When migrating
to SwiftPM, if Flutter cannot find `BuildActionEntries` in the xcscheme,
append the `PreAction` to the end of the `BuildAction`.

Fixes https://github.com/flutter/flutter/issues/163086.

a7a4d0bd2b Write macOS universal gen_snapshot binaries to a separate output directory (#164667)
Also use the name "gen_snapshot" when building for Android targets
instead of appending a target architecture to the filename.

This allows flutter_tools to find the universal gen_snapshot binary when
using a locally built engine. Previously the tools would search
directories like "clang_x64" and find build outputs that may not match
the host architecture.

Moving the universal gen_snapshot binary to a separate directory avoids
conflicts with Dart's gen_snapshot binary, which is placed at the root
of the target output directory.

6316b48bca Check for a null codec in MultiFrameImageStreamCompleter after calling _emitFrame (#165009)
_emitFrame invokes image listeners. A listener callback could remove all
of the MultiFrameImageStreamCompleter's listeners, resulting in a
_maybeDispose call that destroys the codec.

0bdb4d68b5 [flutter_tools] Call reassemble with DWDS 24.3.7 and update hot reload and restart analytics (#165006)
https://github.com/dart-lang/webdev/issues/2584

Reassemble was being called in DWDS in the injected client until
v24.3.7. Flutter tools should now instead be the one to call the service
extension. Now that it's in Flutter tools, we can also report how long
it took. Similarly, we should update analytics on various things like,
whether there was a reload rejection, how long the compile took, and
more.

Adds test to check that these analytics are being reported correctly.

7bf8837116 Clarify performacne of SingleTickerProviderStateMixin vs TickerProviderStateMixin (#164870)
Adds the following line to
[TickerProviderStateMixin](https://api.flutter.dev/flutter/widgets/TickerProviderStateMixin-mixin.html):

>Using one [TickerProviderStateMixin] twice is more efficient than two
[SingleTickerProviderStateMixin]s.

This is based on a discussion on Flutter Discord with @chunhtai. From
what I understood, creating multiple `SingleTickerProviderStateMixin`s
is more expensive because you need two different state which is
relatively costly compared to having just one. Not sure if this line
should should be qualified like "Using one [TickerProviderStateMixin]
twice is *generally* more efficient than two
[SingleTickerProviderStateMixin]s" or similar.

This change should be reviewed for correctness as I don't actually
understand enough about the difference between
`TickerProviderStateMixin` and `SingleTickerProviderStateMixin`.

Closes #164869

<details>

<summary>
Example case where this was relevant (click)
</summary>

I was avoiding using `TickerProviderStateMixin` like so:

```dart
    _animationController = AnimationController.unbounded(vsync: this)
      ..addListener(() {
        _updateScale(_animationController.value);
      });
   
    //could have just set `vsync` to `this` if using `TickerProviderStateMixin`
    WidgetsBinding.instance.addPostFrameCallback((_) {
      _verticalAnimationController =
          AnimationController.unbounded(vsync: _verticalController.position.context.vsync)
            ..addListener(() {
              _verticalController.jumpTo(_verticalAnimationController.value);
            });

      _horizontalAnimationController =
          AnimationController.unbounded(vsync: _horizontalController.position.context.vsync)
            ..addListener(() {
              _horizontalController.jumpTo(_horizontalAnimationController.value);
            });
    });
```

Instead of just:

```dart
    _animationController = AnimationController.unbounded(vsync: this)
      ..addListener(() {
        _updateScale(_animationController.value);
      });

    _verticalAnimationController = AnimationController.unbounded(vsync: this)
      ..addListener(() {
        _verticalController.jumpTo(_verticalAnimationController.value);
      });

    _horizontalAnimationController = AnimationController.unbounded(vsync: this)
      ..addListener(() {
        _horizontalController.jumpTo(_horizontalAnimationController.value);
      });
```

b35c6be8c9 Add withDurationAndBounce to SpringDescription (#164411)
Part of https://github.com/flutter/flutter/issues/152587

###  Description:
With `withDurationAndBounce` (we could also rename to `withDuration`),
the user only has to worry about a single attribute: the bounce (and
duration, but they would have to worry with duration anyway. If they
don't, there is a default value already). The standard
`SpringDescription` has 3 values, so it is way more abstract. This
should help a lot people to make beautiful spring animations using
Flutter.

<img width="838" alt="image"
src="https://github.com/user-attachments/assets/4d0dccc7-0f97-4a13-99a4-268228b87f08"
/>

### Negative bounce:

I didn't enable bounce to be negative because the behavior is super
tricky. I don't know what formula Apple is using, but seems like it is
not public. There are many different formulas we can use, including the
one provided on the original issue, but then there is the risk of people
complaining it works differently than SwiftUI. I need to check if other
projects (react-spring, framer motion) support negative bounce, but
feels like this is something 99.9999% of people wouldn't expect or use,
so I think we are safe. I couldn't find a single usage of negative
bounce on Swift in all GitHub (without a duration, using code-search, vs
5k cases with positive values). Not even sure the todo is needed, but
won't hurt.


### Comparison

<details>
  <summary>Dart vs Swift testing results</summary>

```dart
 testWidgets('Spring Simulation Tests - Matching SwiftUI', (WidgetTester tester) async {
      // Test cases matching the Swift code's ranges
      List<({Duration duration, double bounce})> testCases = [
        (duration: const Duration(milliseconds: 100), bounce: 0.0),
        (duration: const Duration(milliseconds: 100), bounce: 0.3),
        (duration: const Duration(milliseconds: 100), bounce: 0.8),
        (duration: const Duration(milliseconds: 100), bounce: 1.0),
        (duration: const Duration(milliseconds: 500), bounce: 0.0),

        (duration: const Duration(milliseconds: 1000), bounce: 0.8),
        (duration: const Duration(milliseconds: 1000), bounce: 1.0),
        (duration: const Duration(milliseconds: 2000), bounce: 0.0),
        (duration: const Duration(milliseconds: 2000), bounce: 0.3),
        (duration: const Duration(milliseconds: 2000), bounce: 0.8),
        (duration: const Duration(milliseconds: 2000), bounce: 1.0),
      ];

      for (final testCase in testCases) {
        SpringDescription springDesc = SpringDescription.withDurationAndBounce(
          duration: testCase.duration,
          bounce: testCase.bounce,
        );

        print(
          'Duration: ${testCase.duration.inMilliseconds / 1000}, Bounce: ${testCase.bounce}, Mass: ${springDesc.mass}, Stiffness: ${springDesc.stiffness}, Damping: ${springDesc.damping}',

84b38b8dfc Make LLDB check a warning instead of a failure (#164828)
We added LLDB file in https://github.com/flutter/flutter/pull/164344.
This adjusts it so if the LLDB file is missing it gives a warning rather
than an error that fails the build.

83781ae65c RoundSuperellipse algorithm v3: Ultrawideband heuristic formula (#164755)
This PR revises the algorithm for RoundSuperellipses, replacing the
current "max ratio" approximation with an algorithm that works for
ratios from 2.0 to infinity.

The previous "max ratio" approximation, which replaces the middle of
edges with straight lines when the ratio is above 2.3, turns out to
produce results too close to classic RRects. After reexamining the
shapes and more calculation, I discovered that the max-ratio
approximation is flawed. Even squircles with with really high ratios
(~100) have a significant part of the edges that must not be
approximated by straight lines.

The new version is much closer to native.

### Comparison
Native: (Notice the long wedgy gap at the end of curves)
<img
src="https://github.com/user-attachments/assets/61b60191-7d45-4c49-9e09-b0422243cd8c"

Before PR: (Notice the short wedgy gap at the end of curves)
<img
src="https://github.com/user-attachments/assets/15ea374b-4b16-4187-aaa4-94f432fbb61e"
width="400"/>

After PR:
<img
src="https://github.com/user-attachments/assets/973ef4d1-7c26-44a9-b45e-10d109d5618b"
width="400"/>

Another example (after PR). Even though the rectangular RSE has ratios
of around 4, there are still curvature near the middle section of edges,
which can be identified with the help of antialias pixels.
<img width="838" alt="image"
src="https://github.com/user-attachments/assets/5078d098-c582-48a8-81e5-615909def675"
/>

### Details

I found that `n` has really good linearity towards larger ratios.

<img width="844" alt="image"
src="https://github.com/user-attachments/assets/73e99e45-a0f0-450b-8e2b-f6fd97082958"
/>

I also found a good candidate for the precomputed unknown (called
`k_xJ`), which has a smooth curve at the beginning and almost straight
line towards larger `n`, removing the need to cap the scope of
application of the formula.

<img width="1203" alt="image"
src="https://github.com/user-attachments/assets/67664898-2dbd-4f00-a9ba-d76030cf3742"
/>

The algorithm for paths are also updated in a similar way and
approximated the Bezier factors with heuristic formulae for bigger `n`s.
I've also verified that the path deviates from the geometry by no more
than 0.01% over the range of n [15, 100]

Theoretically removing "stretch" should simplify the algorithms.
Unfortunately I had to spend more lines to process cases of zero radii,
which were conveniently handled by stretches.

b7bea22ab8 [Widget Inspector] Handle null exceptions calling renderObject (#163642)
Fixes https://github.com/flutter/devtools/issues/8905

Based on the stacktrace in
https://github.com/flutter/devtools/issues/8905:

* This call to `renderObject` can throw a null-exception:
39b4951f8f/packages/flutter/lib/src/widgets/framework.dart (L3745)
* That exception is thrown here:
39b4951f8f/packages/flutter/lib/src/widgets/framework.dart (L6534)

I've been unable to figure out a way to get into a state that reproduces
this. Instead, this PR simply handles the exception and returns `null`
(because we already gracefully handle the case where the `renderObject`
is `null`.

eb07c51230 Add lldb init file (#164344)
Adds an .lldbinit file to iOS app xcscheme.

Adding to scheme files can be error prone since a developer may be using
custom schemes (flavors). If we can't add it to the scheme, we print an
error without failing.

Since it is part of the scheme, it will be added to the project and will
be used on every run regardless of the device type/version. The Dart
side handles limiting to specific devices. If needed, we can alter the
.lldbinit file during `flutter assemble` to rewrite it since it doesn't
read the file until launch time (therefore it can be changed during
build time).

During `flutter assemble`, if the project doesn't have an LLDB Init File
set for any schemes, it'll throw an error if running in debug mode with
an iOS 18.4+ device.

86e4c12a06 Use dwds 24.3.6 and pass uri for the reload scripts path to FrontendServerDdcLibraryBundleProvider (#164582)
The path to reload scripts JSON was being added to the global window
before. It should instead be passed to the provider on setup. In order
to do this, the baseUri calculation is moved into the WebAssetServer.
This is safe because Flutter tools was calculating it immediately
after creating the server anyways.

https://github.com/dart-lang/webdev/issues/2584

Existing hot reload tests should test this behavior.

b771b39813 Enforce minSdk constraint for Android Flutter (#164251)
This commit adds validation for the Android SDK version within the
existing dependency version checker. It introduces a warning when the
SDK version is below a predefined threshold. The validation checks for
the `minSdk` property in the `android` block of the app's `build.gradle`
file. It will warn users if their `minSdk` version is out of Flutter's
supported
range and guide them on how to fix it.

Fixes https://github.com/flutter/flutter/issues/134570

0357b45337 Add clipRSuperellipse, and use them for dialogs (#161111)
This PR makes Flutter support `clipRSuperellipse`, and apply it to
`CupertinoAlertDialog`.

Hit tests related to RSuperellipse are performed based on its bounding
box, since the computation is too complicated and pixel perfect hit test
is not needed practically.

7d8c78ce20 [A11y] Add radio group role (#164154)
This adds a new "radio group" accessibility role to `dart:ui` and the
Flutter web engine.

This does not update existing widgets to use this new role. Currently,
users must manually add a `Semantics` widget to use this accessibility
role. See the example app below.

Part of: https://github.com/flutter/flutter/issues/162093

## Example app

<details>
<summary>Example app that uses the radio group role...</summary>

```dart
import 'dart:ui';

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

void main() {
  runApp(const RadioExampleApp());
  SemanticsBinding.instance.ensureSemantics();
}

class RadioExampleApp extends StatelessWidget {
  const RadioExampleApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: const Text('Radio Sample')),
        body: const Center(child: RadioExample()),
      ),
    );
  }
}

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

  @override
  State<RadioExample> createState() => _RadioExampleState();
}

class _RadioExampleState extends State<RadioExample> {
  int _groupValue = 0;

  @override
  Widget build(BuildContext context) {
    return Semantics(
      label: 'Radio group',
      role: SemanticsRole.radioGroup,
      explicitChildNodes: true,
      child: Column(
        children: <Widget>[
          ListTile(
            title: const Text('Foo'),
            leading: Radio<int>(
              value: 0,
              groupValue: _groupValue,
              onChanged: (int? value) => setState(() => _groupValue = value ?? 0),
            ),
          ),
          ListTile(
            title: const Text('Bar'),
            leading: Radio<int>(
              value: 1,
              groupValue: _groupValue,
              onChanged: (int? value) => setState(() => _groupValue = value ?? 0),
            ),
          ),

ac7118832d Add a isSystemTextScaler matcher (#160120)
This is for https://github.com/flutter/flutter/pull/159999. That PR
breaks registered tests so a new matcher is added for soft transition &
making it slightly easier to write tests that verify nothing is
shadowing the system text scaler in the widget tree.

If this approach sounds plausible & gets merged, I'm going to:
1. remake the breaking change announcement 
2. update the migration guide with the new matcher,
3. migrate the registered tests and mark #159999 as ready for review.

71d50a1616 Start using bin/cache/engine.{stamp|realm} instead of bin/internal/engine.{realm|version}. (#164352)
Towards https://github.com/flutter/flutter/issues/164315.

See also:
https://github.com/flutter/flutter/blob/master/docs/tool/Engine-artifacts.md.

There are more usages in `flutter/flutter`, but some will require more
specialized review (i.e. from release folks, or the Dart SDK team), so
I'll split those off.

~~Requires https://github.com/flutter/flutter/pull/164317 to merge
first.~~

246d6c6834 Make pressing and moving on CupertinoButton closer to native behavior. (#161731)
Fixes: #91581 

This PR adds an `onTapMove` event to `TapGestureRecognizer`, and then
`CupertinoButton` uses this event to implement the behavior of the
native iOS `UIButton` (as shown in the issue). It is worth noting that
this PR slightly changes the way `CupertinoButton`'s `onPressed` is
triggered. Specifically, it changes from being triggered by
`TapGestureRecognizer`'s `onTap` to checking if the event position is
still above the button in `TapGestureRecognizer`'s `onTapUp`.
Additionally, it removes the previous behavior where the gesture was
canceled if moved beyond `kScaleSlop` (18 logical pixels). Overall,
previously, `onPressed` could not be triggered if the button was pressed
and then moved more than 18 pixels. This PR adjusts it so that
`onPressed` cannot be triggered if the button is pressed and then moved
outside the button.

b8902e6a17 [tool] Allow using archiveName in android bundle build (#162390)
fixes #126971 

Also, for some reason, fixes #147261 , which shouldn't have been ever
broken since this case tested here:

b007899d3a/packages/flutter_tools/test/general.shard/android/gradle_find_bundle_test.dart (L153-L173)

-->

Key change here is replacing the optimistic approach of guessing the
filename based on buildInfo parameters with the actual discovery of
built artifacts on the filesystem. This change is needed because there
is no way the build can determine the archiveName from Gradle, which
differentiates this part from other parameters such as buildType and
flavor. Flutter build contains information about them, but not about the
base name.

556ae54358 Fix incorrectly checking for invalid environment variables in the tool (#164101)
<!--
Thanks for filing a pull request!
Reviewers are typically assigned within a week of filing a request.

https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md

This PR removes a check that looks for the use of Flutter version
related Dart define keys in the environment variables (not Dart defines)
of the user of the Flutter tool. We don't need to check the environment
variables, we only need to check the user defined Dart defines.

Here's how it currently works:

1. User builds a Flutter app via tool
2. tool checks environment variables for Flutter version related Dart
define keys and throws if it finds and (_and_)
3. tool checks list of user defined Dart defines for Flutter version
related Dart define keys and throws if it finds any

This PR removes the check in step 2, since step 3 is what we actually
care about.

The `FLUTTER_GIT_URL` environment variable is set on forks and the Dart
define is used to make that information available to applications at
runtime. However, environment variables don't propagate to be Dart
defines, thus the above mentioned check is not needed.

*List which issues are fixed by this PR. You must list at least one
issue. An issue is not required if the PR fixes something trivial like a
typo.*

Fixes #164093

*If you had to change anything in the [flutter/tests] repo, include a
link to the migration guide as per the [breaking change policy].*
