On Windows, Process.run assumes the output uses the system codepage by default. This allows specifying it in our wrapper, and sets the encoding for vswhere to UTF-8 since we're passing a flag that forces it to use UTF-8 output.

Fixes #53515

This makes the flutter and dart scripts invoke their batch file equivalents if running under MINGW (i.e. git-bash) on Windows.

This allows for proper locking, and makes sure that people aren't using two different (and non-mutally-aware) locking systems when running flutter on Windows.

I also fixed a couple of places where we look for MINGW32, which fails under MINGW64. It just looks for MINGW now.

Some of the null-safety commands were missing - plumb them through. Ensure that verbose mode shows their output, and clean up the messaging around sound-null-safety.

Fixes #59769

Adds a test that validate each of the null safety supporting build commands has everything plumbed through.

The addition of the non-optional parent logger broke the google3 roll. Make it optional so we can roll

The tool needs to start outputing trace text to stderr to avoid breaking machine mode. This test is bogus, and should use the exit code.

https://github.com/dart-lang/coverage - 0.14.0 added the ability to be able to ignore coverage depending on comments.

// coverage:ignore-line to ignore one line.
// coverage:ignore-start and // coverage:ignore-end to ignore range of lines inclusive.
// coverage:ignore-file to ignore the whole file.

Refactors KernelCompiler and ResidentCompiler to no longer use globals (except as a fallback for g3 migration). Improves the compilation error when running flutter test on a package without a flutter_test dependency.

Updates machine mode to output trace text to stderr

A frequent request from the last Flutter developer survey was for an easier method of testing light/dark mode changes. Currently, a user needs to manually change the theme settings or adjust phone settings to see the difference. Instead we should add a toggle from the CLI, and eventually devtools/Intellij/Vscode that allows developers to override the current setting.

Fixes #59495

Adds flutter.ext.brightnessOverride service protocol which either queries the current platform brightness, or overrides it to a new value. This accepts either Brightness.light or Brightness.dark as a value.

Adds a CLI toggle b which allows the setting to be toggled manually.

Requires an update to the MediaQuery, to conditionally use a debug override when not in release mode

Remove dependency on package:collection by moving mergeSort into foundation/collections.dart (#59521)

This removes a dependency from Flutter (package:collection) by copying the implementation of mergeSort into Flutter's foundation/collections.dart.

Also, removed a reference to UnmodifiableSetView from the shortcuts code by just returning a copy instead.

After Dart VM change we are now required to use loadLibrary on an import whenever it is imported as deferred.

See: https://dart-review.googlesource.com/c/sdk/+/149613

Updates the tooling to use the GTK embedding, rather than the GLFW embedding:
- Adds new requirements to `doctor`
- Updates the app and plugin templates to make GTK-based runners and plugins
- Stops downloading and installing the GLFW artifacts

Final part of #54860, other than cleanup.

This command was previously used by the re-entrant build scripts in xcode_backend.sh and build.gradle. These have since been refactored to use flutter assemble.

Deprecation the command in preparation for removal in a future release of flutter. The only current use is a test on HHH

This will need to be moved, so we can skip for now to avoid issues around double uploading or changing the token config. The tool coverage is fairly steady and we're not losing any historical data.
