Remove jetifier usages from framework and engine (#173459)
Justification this is safe: 
useAndroidX which I left in this pr was added in 2018 and is one of 2
flags that control what compile behavior is used as android migrated
from the support library to androidx.
We (flutter android) believe we have migrated all support library usages
to android x.
Android Studio does not automatically insert the Jetifier flag in newly
created projects, suggesting a move towards less reliance on it.

I think even if plugins were using the support libraries this pr would
not break them because the targets being modified are tests in this repo
and the engine build which only uses androidx dependencies.

Migrate to list and builder Sliver convenience constructors (#173011)
In 2022, we introduced new convenience constructors like
`SliverList.builder` and `SliverList.list`. Unfortunately, LLMs like
Gemini seem to prefer the delegate pattern even when these convenience
constructors are usable. This updates Flutter's docs, code, and tests to
use these convenience constructors where possible. Hopefully this will
nudge LLMs to consider using the new APIs :)

I migrated 80% of the code by hand, and 20% using Gemini CLI. See
[go/loic-ai-log](http://goto.google.com/loic-ai-log) (Google internal)
for details.

There's a few locations that I wasn't able to migrate to the convenience
constructors due to missing APIs. I filed the following issues:

1. https://github.com/flutter/flutter/issues/173018
2. https://github.com/flutter/flutter/issues/173019

Add the 'windowing' feature flag and use to wrap an implementation for regular windows that always throws (#172478)
## What's new?

- Added the `windowing` feature flag to the project
- Created the internal `_window.dart` API with support for regular
windows
- Implemented a `_WindowingOwnerUnsupported` implementation of the
`WindowingOwner` interface
- Marked all points of the public API as `@internal` with a
corresponding warning documentation
- Threw an `UnsupportedError` where it is appropriate to do so

Note that this PR does **NOT** include a real implementation of
`WindowingOwner` (e.g. for win32 or macOS). That work will be opened as
a follow up.

This work is based off of https://github.com/flutter/flutter/pull/168697
and http://github.com/flutter/flutter/pull/168437, as well as this
design document:
https://docs.flutter.dev/go/multi-window-experimental-apis

Refactor Android platform view code in advance of enabling HCPP on existing PV widgets (behind a flag) (#170553)
Should introduce no behavior changes. Refactors the android platform
view code so that
1. The delegator is ready to delegate between PlatformViewsController
(PVC) 1 and 2, and implements a
`PlatformViewsChannel.PlatformViewsHandler`.
2. The `PlatformViewCreationRequest` and `PlatformViewTouch` are fully
shared between the two platform view modes
3. Introduces new factory constructors for the different types of
`PlatformViewCreationRequest`s, corresponding to the modes.

Making the flag work on existing widgets will be done in a follow up PR
here
67262d9240/engine/src/flutter/shell/platform/android/io/flutter/embedding/engine/systemchannels/PlatformViewsChannel.java (L95).

[web] Remove all usages of js_util. (#171871)
Closes https://github.com/flutter/flutter/issues/143396

### Description
- Removes `js_util` library usage across the codebase

In order to get rid of `dart.library.js_util` in
[`kIsWeb`](e8d56b25c0/packages/flutter/lib/src/foundation/constants.dart (L83))
constant the dart analyzer has to be updated first. For now, the
`dart.library.js_util` value is hardcoded in the source code:
1a88edceb7/pkg/analyzer/lib/src/dart/constant/evaluation.dart (L2908-L2915).
So we either have to update this value or wait for the
https://github.com/dart-lang/sdk/issues/50045 fix.

Reland "Add feature flags to the framework" (#171545)
This relands https://github.com/flutter/flutter/pull/168437. The google3
fixes were landed in: https://github.com/flutter/flutter/pull/171547,
https://critique.corp.google.com/cl/781275353,
https://github.com/flutter/flutter/pull/171933.

This PR is split into two commits:

1. d6253794e8982348c5c21cb63e8f6bf785664be6, code from
https://github.com/flutter/flutter/pull/168437 without any changes
2. f35d29e4af630d2d4fdb0cda8686b6ff9f77227a, updates the PR to omit
obvious types.

Original PR description:

## Motivation

We'd like to let users opt-in to experimental features so that they can
give early feedback while we iterate on the feature. For example:

Example feature flags:

1. Android sensitive content:
https://github.com/flutter/flutter/pull/158473. When enabled, Flutter
will tell Android when the view contains sensitive content like a
password.
3. Desktop multi-window. When enabled, Flutter will use child windows to
allow things like a context menu to "escape" outside of the current
window.

### Use case

Users will be able to turn on features by:

* **Option 1**: Run `flutter config --enable-my-feature`. This enables
the feature for all projects on the machine
* **Option 2**: Add `enable-my-feature: true` in their `pubspec.yaml`,
under the `flutter` section. This would enable the for a single project
on the machine.

Turning on a feature affects _both_ development-time (`flutter run`) and
deployment-time (`flutter build x`). For example, I can `flutter build
windows` to create an `.exe` with multi-window features enabled.

## How this works

This adds a new
[`runtimeId`](https://github.com/flutter/flutter/pull/168437/files#diff-0ded384225f19a4c34d43c7c11f7cb084ff3db947cfa82d8d52fc94c112bb2a7R243-R247)
property to the tool's `Feature` class. If a feature is on and has a
`runtimeId`, its `runtimeId` will be [stamped into the Dart application
as a Dart
define](https://github.com/flutter/flutter/pull/168437/files#diff-bd662448bdc2e6f50e47cd3b20b22b41a828561bce65cb4d54ea4f5011cc604eR293-R327).
The framework uses this Dart define to [determine which features are
enabled](https://github.com/flutter/flutter/pull/168437/files#diff-c8dbd5cd3103bc5be53c4ac5be8bdb9bf73e10cd5d8e4ac34e737fd1f8602d45).

### Multi-window example

https://github.com/flutter/flutter/pull/168697 shows how this new
feature flag system can be used to add a multi-window feature flag:

1. It adds a new [multi-window
feature](https://github.com/flutter/flutter/pull/168697/files#diff-0ded384225f19a4c34d43c7c11f7cb084ff3db947cfa82d8d52fc94c112bb2a7R189-R198)
to the Flutter tool. This can be turned on using `flutter config
--enable-multi-window` or by putting `enable-multi-window: true` in an
app's .pubspec, under the `flutter` section.
2. It adds a new
[`isMultiWindowEnabled`](https://github.com/flutter/flutter/pull/168697/files#diff-c8dbd5cd3103bc5be53c4ac5be8bdb9bf73e10cd5d8e4ac34e737fd1f8602d45R7-R11)
property to the framework.
4. The Material library can use this new property to determine whether
it should create a new window.
[Example](https://github.com/flutter/flutter/pull/168697/files#diff-2cbc1634ed6b61d61dfa090e7bfbbb7c60b74c8abc3a28df6f79eee691fd1b73).

## Limitations

### Tool and framework only

For now, these feature flags are available only to the Flutter tool and
Flutter framework. The flags are not automatically available to the
embedder or the engine.

For example, embedders need to configure their surfaces differently if
Impeller is enabled. This configuration must happen before the Dart
isolate is launched. As a result, the framework's feature flags is not a
viable solution for this scenario for now. For these kinds of scenarios,
we should continue to use platform-specific configuration like the
`AndroidManifest.xml` or `Info.plist` files.

This is a fixable limitation, we just need to invest in this plumbing :)

### Tree shaking

Feature flags are not designed to help tree shaking. For example, you
cannot conditionally import Dart code depending on the enabled feature
flags. Code that is feature flagged off will still be imported into
user's apps.

## Motivation

We'd like to let users opt-in to experimental features so that they can
give early feedback while we iterate on the feature. For example:

Example feature flags:

1. Android sensitive content:
https://github.com/flutter/flutter/pull/158473. When enabled, Flutter
will tell Android when the view contains sensitive content like a
password.
2. Desktop multi-window. When enabled, Flutter will use child windows to
allow things like a context menu to "escape" outside of the current
window.

### Use case

Users will be able to turn on features by:

* **Option 1**: Run `flutter config --enable-my-feature`. This enables
the feature for all projects on the machine
* **Option 2**: Add `enable-my-feature: true` in their `pubspec.yaml`,
under the `flutter` section. This would enable the for a single project
on the machine.

Turning on a feature affects _both_ development-time (`flutter run`) and
deployment-time (`flutter build x`). For example, I can `flutter build
windows` to create an `.exe` with multi-window features enabled.

## How this works

This adds a new
[`runtimeId`](https://github.com/flutter/flutter/pull/168437/files#diff-0ded384225f19a4c34d43c7c11f7cb084ff3db947cfa82d8d52fc94c112bb2a7R243-R247)
property to the tool's `Feature` class. If a feature is on and has a
`runtimeId`, its `runtimeId` will be [stamped into the Dart application
as a Dart
define](https://github.com/flutter/flutter/pull/168437/files#diff-bd662448bdc2e6f50e47cd3b20b22b41a828561bce65cb4d54ea4f5011cc604eR293-R327).
The framework uses this Dart define to [determine which features are
enabled](https://github.com/flutter/flutter/pull/168437/files#diff-c8dbd5cd3103bc5be53c4ac5be8bdb9bf73e10cd5d8e4ac34e737fd1f8602d45).

### Multi-window example

https://github.com/flutter/flutter/pull/168697 shows how this new
feature flag system can be used to add a multi-window feature flag:

1. It adds a new [multi-window
feature](https://github.com/flutter/flutter/pull/168697/files#diff-0ded384225f19a4c34d43c7c11f7cb084ff3db947cfa82d8d52fc94c112bb2a7R189-R198)
to the Flutter tool. This can be turned on using `flutter config
--enable-multi-window` or by putting `enable-multi-window: true` in an
app's .pubspec, under the `flutter` section.
2. It adds a new
[`isMultiWindowEnabled`](https://github.com/flutter/flutter/pull/168697/files#diff-c8dbd5cd3103bc5be53c4ac5be8bdb9bf73e10cd5d8e4ac34e737fd1f8602d45R7-R11)
property to the framework.
3. The Material library can use this new property to determine whether
it should create a new window.
[Example](https://github.com/flutter/flutter/pull/168697/files#diff-2cbc1634ed6b61d61dfa090e7bfbbb7c60b74c8abc3a28df6f79eee691fd1b73).

## Limitations

### Tool and framework only

For now, these feature flags are available only to the Flutter tool and
Flutter framework. The flags are not automatically available to the
embedder or the engine.

For example, embedders need to configure their surfaces differently if
Impeller is enabled. This configuration must happen before the Dart
isolate is launched. As a result, the framework's feature flags is not a
viable solution for this scenario for now. For these kinds of scenarios,
we should continue to use platform-specific configuration like the
`AndroidManifest.xml` or `Info.plist` files.

This is a fixable limitation, we just need to invest in this plumbing :)

### Tree shaking

Feature flags are not designed to help tree shaking. For example, you
cannot conditionally import Dart code depending on the enabled feature
flags. Code that is feature flagged off will still be imported into
user's apps.

Normalize input decoration theme (#168981)
This PR is to make `InputDecorationTheme` conform to Flutter Material's
conventions for component themes:

- Added a `InputDecorationThemeData` class which defines overrides for
the defaults for `InputDecorator` properties.
- Added `InputDecorationTheme` constructor parameters:
`InputDecorationThemeData? data` and `Widget? child`. This is now the
preferred way to configure a `InputDecorationTheme`:

```dart
InputDecorationTheme(
	data: InputDecorationThemeData(
	    filled: true,
	    fillColor: Colors.amber,
	    ...
	  ),
  	child: const TextField()
)
```
These two properties are made nullable to not break existing apps which
has customized `ThemeData.inputDecorationTheme`.

- Update `InputDecorationTheme` to be an `InheritedTheme` subclass.
- Changed the type of component theme defaults from
`InputDecorationTheme` to `InputDecorationThemeData`.
- Changed the `InputDecorationTheme bottomAppBarTheme` property to
`Object? bottomAppBarTheme` in `ThemeData` and `ThemeData.copyWith()`
(Object? is used for the moment to minimize Google tests failure. A
follow-up PR will replace `Object?` with `InputDecorationThemeData`.
- Addresses the "theme normalization" sub-project within #91772.

A migration guide will be created on website repo.

Pause UIScene migration (#170490)
UIScene migration is not yet enforced by Apple so we have some more time
to handle this. Let's pause on auto-migrating projects.

Reland of https://github.com/flutter/flutter/pull/170457.

This PR differs as it keeps our tests migrated to UI Scene lifecycle.

Workspace (#169556)
Reland after https://github.com/flutter/flutter/issues/169844.

Switch Flutter to use pub workspaces as a preparation to unpin selected
packages.

Assumptions:

1. No packages in this repository are published to pub.dev --> We can
use `any` dependencies in most local pubspecs, as the global constraint
defines the version. An exception are the packages used outside of this
repo with an `sdk` dependency, namely `flutter_localizations`,
`flutter_test`, and `flutter`.
2. The "universes" `{flutter_tools}` and `{flutter,
flutter_localizations, flutter_goldens}` can use different packages
versions, as they are not resolved together. --> We do not need to
upgrade them in sync, we can first do one "universe", then the other.

Based on these assumptions, we use
https://github.com/mosuem/pubspec_merger.dart to merge all packages in
the `flutter` universe into a top-level pub workspace.

The `flutter` and `flutter_tools` workspaces being separate also ensures
that changes to `flutter` will not inadvertently break `flutter_tools`,
with not-so-nice consequences for our users which would be unable to run
`flutter upgrade`.

There is a third "top-level" pubspec besides `./pubspec.yaml` and
`packages/flutter_tools/pubspec.yaml`, namely
`packages/flutter_tools/.../widget_preview_scaffold/pubspec.yaml`. This
is an artifact due to it living under `flutter_tools`, so it can't be
part of the `./pubspec.yaml` workspace. Moving it would be a larger
change, and out of the scope of this PR.

This required a rewrite of the update-packages tool, but the main
functionality stays the same, as well as the argument names, to ensure a
seamless transition.

previous https://github.com/flutter/flutter/pull/167363

I have to factor out abstract class for RadioGroupRegistry and
RadioClient which are subclassed by RadioGroupState and RawRadio
respectively.

I have to do this because the RadioListTile that has 2 focusnode one for
listTile and one for the radio it builds. The issue is that RadioGroup's
keyboard shortcut has to tightly couples with the focus node of each
radio, but the radioListtile has to mute the radio's focusnode so it can
act as one control under keyboard shortcut

d582b35809/packages/flutter/lib/src/material/radio_list_tile.dart (L484)

Therefore i abstract the out the logic of RadioGroup so that another
widget can participate by implementing the interface.

[Reland3] Implements UISceneDelegate dynamically w/ FlutterLaunchEngine (#169276) (#169365)
## **BREAKING CHANGE**

Adopting Apple's UISceneDelegate protocol shifts the initialization
order of apps. For the common cases we've made sure they will work
without change. The one case that will require a change is any app that
in `-[UIApplicateDelegate didFinishLaunchingWithOptions:]` assumes that
`UIApplicationDelegate.window.rootViewController` is a
`FlutterViewController` instance. Users should follow the [migration
guide](https://docs.google.com/document/d/16WsqYbANmhupw-gxGPQPZ9B3yz1YBIviS-N1UyIQNSE/edit?tab=t.0#heading=h.txry2otwqko3)
to update that usage.

## Changes since revert
It's been rebased onto the FlutterPluginRegistrant PR which was used for
migration. The dynamic selection of the UISceneDelegate has been
removed, instead there is a flutter tool migration to the Info.plist.

Validate build configuration during Xcode build phase (#169395)
You can run iOS/macOS Flutter apps through either the Flutter CLI or
Xcode. However, it's often required to first run the Flutter CLI to
generate required files and settings. Some of these settings/files (like
dev dependencies) are specific to the build mode. However, you can
change the build mode through Xcode too. When you change the build mode
through Xcode, the Flutter-generated files and setting may not be
correct.

This PR checks if the current build mode matches the one last used by
the Flutter CLI. If it doesn't, it'll print a warning like this:

If the build action is `install`, which indicates the app is being built
for distribution, this will print as an error and fail the build:

integration_tests: Check if BuildContext is mounted in display_cutout_test (#169008)

The `use_build_context_synchronously` lint rule is changing to catch

[Cupertino] Apply RSuperellipse to most Cupertino widgets (#167784)
This PR applies RSuperellipse to most Cupertino widgets. I got the list
by searching for `ClipRRect`, `drawRRect`, and `BoxDecoration` (with
`borderRadius`) through the package. They're replaced by
`ClipRSuperellipse`, `drawRSuperellipse`, and `ShapeDecoration`
respectively.

There are a few widgets that I didn't apply:
* `CupertinoTextField` as well as its related widget
`CupertinoSearchTextField`, because `CupertinoTextField` expects a
`BoxDecoration` argument. Migrating it is nontrivial and will take place
in a separate PR.
* `CupertinoTextSelectionToolbar`, because it seems complicated
(containing a lot of paths). I wonder if it's possible to replace the
clipPath with clipRRect/clipRSe for better performance.
* `CupertinoSwitch`. I suspect it's not an squircle since it tightly
contains a full circle.

Fixes https://github.com/flutter/flutter/issues/13914.

This change reverts the following previous change:
Reland after #169357.

Switch Flutter to use pub workspaces as a preparation to unpin selected
packages.

Assumptions:

1. No packages in this repository are published to pub.dev --> We can
use `any` dependencies in most local pubspecs, as the global constraint
defines the version. An exception are the packages used outside of this
repo with an `sdk` dependency, namely `flutter_localizations`,
`flutter_test`, and `flutter`.
2. The "universes" `{flutter_tools}` and `{flutter,
flutter_localizations, flutter_goldens}` can use different packages
versions, as they are not resolved together. --> We do not need to
upgrade them in sync, we can first do one "universe", then the other.

Based on these assumptions, we use
https://github.com/mosuem/pubspec_merger.dart to merge all packages in
the `flutter` universe into a top-level pub workspace.

The `flutter` and `flutter_tools` workspaces being separate also ensures
that changes to `flutter` will not inadvertently break `flutter_tools`,
with not-so-nice consequences for our users which would be unable to run
`flutter upgrade`.

There is a third "top-level" pubspec besides `./pubspec.yaml` and
`packages/flutter_tools/pubspec.yaml`, namely
`packages/flutter_tools/.../widget_preview_scaffold/pubspec.yaml`. This
is an artifact due to it living under `flutter_tools`, so it can't be
part of the `./pubspec.yaml` workspace. Moving it would be a larger
change, and out of the scope of this PR.

This required a rewrite of the update-packages tool, but the main
functionality stays the same, as well as the argument names, to ensure a
seamless transition.

Use pub workspace (#168662)
Switch Flutter to use pub workspaces as a preparation to unpin selected
packages.

Assumptions:

1. No packages in this repository are published to pub.dev --> We can
use `any` dependencies in most local pubspecs, as the global constraint
defines the version. An exception are the packages used outside of this
repo with an `sdk` dependency, namely `flutter_localizations`,
`flutter_test`, and `flutter`.
2. The "universes" `{flutter_tools}` and `{flutter,
flutter_localizations, flutter_goldens}` can use different packages
versions, as they are not resolved together. --> We do not need to
upgrade them in sync, we can first do one "universe", then the other.

Based on these assumptions, we use
https://github.com/mosuem/pubspec_merger.dart to merge all packages in
the `flutter` universe into a top-level pub workspace.

The `flutter` and `flutter_tools` workspaces being separate also ensures
that changes to `flutter` will not inadvertently break `flutter_tools`,
with not-so-nice consequences for our users which would be unable to run
`flutter upgrade`.

There is a third "top-level" pubspec besides `./pubspec.yaml` and
`packages/flutter_tools/pubspec.yaml`, namely
`packages/flutter_tools/.../widget_preview_scaffold/pubspec.yaml`. This
is an artifact due to it living under `flutter_tools`, so it can't be
part of the `./pubspec.yaml` workspace. Moving it would be a larger
change, and out of the scope of this PR.

This required a rewrite of the update-packages tool, but the main
functionality stays the same, as well as the argument names, to ensure a
seamless transition.

This change reverts the following previous change:
## **BREAKING CHANGE**

Adopting Apple's UISceneDelegate protocol shifts the initialization
order of apps. For the common cases we've made sure they will work
without change. The one case that will require a change is any app that
in `-[UIApplicateDelegate didFinishLaunchingWithOptions:]` assumes that
`UIApplicationDelegate.window.rootViewController` is a
`FlutterViewController` instance. This is sometimes done to register
platform channels directly on the `FlutterViewController`. Instead users
should use the `FlutterPluginRegistry` API's to create platform channels
in `-[UIApplicateDelegate didFinishLaunchingWithOptions:]`, like
`FlutterPlugin`s do.

An example can be seen here:

https://github.com/flutter/flutter/pull/168914/files#diff-9f59c5248b58124beca7e290a57646023cda3ca024607092c6c6932606ce16ee

In extreme cases, like bespoke test harnesses, the startup logic can be
moved to `-[FlutterViewController awakeFromNib]` in a
FlutterViewController subclass.

An example can be seen here:

https://github.com/flutter/flutter/pull/169276/files#diff-dbe39c23a0a380447b90b7559a878dae8564616e0875c4ef0d9e99e02b91adac

## Changes since revert
I changed the init in `//dev/integration_tests/external_textures` from
the UIApplicationDelegate to the FlutterViewController's awakeFromNib.
This is a more appropriate place for initialization post-UISceneDelegate
since it avoids the launch engine altogether. I tried avoiding to make
the big change to prove we could do a small change to migrate that
project. I don't think this big refactor is indicative of what users
will experience. There was a timing assumption in the integration test
that required not using the launch engine at all.

Fix keyboard_hot_restart_ios flakes (#168518)
The keyboard hot restart test does these steps:

1. It launches an app that forces the keyboard to be visible
2. It checks that the keyboard is visible by examining the app's logs
3. It updates the app to no longer force the keyboard to be visible and
hot restarts the app
4. It checks that the keyboard is no longer visible by examining the
app's logs

Previously, the test app printed the keyboard status whenever the app
rebuilt. The test would move on as soon as it saw a log that indicates
the keyboard was in the expected state. However, since the app could log
the keyboard's visibility _before_ the Dart VM was available, hot
restart commands could be ignored (or at least, that's my theory from
the DeviceLab logs).

Now, the test app prints the keyboard status non-stop. The test now
waits until the Dart VM is available before checking if the logs
indicate the keyboard is open. Also, the test now waits until the hot
restart has completed before checking if the keyboard is closed. In
theory, this should ensure that hot restart does not happen until after
the Dart VM is available.

defaults for `BottomAppBar` properties.
- Added `BottomAppBarTheme` constructor parameters:
`BottomAppBarThemeData? data` and `Widget? child`. This is now the
preferred way to configure a `BottomAppBarTheme`:

```dart
BottomAppBarTheme(
	data: BottomAppBarThemeData(
	    color: xxx,
	    height: xxx,
	    elevation: xxx,
	    shape: xxx,
	    ...
	  ),
  	child: const BottomAppBar()
)
```
These two properties are made nullable to not break existing apps which
has customized `ThemeData.bottomAppBarTheme`.

- Update `BottomAppBarTheme` to be an `InheritedWidget` subclass.
- Changed the type of component theme defaults from `BottomAppBarTheme`
to `BottomAppBarThemeData`.
- Changed the `BottomAppBarTheme bottomAppBarTheme` property to
`BottomAppBarThemeData bottomAppBarTheme` in `ThemeData` and
`ThemeData.copyWith()`. This may cause breaking changes, a migration
guide will be created on website repo.
- Add new tests for `BottomAppBarThemeData` and update the existing
`BottomAppBarTheme` tests. And also turn to `true` for `useMaterial3`
(along with usages accordingly) at the common method `_withTheme()`
since `useMaterial3` is true by default.
- Addresses the "theme normalization" sub-project within #91772.

add missing lockfiles not checked in from running generate_gradle_lockfiles.dart (#168600)
<!--

These are generated files from using generate_gradle_lockfiles.dart
--no-gradle-generation

They require no unit tests but a follow up PR will address adding a CI
that tests if there are any lockfiles that need to be added.

Partially addresses #163228
