Work towards removal of package:archive and ideally more stable unzipping of artifacts. These commands are available in Powershell 5+, which we already require for windows.
Also combines experiments into extraGenSnapshot/ExtraFrontEndOptions. Allows providing --no-sound-null-safety to allow out of order migration and running.
Remove copying from the shutdown stage since that seems risky. If the tool copies the first compilation there will still be a decent dill for initialization.
If a dependency specified uses-material-design: true and the main pubspec specifies uses-material-design: false, then the MaterialIcons font would be included in the font manifest, but not in the AssetManifest or final bundle. Remove it from the FontManifest if this occurs
Work towards #16723
This is only safe to land after #58131 lands in google3. Only build NOTICES in asset manfiest, and load either LICENSE or NOTICES from pubspec dependencies.
PR #57749 included changes to the way the project interacts with the
build process (e.g., bundling the necessary library), so should have
incremented the template version to trigger the messaging to developers.
BundleUtilities apparently doesn't do build-system-style timestamp
analysis when deciding what to copy, and instead just doesn't copy
things that are already present. This cleans that bundle directory on
each build, so that it includes the up-to-date library versions.
Since this is just copying from build artifacts, this is very fast; the
build steps themselves are not affected.
Fixes https://github.com/flutter/flutter/issues/58049
Update the flutter and dart scripts' locking mechanism and follow_links function to be more robust and support more platforms.
This adds support for using mkdir as a fallback if the system doesn't have flock instead of using shlock, since shlock doesn't work on shared filesystems.
It also fixes a problem in the follow_links function where it failed when the link resolved to the root directory.
In #55864 a race condition was described where a done event is received before we finish connecting. This cannot happen, since async functions begin synchronously and the flag isWaitingForVm is tripped immediately, keeping onDone from exiting.
The CMake plugin build wasn't setting visibility to hidden by default,
which meant that plugins exported everything by default. This would make
bad interactions between plugins much more likely; only the intended API
should be exported by the shared library.
