Support using flutter-dev as the Flutter entrypoint script #5651
Description
flutter-dev is a version of flutter used by developers working on flutter_tools that runs the tool from source instead of precompiling the tool as a snapshot on first run and using the precompiled snapshot for subsequent runs.
Dart-Code should provide support for using flutter-dev to reduce some friction for flutter_tools developers.
From some local experimentation where I renamed flutter-dev to flutter and updated bin/internal/shared.sh to not try to build a snapshot for flutter instead of flutter-dev, it looks like Dart-Code does make use of the existence of bin/cache/flutter_tools.snapshot to determine if the tool is initialized:
