This change removes uses of toString transformer from Flutter engine. The transformer is already wired up in Dart SDK: front-end server from Dart SDK supports --delete-tostring-package-uri option. After this change only the integration test is left in the Flutter engine to make sure dart:ui is properly transformed.
dart-lang/sdk#46022
This change prepares Flutter front-end server to the migration of --delete-tostring-package-uri option to Dart SDK. This is needed to call toString transformation before tree shaking.
dart-lang/sdk#46022
Add copyright headers in a few files where they were missing.
Trim trailing blank comment line where present, for consistency with
other engine code.
Use the standard libtxt copyright header in one file where it differed
(extra (C) and comma compared to other files in libtxt).
This also amends tools/const_finder/test/const_finder_test.dart to look
for a const an additional four lines down to account for the copyright
header added to the test fixture.
The dart SDK needs to ship several packages which have opted into null safety for the tech preview. This requires the use of a package_config.json for compilation as this file contains the language versions. Use a dart script to generate the package_config file from the .packages file, and include that in the DEPS hooks section.
Fixesflutter/flutter#60628
- Added a --experimental--emit-debug-metadata flag to Flutter frontend server
- False by default
- Passed to the frontend server in the SDK
- Introduced in change https://dart-review.googlesource.com/c/sdk/+/150181
This was only necessary when the Engine had to build in multiple buildroots
where the sources where checked out at different paths relative to the
buildroot. This is no longer the case and there are already cases GN rules
have been written that mix and match variable usage with the direct
specification of the path to the Flutter sources relative to the sole buildroot.
