Towards https://github.com/flutter/flutter/issues/159000 as part of
debugging issues such as
https://github.com/flutter/flutter/issues/158560.
On a `bringup: true` shard, run a number of `flutter build apk` tests in
succession to try and routinely trigger timeouts and crashes, so we can
test other hypotheses on how to fix this problem (i.e. potentially
around increasing memory, changing daemon configuration, aggressively
killing processes, etc).
In the future, it will be possible for Swift Package Manager to be enabled on one but not all platforms (see https://github.com/flutter/flutter/issues/151567#issuecomment-2455941279).
This updates the `.flutter-plugin-dependencies` file format to separate iOS's and macOS's SwiftPM enablement. For now, these platforms will always have the same value.
This `.flutter-plugin-dependencies` file is read by our CocoaPods scripts to determine whether we should use CocoaPods or not to inject plugins.

**PR Title:**
Remove block and line comments when detecting `'.flutter-plugins'` in `settings.gradle`
---
**Description:**
This PR modifies the `configureLegacyPluginEachProjects` function to remove block (`/* ... */`) and line (`// ...`) comments from the `settings.gradle` or `settings.gradle.kts` file content before checking for the presence of the `'.flutter-plugins'` string. This ensures that only uncommented, meaningful code is considered during the detection, preventing false positives when the string appears within comments.
**Why is this change necessary?**
In some cases, the `'.flutter-plugins'` string may be present inside comments in the `settings.gradle` file. The existing implementation does not account for this and may incorrectly detect the string even when it's commented out. This can lead to unintended behavior, such as configuring plugin projects when it is not necessary.
By removing comments before performing the check, we prevent false positives and ensure that the detection logic is accurate, only acting when the `'.flutter-plugins'` string is present in active code.
**Changes Made:**
- **Added comment removal logic:**
- Removed block comments (`/* ... */`) using the regular expression `/(?s)\/\*.*?\*\//`.
- The `(?s)` flag enables dot-all mode, allowing `.` to match newline characters.
- Removed line comments (`// ...`) using the regular expression `/(?m)\/\/.*$`.
- The `(?m)` flag enables multi-line mode, so `^` and `$` match the start and end of each line.
- Combined both comment removal steps into a single chain for efficiency.
- **Updated the string detection:**
- The check for `'.flutter-plugins'` is now performed on the uncommented content of the `settings.gradle` file.
- This ensures that only meaningful, uncommented code is considered during detection.
**Issue Fixed:**
- Fixes [#155484](https://github.com/flutter/flutter/issues/155484)

The test was immediately checking the contents of stdout after the daemon indicated that the hot reload had completed. This could cause a race since the reloaded code may not have had time to execute.
Fixes https://github.com/flutter/flutter/issues/158245
Almost all of the code is just adopting to changes to the APIs of
`package:native_assets_builder`, `package:native_assets_cli` and
`package:native_toolchain_c`
There's only two semantic changes
* Removes a test that checks for a verification error if a build hook
produces a static library if the preferred linking mode is dynamic:
=> The test is written in a very hacky way. By monkey patching the build
config.json that flutter build actually made. This monkey patching
relies on package:cli_config which is now no longer used.
=> The actual code that checks for this mismatch lives in
dart-lang/native repository and is tested there. So there's really no
need to duplicate that.
* The `package:native_assets_builder` no longer knows about code assets.
This is something a user of that package (e.g. flutter tools) adds. Now
the dry-run functionality will invoke build hooks who produce code
assets without an architecture.
=> The `package:native_assets_builder` used to expand such a code asset
to N different code assets (one for each supported architecture)
=> This logic was now moved to flutter tools. => In the near future
we're going to this dry-run complexity, which will then also get rid of
this uglyness (of expanding to all archs of an OS).
Currently the bot that runs `flutter update-packages` makes PRs that
fail due to native asset integration tests failing.
The root cause is due to incompatible versions on `package:logging`. The
bot tries to upgrade `package:logging` from `1.2.0` to `1.3.0`.
Here's what seems to happen:
* `flutter update-packages` will update
`dev/integration_tests/link_hook/pubspec.yaml` with `package:logging` to
`1.3.0` (as it does with all other `pubspec.yaml` files in the flutter
repository)
* `flutter create --template=package_ffi` will generate a template with
`package:logging` `^1.2.0`
* The test in question
* creates ffi template (which will use `^1.2.0`)
* make it depend on `dev/integration_tests/link_hook` (which uses
`=1.3.0`)
* changes logging dependency from the template from `^1.2.0` to `=1.2.0`
IMHO
* `flutter update-packages` is doing what it's supposed to
* `flutter create --template=package_ffi` can generate templates with
versions it determines (maybe there are use cases where we want to
generate templates with older versions)
* The problematic part is the test:
* it makes the generated template depend on `link_hook` and
* changes template generated pubspec to use pinned dependencies
This PR makes the test package (created via template) use the pinned
package versions from `dev/integration_tests/link_hook` (for
dependencies that are common among the two).
All other dependencies that the template has on top of
`dev/integration_tests/link_hook` it can pin as it does currently.
This will give us deterministic CI behavior (as we use flutter pined
packages and remaining deps being pinned via template) It avoids
changing the `flutter update-packages` and `flutter create
--template=package_ffi` (as their behavior seems reasonable)
Should fix https://github.com/flutter/flutter/issues/158135
Closes https://github.com/flutter/flutter/issues/158120.
This PR restores the skipped test, moving it (and the test utility only used by the test) into a standalone file that can be more easily understood. As part of the change the version of `native_assets_cli` is now derived from the (checked-in) `package_ffi/pubspec.yaml.tmpl`, meaning that it should be hard to get into a bad state again.
/cc @christopherfujino (You are welcome to review, but otherwise will defer to Brandon and Victor).
Two of the tests, `test_test` and `break_on_framework_exceptions`, no longer appear to leak (without changes). Perhaps underlying infrastructure has changed, or some other bug in the tool itself was fixed in meantime.
`packages_test` required resetting `Cache.flutterRoot`.

There are two factors that hugely impact how easy it is to understand a piece of code: **verbosity** and **complexity**.
Reducing **verbosity** is important, because boilerplate makes a project more difficult to navigate. It also has a tendency to make one's eyes gloss over, and subtle typos/bugs become more likely to slip through.
Reducing **complexity** makes the code more accessible to more people. This is especially important for open-source projects like Flutter, where the code is read by those who make contributions, as well as others who read through source code as they debug their own projects.
<hr>
<br>
The following examples show how pattern-matching might affect these two factors:
<details> <summary><h3>Example 1 (GOOD)</h3> [click to expand]</summary>
```dart
if (ancestor case InheritedElement(:final InheritedTheme widget)) {
themes.add(widget);
}
```
Without using patterns, this might expand to
```dart
if (ancestor is InheritedElement) {
final InheritedWidget widget = ancestor.widget;
if (widget is InheritedTheme) {
themes.add(widget);
}
}
```
Had `ancestor` been a non-local variable, it would need to be "converted" as well:
```dart
final Element ancestor = this.ancestor;
if (ancestor is InheritedElement) {
final InheritedWidget inheritedWidget = ancestor.widget;
if (widget is InheritedTheme) {
themes.add(theme);
}
}
```
</details>
<details> <summary><h3>Example 2 (BAD) </h3> [click to expand]</summary>
```dart
if (widget case PreferredSizeWidget(preferredSize: Size(:final double height))) {
return height;
}
```
Assuming `widget` is a non-local variable, this would expand to:
```dart
final Widget widget = this.widget;
if (widget is PreferredSizeWidget) {
return widget.preferredSize.height;
}
```
<br>
</details>
In both of the examples above, an `if-case` statement simultaneously verifies that an object meets the specified criteria and performs a variable assignment accordingly.
But there are some differences: Example 2 uses a more deeply-nested pattern than Example 1 but makes fewer useful checks.
**Example 1:**
- checks that `ancestor` is an `InheritedElement`
- checks that the inherited element's `widget` is an `InheritedTheme`
**Example 2:**
- checks that `widget` is a `PreferredSizeWidget`
(every `PreferredSizeWidget` has a `size` field, and every `Size` has a `height` field)
<br>
<hr>
I feel hesitant to try presenting a set of cut-and-dry rules as to which scenarios should/shouldn't use pattern-matching, since there are an abundance of different types of patterns, and an abundance of different places where they might be used.
But hopefully the conversations we've had recently will help us converge toward a common intuition of how pattern-matching can best be utilized for improved readability.

Rolls native deps to the latest version, and cleans up deprecated field from template.
Tests:
* All the unit and integration tests for native assets. The template and dependencies are exercised in the integration test.
Since `package:native_assets_builder` already checks for having no static libraries as output, the custom check in flutter_tools is removed. The tests stubbing out the native assets builder exercising the custom check are also removed. (The integration tests now check for the error message from the native assets builder.)
Native libraries that are contributed by native asset builders can depend on each other. For macOS and iOS, native libraries are repackaged into Frameworks, which renders install names that have been written into dependent libraries invalid.
With this change, a mapping between old and new install names is maintained, and install names in dependent libraries are rewritten as a final step.

The stream subscriptions in the device's VmService are used by other parts of FlutterVmService and other components throughout flutter_tools. Components that listen to streams should not call VmService.streamCancel because that will interfere with other users who still want the events.

When DevTools is active HotRunner.attach makes a deferred RPC to a DevTools service. That RPC appears to cause issues if it executes at the wrong time during the hot restart.

The point of this test is that you can see the error `int x = 'String';` error in the tool output. https://github.com/flutter/flutter/issues/72608#issuecomment-797473109
I think just updating the test to check stderr or stdout is sufficient without touching the tool behavior.

If Swift Package Manager is enabled, the tool generates a Swift package at `<ios/macos>/Flutter/ephemeral/Packages/FlutterGeneratedPluginSwiftPackage/`. This Swift package is how the tool adds plugins to the Flutter project.
SwiftPM is strictly enforces platform versions: you cannot depend on a Swift package if its supported version is higher than your own.
On iOS, we use the project's minimum deployment version for the generated Swift package. If a plugin has a higher requirement, you'll need to update your project's minimum deployment version. The generated Swift package is automatically updated the next time you run the tool.
This updates macOS to do the same thing.

Updates the expected steps in the async function defined within `stepping_project.dart`.
The Dart web team is updating the async semantics of DDC to bring them in line with the other backends. Currently, the DDC async semantics don't adhere to the Dart spec and this can lead to inconsistent and surprising results.
However, the step-over operation doesn't work well yet with the new DDC async semantics. In the long run we intend to improve this but until then the debug stepper will have sporadic results that we can't model well with this test. When we are able to fix the stepper functionality, we will return this test to cover more of the async function being stepped over.
When the `"${native_assets_path}"*.framework` glob doesn't resolve anything, the bash will run the loop once with the original unglobbed value: `/path/to/native/assets/*.framework`. Skip this case to prevent the build from failing when there are no frameworks to sign.
To reproduce this build failure:
1. Enable native assets in the Flutter tool: `flutter config --enable-native-assets`
2. Create a Flutter project with the default template: `flutter create test_native_assets`
3. Add a build hook that does nothing (`hook/build.dart`).
4. Try to build/run the app: `flutter run --debug -d macos`
This changes the mapping for the Dart SDK inside Flutter from `org-dartlang-sdk:///third_party/dart/sdk` to org-dartlang-sdk:///flutter/third_party/dart/sdk`. This URI changed in https://github.com/flutter/engine/pull/51917 but was not caught by tests because they only tested a specific set of mappings and there were no integration tests checking what URIs were actually produced by a running app.
So, this change also adds an integration tests that ensures that a real running app produces URIs that are then correctly mapped.
Fixes https://github.com/Dart-Code/Dart-Code/issues/5164.
