fix https://github.com/flutter/flutter/issues/121493
`SegmentedButton` uses `TextButton` for each segments. When we have `MaterialTapTargetSize.padded` for `TextButton`, we make sure the minimum tap target size is 48.0( this value can be adjusted by visual density), even tough the actual button size is smaller. When `SegmentedButton` paints segments by using `MultiChildRenderObjectWidget`, it also includes the tap target size so the button that it actually draws always has the same height as the height of the tap target size.
To fix it, this PR firstly calculate the actual height of a text button in `SegmentedButton` class, then we can get the height delta if there is. Then the the value of (Segmented button render box height - the delta) would be the actual button size that we should see.
For now, we are not able to customize the min, max, fixed size in [`SegmentedButton` style](https://api.flutter.dev/flutter/material/SegmentedButton/style.html). So the standard button height is always 40 and can only be customized by `style.visualDensity` and `style.tapTargetSize`; `SegmentedButton` only simulates the `TextButton` behavior when `TextButton`'s height is its default value.

It's now possible to natively compile a flutter app for windows-arm64. Cross-compilation is not yet implemented.
Uses arm64 artifacts now available for Dart/Flutter. Platform detection is based on Abi class, provided by Dart. Depending if Dart is an arm64 or x64 binary, the Abi is set accordingly. Initial bootstrap of dart artifacts (update_dart_sdk.ps1) is checking PROCESSOR_ARCHITECTURE environment variable, which is the way to detect host architecture on Windows.
This is available only for master channel (on other channels, it fallbacks to windows-x64).
On windows-x64, it produces an x64 app. On windows-arm64, it produces an arm64 app.

Part of work on [#101077](https://github.com/flutter/flutter/pull/141194). This is done as a separate PR to avoid a massive diff.
## Context
1. The `FakeCommand` class accepts a list of patterns that's used to match a command given to its `FakeProcessManager`. Since `FakeCommand` can match a list of patterns, not just specifically strings, it can be used to match commands where the exact value of some arguments can't (easily) known ahead of time. For example, a part of the tool may invoke a command with an argument that is the path of a temporarily file that has a randomly-generated basename.
2. The `FakeCommand` class provides on `onRun` parameter, which is a callback that is run when the `FakeProcessManager` runs a command that matches the `FakeCommand` in question.
## Issue
In the event that a `FakeCommand` is constructed using patterns, the test code can't know the exact values used for arguments in the command. This PR proposes changing the type of `onRun` from `VoidCallback?` to `void Function(List<String>)?`. When run, the value `List<String>` parameter will be the full command that the `FakeCommand` matched.
Example:
```dart
FakeCommand(
command: <Pattern>[
artifacts.getArtifactPath(Artifact.engineDartBinary),
'run',
'vector_graphics_compiler',
RegExp(r'--input=/.*\.temp'),
RegExp(r'--output=/.*\.temp'),
],
onRun: (List<String> command) {
final outputPath = (() {
// code to parse `--output` from `command`
})();
testFileSystem.file(outputPath).createSync(recursive: true);
},
)
```
This PR adds a test that reproduces the problem described in the linked issue: hot restart on the web seems to not update if the app being run is `const`.
The new test is expected to fail, until the `const` issue with hot restart in the web is resolved.
Expected failure mode is a 15s timeout in the following test:
```
02:31 +3 ~1 -1: Hot reload (index.html: Default) (with `const MyApp()`)): newly added code executes during hot restart [E]
TimeoutException after 0:00:15.000000: Future not completed
dart:async _startMicrotaskLoop
...
```
(And then a bunch of output that I'm not 100% sure is intended :))
## Issues
* #141588
Fixes#129590
* Consider `AxisDirection` when calculating scroll offset used in determining TextSelection during a drag/long press drag. Previously it seems that we were assuming the direction was always vertical 30cc831985/packages/flutter/lib/src/widgets/text_selection.dart (L2842-L2844) .
* SelectableText now considers RenderEditable offset changes and Scrollable offset changes when calculating the TextSelection during a long press drag.
Much of the new wording here is borrowed from [ChipTheme], [SliderTheme], or [RadioThemeData], which I think are pretty good. I believe a lot of other theme classes have similar wording too. I've also made some tweaks of my own, notably the references to [MaterialApp.theme].
This started from a desire to have clearer cross-references pointing at what to do with a FooThemeData to make it take effect:
https://github.com/flutter/flutter/pull/135879#discussion_r1355851481
but then as I started writing I kept finding more and more small things I wanted to adjust, including a couple of bits that were extraneous or obsolete.
Part of work on https://github.com/flutter/flutter/pull/141194
The [`AssetBundle`](0833929c99/packages/flutter_tools/lib/src/asset.dart (L80)) class contains two members, `entries` and `entryKinds`. `entries` contains asset data indexed by asset key. `entryKinds` contains the "kinds" of these assets, again indexed by asset key.
**Change.** Rather than have two separate maps, this PR proposes combining these maps into one by wrapping the asset data and kind into a single data type `AssetBundleEntry`.
**Purpose.** In https://github.com/flutter/flutter/pull/141194, I am considering associating more information with an asset. In particular, what transformers are meant to be applied to it when copying it to the build output. Rather than adding another map member onto `AssetBundle` (e.g. `entryTransformers`), I decided to make things neater by introducing the `AssetBundleEntry` type.
Fixes#141347
This PR is to add a "clear text" tooltip for the clear button on `SearchAnchor`'s search view and also add a `clearButtonTooltip` entry for `material_localizations`.
This is part 2 of a broken down version of the #140101 refactor.
This particular change wasn't in that original refactor but is a note to myself so that I remember how to test each of these changes in the future.

This PR introduces the first app in this repo that fully uses Gradle Kotlin DSL.

## Description
This removes an unneeded expectation in the test for the AppLifecycleListener. It's unneeded because the test immediately resets the state anyhow. I'm removing it because the web implementation sets the value when initializing, so it's never initially null there.

It's confusing that `debugPrint` also prints in release mode, given that a lot (most?) other things prefixed with `debug` don't do anything in release mode. Therefore, this adds some documentation that this is indeed logging in release mode and adds an example how to disable this.
*If you had to change anything in the [flutter/tests] repo, include a link to the migration guide as per the [breaking change policy].*
When a `TextField` is rendered before a `Navigator`, it breaks in semantics mode. This is because the framework generates the incorrect semantics tree (excludes the TextField) and when that tree gets sent to the engine, we don't get the signal to create the corresponding `<input>` element.
This happens for a few reasons:
* `ModalBarrier` uses `BlockSemantics` to drop the semantics of routes beneath the current route in `Navigator`
* `ModalBarrier` mistakenly recognizes the widget outside of the `Navigator` to be its sibling
* So we end up dropping the semantics node of the `TextField` rendered before it.
The fix is to let `Navigator` generate a semantics node so that `ModalBarrier` doesn't mistakenly think widgets outside of `Navigator` are its siblings.
`Navigator` doesn't currently do this, which causes all the nodes generated from its widget subtree to be directly attached to the parent semantics node above `Navigator` - since this is also the parent of `TextField`, it considers them siblings.

This PR adds the Dart VM `vm:platform-const-if` pragma introduced in
https://github.com/dart-lang/sdk/commit/57a1168875 to the
`defaultTargetPlatform` property, allowing it to be computed as if it
was a constant field in non-debug AOT builds. In particular, this means
that platform-specific code executed conditionally based on this
property can be tree-shaken in release builds. Note that this PR changes
`defaultTargetPlatform` to only allow overriding via
`debugDefaultTargetPlatformOverride` in debug builds, and makes it so
that compilation throws an error if code assigns
to`debugDefaultTargetPlatformOverride` in other build modes.

Rolls the packages from https://github.com/dart-lang/native in the native assets implementation.
Most notable we're refactoring `package:native_assets_cli` for `build.dart` use.
Therefore, all imports to that package for Flutter/Dart should be to the implementation internals that are no longer visible for `build.dart` writers. Hence all the import updates.
No behavior in Flutter apps should change.
This PR also updates the template to use the latests version of `package:native_assets_cli` which no longer exposes all the implementation details.
On `Podfile`:
```ruby
flutter_application_path = '../flutter_module'
load File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')
target 'OCProject' do
# Comment the next line if you don't want to use dynamic frameworks
use_frameworks!
# Pods for OCProject
# install_all_flutter_pods(flutter_application_path)
# install_flutter_engine_pod(flutter_application_path)
# install_flutter_application_pod(flutter_application_path)
install_flutter_plugin_pods(flutter_application_path)
end
post_install do |installer|
flutter_post_install(installer)
end
```
Encountering the following error after executing `pod install`:
```shell
pod install
[!] Invalid `Podfile` file: undefined method `flutter_relative_path_from_podfile' for #<Pod::Podfile:0x000000010e74c520 @defined_in_file=#<Pathname:/Users/lxf/gitHub/flutter_hybrid_bug/OCProject/Podfile>, @internal_hash={}, @root_target_definitions=[#<Pod::Podfile::TargetDefinition label=Pods>], @current_target_definition=#<Pod::Podfile::TargetDefinition label=Pods>>

#
# -------------------------------------------
```
The `flutter_relative_path_from_podfile` method is in `flutter_tools/bin/podhelper.rb`, but now `flutter_tools/bin/podhelper.rb` is only required in `install_all_flutter_pods` in `podhelper.rb.tmpl`.
Sometimes we only need to use the `install_flutter_plugin_pods` method in podhelper.rb. For example, using `Shorebird` in an iOS hybird app scenario, we need to build `Flutter.xcframework` and `App.xcframework` and embed them into the iOS native project. In order to avoid unnecessary conflicts, use `install_flutter_plugin_pods` method to install Flutter plugin pods.
[Shorebird - Code Push In Hybrid Apps](https://docs.shorebird.dev/guides/hybrid-app/ios)
So I adjust the position of `require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)`.
Remove more `textScaleFactor` references from flutter/flutter.
- Some changes are related to label scaling: the padding EdgeInsets values of some chip subclasses scale linearly between predetermined "max" padding values and "min" padding values. Before they scale with the `textScaleFactor` scalar, now they scale with the font size and are still capped at the original "max" and "min" values.
- The rest of them are tests or size heuristics that depend on `textScaleFactor`, these are replaced by an effective text scale factor computed using a default font size (which is determined in a pretty random fashion, but it will only make a difference on Android 14+).
No API changes in this batch. There are still some references left that I intend to remove in a different batch that would introduce API changes.

Much nicer calling API and simplifies evolving this API in the future.
I wish we could write a dart fix for this, but that's blocked on https://github.com/dart-lang/sdk/issues/54668.
The old doc says that, AutomatedTestWidgetsFlutterBinding for `flutter test` and LiveTestWidgetsFlutterBinding for `flutter run`. However, suppose we `flutter test integration_test/simple_test.dart` with the following code:
```
void main() {
testWidgets('hi', (WidgetTester tester) async {
print('hi ${TestWidgetsFlutterBinding.instance} ${Platform.operatingSystem}');
});
}
```
We will see: `hi <IntegrationTestWidgetsFlutterBinding> ios`. Therefore, we see `IntegrationTestWidgetsFlutterBinding` is used in a `flutter test` command, which is contrary to the documentation.
Includes the Engine roll from
https://github.com/flutter/flutter/pull/141841
A new version of Dart is having trouble with the tool integration test
test `passing one file with errors are detected`:
https://ci.chromium.org/ui/p/flutter/builders/try/Mac%20tool_integration_tests_2_4/31851/overview.
However the analysis server emits the expected errors when we give it
both the file without issues and the file with issues.
My guess is that the analysis server has changed it's behavior slightly
when supplied with a single malformed file.
Since the Dart roll is >20 dev versions behind, and this is the only
failing presubmit test, and it's testing something a bit weird, I
suggest we investigate the right way to test the thing that test was
attempting to cover as a follow-up.
- Unskip `text_style_test` for CanvasKit.
- Remove no longer necessary `kIsWeb` checks in a few tests.
This PR depends on https://github.com/flutter/engine/pull/49786, which rolled into the framework. If the engine PR needs to be reverted, this PR will need to be reverted too.
This PR improves the distance between the label and the icon in the Tab widget.
I updated the margin to 2 pixels, taken from the Figma design page for Material 3. On Material 2 I left the default value of 10 pixels.
Related to #128696 (In particular, the distance between label and icon)
Here are some screenshots for comparison. I looked a bit into the other mentioned issue of the tab height not following the M3 spec. Flutter uses 72 and the spec uses 64. But because Tab is a PreferredSizeWidget, I don't think there is an easy way to provide a different size depending on `ThemeData.useMaterial3`, because there is no `BuildContext` available.
I provide a sample image for the 64 height as well for context on the linked issue, even though it's not part of the PR changes.
The screenshots are taken side by side with the image at: https://m3.material.io/components/tabs/guidelines

## Summary
This PR makes public fields of `FlutterExtension` non-static. The aim is to make migrating from Gradle Groovy DSL to Gradle Kotlin DSL easier for Flutter developers, because...
### Without this PR
**android/app/build.gradle.kts**
```kotlin
plugins {
id "com.android.application"
id "dev.flutter.flutter-gradle-plugin"
}
android {
namespace = "io.flutter.examples.hello_world"
compileSdk = FlutterExtension.compileSdkVersion
defaultConfig {
applicationId = "io.flutter.examples.hello_world"
minSdk = FlutterExtension.minSdkVersion
targetSdk = FlutterExtension.targetSdkVersion
// ...
}
}
// ...
```
Groovy and Java allow accessing static fields of a class through its instance, but Kotlin is being more "correct" and disallows that.
### With this PR
Thanks to this PR, the user won't have to replace `flutter` with FlutterExtension in some places, thus decreasing possible confusion.

### After
This should wait for some upstream work, just don't want to lose it locally for now. I'll switch this from draft and update the description when it's ready.
While working in https://pub.dev/packages/two_dimensional_scrollables, I found I could eliminate some casts if we added covariants here in the framework.
Much of the 2D aPI in the framework is abstract, so I think it make sense to add these and make it easier/cleaner for subclasses using the APIs.
I made a similar change in https://github.com/flutter/flutter/pull/131358, this would cover all of the cases I could find so its nice and accommodating now.
This PR fixes scrolling issues with `NestedScrollView` using the `BouncingScrollPhysics`. In one of the steps of the calculation, we can reach a state where the position of the inner scrollable is set to a `double` value that falls within `precisionErrorTolerance` of `0` but we were using `==` with `0` rather than checking for a precision. My posts in the linked issue show the current behavior, and how I reached to conclusion (the code in this PR). This PR only addresses the "jumping" of the outer scrollable.
Fixes#136199
I have not finished a test for this since I have never done so and therefore have 0 experience writing tests in Flutter, so any help there would be appreciated. I am also not sure how to test double precision errors in general. I did run all the nested_scroll_view_tests.dart locally and there are no failures.
Fixes#141140.
This ensures that if you call `.copyWith` and pass a `debugLabel`, the `debugLabel` won't be ignored, even if the receiver (the TextStyle you're calling `.copyWith` on) doesn't have a `debugLabel`.
The debugLabel field was added in #12552. I skimmed the discussion there and didn't find anything indicating that the param was being ignored on purpose.
I added a test case that passes with the new code and fails with the old code.

dpr of 1.912500023841858. Flutter would translate that to a logical size
of 527.0588169589221 x 1149.2810314243163 and use that as the input for
its layout algorithm. Since the constraints here are tight, the layout
algorithm would determine that the resulting logical size of the root
render object must be 527.0588169589221 x 1149.2810314243163.
Translating this back to physical pixels by applying the dpr resulted in
a physical size of 1007.9999999999999 x 2198.0 for the frame. Android
now rejected that frame because it didn't match the expected size of
1008.0 x 2198.0 and since no frame had been rendered would never take
down the splash screen.
Prior to dynamically sized views, this wasn't an issue because we would
hard-code the frame size to whatever the requested size was.
Changes in this PR over the original PR:
* The issue has been fixed now by constraining the calculated physical
size to the input physical constraints which makes sure that we always
end up with a size that is acceptable to the operating system.
* The `ViewConfiguration` was refactored to use the slightly more
convenient `BoxConstraints` over the `ViewConstraints` to represent
constraints. Both essentially represent the same thing, but
`BoxConstraints` are more powerful and we avoid a couple of translations
between the two by translating the` ViewConstraints` from the
`FlutterView` to `BoxConstraints` directly when the `ViewConfiguration`
is created.
All changes over the original PR are contained in the second commit of
this PR.

(#139572) I would like to request an update to the document to resolve confusion.
I actually modified the code by applying priority as in the comment in [#139572](https://github.com/flutter/flutter/issues/139572) as shown below, but I thought that if 'OutlinedBorder' was used for 'shape', the default value of side for 'OutlinedBorder' was also the developer's intention.
```
OutlinedBorder _getShape(ThemeData theme, ChipThemeData chipTheme, ChipThemeData chipDefaults) {
final BorderSide? resolvedSide =
MaterialStateProperty.resolveAs<BorderSide?>(widget.side, materialStates)
?? MaterialStateProperty.resolveAs<BorderSide?>(chipTheme.side, materialStates);
final BorderSide? resolvedShapeSide =
MaterialStateProperty.resolveAs<BorderSide?>(widget.shape?.side, materialStates)
?? MaterialStateProperty.resolveAs<BorderSide?>(chipTheme.shape?.side, materialStates);
final OutlinedBorder resolvedShape =
MaterialStateProperty.resolveAs<OutlinedBorder?>(widget.shape, materialStates)
?? MaterialStateProperty.resolveAs<OutlinedBorder?>( chipTheme.shape, materialStates)
?? MaterialStateProperty.resolveAs<OutlinedBorder?>(chipDefaults.shape, materialStates)
// TODO(tahatesser): Remove this fallback when Material 2 is deprecated.
?? const StadiumBorder();
// If the side is provided, shape uses the provided side.
if (resolvedSide != null) {
return resolvedShape.copyWith(side: resolvedSide);
}
if (resolvedShapeSide != null) {
return resolvedShape.copyWith(side: resolvedShapeSide);
}
// If the side is not provided
// then the shape's side is used. Otherwise, the default side is used.
return resolvedShape.copyWith(side: chipDefaults.side);
}
```
(in `chip.dart`)
However, (#133856) PR seems to be intended to ignore this and use the aspect of `chipDefault.side` even if the developer specifies `shape.side` as [Border.none] without explicitly applying `side` .
This is probably because the default value of OutlinedBorder is [Border.none].
I think this is an area that can cause enough confusion, but there are a lot of things that need to be modified to reduce confusion through code changes, and the impact on existing code is likely to be significant.
I also confirmed that this is not accurately explained in the API Docs.
So rather than modifying the code, I decided to add additional explanation to the `shape` comment.
If the results are different from what you intended or the updated content is strange, please review. ð
Changes drag release logic so that an armed refresh is only canceled if the user has scrolled back up beyond the point where the refresh indicator was armed. (Fixes https://github.com/flutter/flutter/issues/138848.)
This is the minimal change I found could be made to restore something like the behavior that I would expect.
This may still need a bit of work, because it only masks the second issue I mentioned, that releasing a drag can cause the scroll position to be animated back up from the release point. There is actually a bug about that: https://github.com/flutter/flutter/issues/6052. I would like to see that bug fixed too. This PR doesn't address that, but makes it harder to hit that issue.
@Piinks this is a recreation of #139015 (since I couldn't figure out some issue with a git detached branch, so I fixed the PR and I'm re-submitting it). This version includes one line that was somehow accidentally dropped from the original PR. This will hopefully fix the test failures.
However, I don't have a clue how to write a test for a Flutter UI widget. I'll try to figure that out, but also I don't have a lot of time to work on this. I would appreciate at least some user testing to verify that the new behavior is much more intuitive than the old behavior.

Currently podhelper.rb will always point plugin builds at the cached engine artifacts, even when using `--local-engine`. In most cases this is fine, since when the final build actually runs it will be using the engine bundled into the app build, which will be the correct local engine build. When trying to test a local engine build with API additions against a local plugin modified to use those additions to ensure that they are working as expected, however, compilation will fail, because the new APIs won't be present in the plugin build.
This fixes that for macOS, and adds a TODO for iOS (which is more complicated to fix due to the host vs target build distinction).

Change the following in the `flutter create` templates. I didn't make any auto-migrations for existing apps because none seem that critical:
1. Turn on `ASSETCATALOG_COMPILER_GENERATE_SWIFT_ASSET_SYMBOL_EXTENSIONS` in iOS and macOS.
1. Turn on `BuildIndependentTargetsInParallel` in macOS template. https://github.com/flutter/flutter/pull/125827/files#r1181817619
1. Turn on `DEAD_CODE_STRIPPING` in macOS template.
1. Set `ENABLE_USER_SCRIPT_SANDBOXING=NO` in iOS and macOS template. `flutter` scripts don't work with this on. This might require a migration in the future to explicitly turn this one off. However at least for now if the setting isn't present it defaults to `NO`.
Add migration for `LastUpgradeVersion` so users won't see these validation issues in Xcode.
Run migrator on all the example apps. A few aren't Flutter apps so I edited them in Xcode.

SegmentedButtom.styleFrom has been added to the segment button, so there is no longer any need to the button style from the beginning. It works like ElevatedButton.styleFrom only I added selectedForegroundColor, selectedBackgroundColor. In this way, the user will be able to change the color first without checking the MaterialState states. I added tests of the same controls.
#129215 I opened this problem myself, but I was rejected because I handled too many items in a PR. For now, I wrote a structure that only handles MaterialStates instead of users.

Fixes https://github.com/flutter/flutter/issues/140665 by replacing use of `setUpAll` and `teardownAll` with `setUp` and `teardown` respectively.
My theory has to how this issue happened (and how this PR fixes it) is that `setUpAll` is not guaranteed to run after any `setUp` in any parent test groups. However, `setUp` is guaranteed to run after any set-up callbacks in parent groups. From the [documentation](https://api.flutter.dev/flutter/flutter_test/setUp.html):
> If this is called within a test group, it applies only to tests in that group. The body will be run after any set-up callbacks in parent groups or at the top level.
Meanwhile, [`setUpAll`](https://api.flutter.dev/flutter/flutter_test/setUpAll.html) has a weaker documented guarantee that applies only to other `setUpAll` calls:
> If this is called within a test group, The body will run before all tests in that group. It will be run after any [setUpAll](https://api.flutter.dev/flutter/flutter_test/setUpAll.html) callbacks in parent groups or at the top level. It won't be run if none of the tests in the group are run.

Currently the method we use for text span hit testing `TextPainter.getPositionForOffset` always returns the closest `TextPosition`, even when the given offset is far away from the text.
The new TextPaintes method tells you the layout bounds `(width = letterspacing / 2 + x_advance + letterspacing / 2, height = font ascent + font descent)` of a character, the PR changes the hit testing implementation such that a TextSpan is only considered hit if the point-down event landed in one of its character's layout bounds.
Potential issues:
In theory since the text is baseline aligned, we should use the max ascent and max descent of each character to calculate the height of the text span's hit-test region, in case some characters in the span have to fall back to a different font, but that will be slower and it typically doesn't make a huge difference.
This is a breaking change.

I want to build a widget that adds some extra functionality when the inner text overflow. So the problem occurred, I can't find an elegant way to determine if the text is overflowing.
So i expose `didExceedMaxLines` from `RenderParagraph`, I think it can make sense. Have there some advice?

**As a follow up to https://github.com/flutter/flutter/pull/131776.**
**Summary:**
Previously in https://github.com/flutter/flutter/pull/106561, SendTextInputAction was added to Flutter Driver.
But it still cannot be used from flutter_driver tests. This PR intends to resolve that issue.
**Issue:**
An `DriverError: Unsupported command kind send_text_input_action` would be thrown from `flutter_driver/lib/src/common/deserialization_factory.dart` when a call to `driver.sendTextInputAction(TextInputAction.done);` was made despite the method `sendTextInputAction` is available for use since https://github.com/flutter/flutter/pull/106561.
Previous works has been done in https://github.com/flutter/flutter/pull/131776, I merely added tests.
Best regards.
Relands #97823
When the tool migrated to `.flutter-plugins-dependencies`, the Gradle plugin was never changed.
Until now, the plugin had the heuristic that a plugin with a `android/build.gradle` file supported the Android platform.
Also applies schema of `getPluginDependencies` to `getPluginList` which uses a `List` of Object instead of `Properties`.
Fixes#97729
Cause of the error: 5f105a6ca7/packages/flutter_tools/gradle/flutter.gradle (L421C25-L421C25)Fixes#98048
The deprecated line `include ":$name"` in `settings.gradle` (pluginEach) in old projects causes the `project.rootProject.findProject` to also find the plugin "project", so it is not failing on the `afterEvaluate` method. But the plugin shouldn't be included in the first place as it fails with `Could not find method implementation() for arguments` error in special cases.

Fixes https://github.com/flutter/flutter/issues/131435, #104594, #43400
Needs https://github.com/flutter/engine/pull/48774 (to fix the web test failure).
Currently the method we use for text span hit testing `TextPainter.getPositionForOffset` always returns the closest `TextPosition`, even when the given offset is far away from the text.

This is a breaking change. It also introduces a new finder and a new method `WidgetTester.tapOnText`: `await tester.tapOnText('string to match')` for ease of migration.

This adds a static helper method `ProcessUtils.writelnToStdinGuarded()`, which will asynchronously write to a sub-process's STDIN `IOSink` and catch errors.
In talking with Brian, it sounds like this is the best and most reliable way to catch `SocketException`s during these writes *to sub-process file descriptors* specifically (with a "real" hard drive file, the future returned by `.flush()` should complete with the write error).
Also, as I note in the dartdoc to `writelnToStdinGuarded()`, the behavior seems to be different between macOS and linux.
Moving forward, in any place where we want to catch exceptions writing to STDIN, we will want to use this new helper.
