This PR is a follow-up of a previous PR of mine:
https://github.com/flutter/flutter/pull/141417. It was unfinished, i.e.
I only implemented it and used it in `examples/hello_world`. No "flutter
create" templates were modified.
This change is theoretically breaking, but in practice, I am pretty sure
nobody uses this. It was not accounced anywhere, the only app using it
is `examples/hello_world`. I did not do that (that=update docs and
templates) because I wanted a solution that is idiomatic in both Gradle
and Kotlin, and only now I found time to do this.
### Without this change
```groovy
defaultConfig {
applicationId = "io.flutter.examples.hello_world"
minSdk = flutter.minSdkVersion
targetSdk = flutter.targetSdkVersion
versionCode = flutter.versionCode()
versionName = flutter.versionName()
}
```
### With this change
```groovy
defaultConfig {
applicationId = "io.flutter.examples.hello_world"
minSdk = flutter.minSdkVersion
targetSdk = flutter.targetSdkVersion
versionCode = flutter.versionCode
versionName = flutter.versionName
}
```
Idiomatic getter - yay! It's consistent between assignment of all four
props.

* Updated the Material Design tokens to v2.3.5
* Linear and circular progress indicator token sets are deprecated in v0.207. The `md.com.progress-indicator` token set was created and should be used instead.
* tokens is now using [semantic versioning](https://semver.org/) ï¼Thanks @guidezpl for reminding:) )
* ~Fixes #128877. The default text style is updated to `bodyLarge` now:)~ Added TODOs for the label text style of `PopupMenuButton`. Will create a separate PR because this change breaks Google testing.
In order for text fields to work correctly in multi-view on the web, we need to have the `viewId` information sent to the engine (`TextInput.setClient`). And while the text field is active, if it somehow moves to a new `View`, we need to inform the engine about such change (`TextInput.updateConfig`).

This PR makes the static API of the `BackgroundIsolateBinaryMessenger` consistent between its web and IO implementations.
This way, multi-platform applications will compile for the web when using the `ensureInitialized` method (even though it'll throw at runtime, like the `instance` getter, because isolates are not supported on the web).

This PR is optimized for ease of implementation, and should not be merged as-is. If it is merged as-is, seriously consider creating a tech debt issue and assigning it to someone to make sure it gets resolved.
This PR expands the `HtmlElementView` widget DartDocs, with the following sections:
* Usage: How to use the widget, two ways:
* The `HtmlElementView.fromTagName` constructor
* The `PlatformViewRegistry` way
* Lifecycle: There's an `onCreated` callback on the widget. When does it get called?
* HTML Lifecycle: How to listen to events coming from the DOM.
* Visibility: what is the `isVisible` property for?
Small additional tweaks here and there to mention common pitfalls of using HtmlElementView on the web, and mentions to workarounds, like `package:pointer_interceptor`.

This pull request refactors if-statements into switch expressions, as part of the effort to solve issue #144903.
Making changes beyond just swapping syntax is more difficult (and also more difficult to review, I apologize), but much more satisfying too.
`@visibleForOverriding` + `@protected` unfortunately does not catch the case where a `compute*` method was overridden in a subtype and the overide was called in that same type's implementation.
I did not add a `flutter_ignore` for this because it doesn't seem there will be false positives.
## Description
This adds some "See also" links to some docs for `TweenAnimationBuilder` and `ValueListenableBuilder`.
Also, moved a "snippet" example in `ValueListenableBuilder` into the examples directory as a Dartpad example.
## Tests
- Added test for the example.
There are two issues in the previous implementation:
1. `_populateDevices` will return the devices from `deviceNotifier` if it had been initialized, assuming that once it's initialized, it has been properly populated. That assumption is not true because calling getters like `onAdded` would initialize `deviceNotifier` without populating it.
2. `deviceNotifier` instance might be replaced in some cases, causing `onAdded` subscribers to lose any future updates.
To fix (1), this commit added the `isPopulated` field in `deviceNotifier` as a more accurate flag to determine if we need to populate it.
To fix (2), this commit made `deviceNotifier` a final member in `PolingDeviceDiscovery`.
* Adds support for `flutter test --wasm`.
* The test compilation flow is a bit different now, so that it supports compilers other than DDC. Specifically, when we run a set of unit tests, we generate a "switchboard" main function that imports each unit test and runs the main function for a specific one based off of a value set by the JS bootstrapping code. This way, there is one compile step and the same compile output is invoked for each unit test file.
* Also, removes all references to `dart:html` from flutter/flutter.
* Adds CI steps for running the framework unit tests with dart2wasm+skwasm
* These steps are marked as `bringup: true`, so we don't know what kind of failures they will result in. Any failures they have will not block the tree at all yet while we're still in `bringup: true`. Once this PR is merged, I plan on looking at any failures and either fixing them or disabling them so we can get these CI steps running on presubmit.

This pull request introduces a new field named `helper` to the InputDecoration class. This field allows for specifying a widget containing contextual information about the InputDecorator.child's value. Unlike `helperText`, which accepts a plain string, `helper` supports widgets, enabling functionalities like tappable links for further explanation. This change aligns with the established pattern of `error`, `label`, `prefix`, and `suffix`.
fixes [#145163](https://github.com/flutter/flutter/issues/145163)
Pre work for https://github.com/flutter/engine/pull/51229. Removes a lot of code referencing v1 of the android embedding, though not necessarily all of it (I may have missed some, it is hard to know).
Will hopefully make landing that PR less painful (or maybe painless?)
A ProxiedDevice has two port forwarder, one to forward remote host port and another to forward remote device port. During an attach workflow, the port was forwarded by the latter. Update ProxiedDDS to make sure that it works in such case.
Fixes#138270.
Moves the majority of the logic of MaterialStateProperties down to the widgets layer, then has the existing Material classes pull from the widgets versions.
## Description
The PR updates `SingleActivator` in order to add a parameter for specifying that a shortcut depends on <kbd>NumLock</kbd> key state.
Somewhat similarly to what is possible with common modifiers expect that a boolean is not enough in this case because: by default, a shortcut should ignore the <kbd>NumLock</kbd> state and it should be possible to define shortcuts that require <kbd>NumLock</kbd> to be locked and other that require it to be unlocked.
@gspencergoog I considered defining a new `ShortcutActivator` implementation for this, but I thinks that adding the feature directly to `SingleActivator` results in a cleaner API.

## Tests
Adds 3 tests.
This manually rolls pub packages and updates some calls to use updated APIs that use `Uri` instead of file paths (since macro-generated sources don't exist as files on disk).
Use a dedicated `TextPainter` for intrinsic size calculation in `RenderEditable` and `RenderParagraph`.
This is an implementation detail so the change should be covered by existing tests. Performance wise this shouldn't be significantly slower since SkParagraph [caches the result of slower operations across different paragraphs](9c62e7b382/modules/skparagraph/src/ParagraphCache.cpp (L254-L272)). Existing benchmarks should be able to catch potential regressions (??).
The reason for making this change is to make sure that intrinsic size computations don't destroy text layout artifacts, so I can expose the text layout as a stream of immutable `TextLayout` objects, to signify other render objects that text-layout-dependent-cache (such as caches for `getBoxesForRange` which can be relatively slow to compute) should be invalidated and `markNeedsPaint` needs to be called if the painting logic depended on text layout.
Without this change, the intrinsics/dry layout calculations will add additional events to the text layout stream, which violates the "dry"/non-destructive contract.
This reverts commit 726e5d28c0.

In the past, my efforts to reduce line length involved refactoring away from switch statements, but unlike [yesterday's PR](https://github.com/flutter/flutter/pull/144905), this one is full of switch statements that make things more concise!
When a Sliver with items is outside of the Viewport, but within the Viewport's `cacheExtent`, the framework should create SemanticNodes for the items even though they are out of view. However, for this to work, the Sliver's geometry must have a `cacheExtent` (how much space the sliver took up of the Viewport's `cacheExtent`) greater than 0, otherwise it is [excluded](f01ce9f4cb/packages/flutter/lib/src/rendering/viewport.dart (L311-L315)).
`SliverFillRemaining` widgets that fall outside the viewport did not have this set and therefore were being excluded when SemanticNodes were created, even if they were within the Viewport's `cacheExtent`. This PR sets the `cacheExtent` for `SliverFillRemaining` widgets.
In addition, `RenderSliverFillRemainingWithScrollable` would get dropped from the semantic tree because it's child had a size of 0 when outside the remaining paint extent. To fix, we give the child a `maxExtent` of the sliver's `cacheExtent` if it's outside the remaining paint extent but within the viewport's cacheExtent.
Fixes https://github.com/flutter/flutter/issues/142065.
Definitions:
* `RenderViewport.cacheExtent`:
```dart
/// The viewport has an area before and after the visible area to cache items
/// that are about to become visible when the user scrolls.
///
/// Items that fall in this cache area are laid out even though they are not
/// (yet) visible on screen. The [cacheExtent] describes how many pixels
/// the cache area extends before the leading edge and after the trailing edge
/// of the viewport.
///
/// The total extent, which the viewport will try to cover with children, is
/// [cacheExtent] before the leading edge + extent of the main axis +
/// [cacheExtent] after the trailing edge.
///
/// The cache area is also used to implement implicit accessibility scrolling
/// on iOS: When the accessibility focus moves from an item in the visible
/// viewport to an invisible item in the cache area, the framework will bring
/// that item into view with an (implicit) scroll action.
```
* `SliverGeometry.cacheExtent`:
```dart
/// How many pixels the sliver has consumed in the
/// [SliverConstraints.remainingCacheExtent].
```
* `SliverContraints.remainingCacheExtent`:
```dart
/// Describes how much content the sliver should provide starting from the
/// [cacheOrigin].
///
/// Not all content in the [remainingCacheExtent] will be visible as some
/// of it might fall into the cache area of the viewport.
///
/// Each sliver should start laying out content at the [cacheOrigin] and
/// try to provide as much content as the [remainingCacheExtent] allows.
```
Fixes#38926
This patch implements the iOS behavior pointed out by @dkwingsmt at #38926 , which is also consistent with the performance of my settings application on the iPhone.
### iOS behavior (horizontal or vertical drag)
## Algorithm
When dragging: delta(combined) = max(i of n that are positive) delta(i) - max(i of n that are negative) delta(i)
It means that, if two fingers are moving +50 and +10 respectively, it will move +50; if they're moving at +50 and -10 respectively, it will move +40.

This makes several changes to flutter web app bootstrapping.
* The build now produces a `flutter_bootstrap.js` file.
* By default, this file does the basic streamlined startup of a flutter app with the service worker settings and no user configuration.
* The user can also put a `flutter_bootstrap.js` file in the `web` subdirectory in the project directory which can have whatever custom bootstrapping logic they'd like to write instead. This file is also templated, and can use any of the tokens that can be used with the `index.html` (with the exception of `{{flutter_bootstrap_js}}`, see below).
* Introduced a few new templating tokens for `index.html`:
* `{{flutter_js}}` => inlines the entirety of `flutter.js`
* `{{flutter_service_worker_version}}` => replaced directly by the service worker version. This can be used instead of the script that sets the `serviceWorkerVersion` local variable that we used to have by default.
* `{{flutter_bootstrap_js}}` => inlines the entirety of `flutter_bootstrap.js` (this token obviously doesn't apply to `flutter_bootstrap.js` itself).
* Changed `IndexHtml` to be called `WebTemplate` instead, since it is used for more than just the index.html now.
* We now emit warnings at build time for certain deprecated flows:
* Warn on the old service worker version pattern (i.e.`(const|var) serviceWorkerVersion = null`) and recommends using `{{flutter_service_worker_version}}` token instead
* Warn on use of `FlutterLoader.loadEntrypoint` and recommend using `FlutterLoader.load` instead
* Warn on manual loading of `flutter_service_worker.js`.
* The default `index.html` on `flutter create` now uses an async script tag with `flutter_bootstrap.js`.
Some tests are assuming the flutter sdk code is being checked out to flutter and checking the code to a different repository makes them fail.

Fixes#124850.
Changes the fallback for the builder on Android. Before the error was from the platform being changed mid Cupertino transition to iOS. If a default builder wasn't set for iOS (which a developer developing only for Android might not), then it defaulted to the Zoom transition. Which changing the transition while on the fly caused issues.
This fixes https://github.com/flutter/flutter/issues/143703
We need to make sure that when source maps are enabled for the dart2js target, it advertises the sourcemap file as one of its outputs so that the web release bundle can copy it over.
The flutter engine & framework can opt out of this optimization for
individual classes / class hierarchies via:
* `@pragma(flutter:keep-to-string)`
* `@pragma(flutter:keep-to-string-in-subtypes)`
Or by using the convenience constant `@keepToString` from `dart:ui`.

## Update `AlertDialog` Documentation for Material 3 Defaults
This pull request updates the documentation for `AlertDialog` to accurately reflect the default text styles (`titleTextStyle` and `contentTextStyle`) when using Material 3.
Previously, the documentation suggested default styles (`TextTheme.titleLarge` for titles and `TextTheme.titleMedium` for content) that do not align with Material 3 implementation, which uses `TextTheme.headlineSmall` and `TextTheme.bodyMedium` respectively.
Fixes#144489
Part of #137040 and #80374
The flag `throwOnPluginPubspecError` never actually was enabled during production in #79669, but only in some dart plugin tests. And in the tests the case of the error when enabling the flag was not explicitly tested. The only thing tested was, that it is not thrown when disabled.
As explained [here](https://github.com/flutter/flutter/pull/142035#discussion_r1484237904) the only case, where this error could be thrown is, when a dart implementation and a native inline implementation are provided simultaneously. But throwing an exception there is a wrong behavior, as both can coexist in a plugin package, thus in the pubspec file.
Disabling the flag means, that the error is not thrown and not shown to the user. This is the case in production (contrary to the dart plugin tests), which acts like these plugin cases of implementations are just skipped. And this is what actually should be done.
In conclusion, I think the case of coexisting dart and native implementation in pubspec was just overlooked and therefore this error validation was introduced, which is not necessary or even valid.

- This is tricky: I already added a test in #142035, which finally complies with the other tests, by removing the flag. So I think it falls in the category of "remove dead code".
- Theoretically this is a breaking change, as removing / altering some tests. But the flag actually was never valid or used, so IDK. But this may not does fall in the category of "contributed tests".
## Description
This PRs changes the default value for the `platform` parameter used to simulate key events.
With this PR, the default value is "web" on web, otherwise it is the operating system name retrieved from `defaultTargetPlatform`.
Previously, for methods in `WidgetController`, it defaulted to âwebâ on web, and âandroidâ everywhere else. And for methods in `KeyEventSimulator` it defaulted to âwebâ on web, and the operating system that the test was running on everywhere else. Because the operating system was based on `Platform.operatingSystem`, it usually differed from the target platform the test was running on.
AFAIK, the `platform` parameter is only meaningful for simulating `RawKeyEvent`. Once `RawKeyboard` will be fully removed, the `platform` parameter wonât be needed.
@gspencergoog In the meantime, do you think it is worth merging this fix?

## Description
This PRs changes the default value transit mode for key event simulation.
The default transit mode for key event simulation is currently `KeyDataTransitMode.rawKeyData` while on the framework side `KeyDataTransitMode.keyDataThenRawKeyData` is the preferred transit mode.
`KeyDataTransitMode.keyDataThenRawKeyData` is more accurate and can help detect issues.
For instance the following test will fail with `KeyDataTransitMode.rawKeyData` because raw keyboard logic for modifier keys is less accurate:
```dart
testWidgets('Press control left once', (WidgetTester tester) async {
debugKeyEventSimulatorTransitModeOverride = KeyDataTransitMode.keyDataThenRawKeyData;
final List<KeyEvent> events = <KeyEvent>[];
final FocusNode focusNode = FocusNode();
addTearDown(focusNode.dispose);
await tester.pumpWidget(
Focus(
focusNode: focusNode,
autofocus: true,
onKeyEvent: (_, KeyEvent event) {
events.add(event);
return KeyEventResult.handled;
},
child: Container(),
),
);
await simulateKeyDownEvent(LogicalKeyboardKey.controlLeft);
// This will fail when transit mode is KeyDataTransitMode.rawKeyData
// because a down event for controlRight is synthesized.
expect(events.length, 1);
debugKeyEventSimulatorTransitModeOverride = null;
});
```
And the following this test is ok with `KeyDataTransitMode.rawKeyData` but rightly fails with `KeyDataTransitMode.keyDataThenRawKeyData`:
```dart
testWidgets('Simulates consecutive key down events', (WidgetTester tester) async {
debugKeyEventSimulatorTransitModeOverride = KeyDataTransitMode.rawKeyData;
// Simulating several key down events without key up in between is tolerated
// when transit mode is KeyDataTransitMode.rawKeyData, it will trigger an
// assert on KeyDataTransitMode.keyDataThenRawKeyData.
await simulateKeyDownEvent(LogicalKeyboardKey.arrowDown);
await simulateKeyDownEvent(LogicalKeyboardKey.arrowDown);
debugKeyEventSimulatorTransitModeOverride = null;
});
```

## Tests
Adds two tests.
`DevFSBytesContent` (and it's descendant `DevFSStringContent`) have setters that change the underlying content. These are unused outside of tests, so this PR removes them. Amongst other things, this could help me refactor https://github.com/flutter/flutter/pull/144660 into something that has fewer pitfalls.
This is purely a refactoring.
We should always target the newest, and 34 is the newest. This isn't a requirement yet (like it is for 33+) but presumably it will be made required in the nearish future.
I was doing some debugging on a RenderSliver subclass, and found
that SliverConstraints.toString was missing the precedingScrollExtent
field.
Add that, and add both that field and userScrollDirection to the
`==` and hashCode implementations, which had been skipping them,
so that all three methods now handle all the class's fields.

This enables asset transformation during hot reload (except for web, because that has its own implementation of `DevFS` ð). Asset transformers will be reapplied after changing any asset and performing a hot reload during `flutter run`.
Explicitly handle the case where the iOS device is not paired. On `flutter run` show an error and bail instead of trying and failing to launch on the device.
On this PR:
```
$ flutter run -d 00008110-0009588C2651401E
'iPhone' is not paired. Open Xcode and trust this computer when prompted.

Originally, my aim was just to refactor (as per usual), but while messing around with the `TableBorder.symmetric` constructor, I realized that `borderRadius` was missing!
This pull request makes a few class constructors more efficient, and it fixes#144277 by adding the missing parameter.
