@mit-mit mentioned this package would be a better fit for the dart team to own. Current plan:

1. Make Dart folks admin on https://github.com/google/platform.dart
2. Transfer https://github.com/google/platform.dart to the dart-lang org
3. Sync latest changes from https://github.com/flutter/packages/tree/main/packages/platform to https://github.com/dart-lang/platform.dart:
   Bring over latest files from flutter/packages dart-archive/platform#46
4. Update repo and issue links in the package to the new source location:
   Bring over latest files from flutter/packages dart-archive/platform#46
5. Publish updated package:
   Prepare for publishing dart-archive/platform#47
6. Update publisher in pub.dev to dart.dev
7. Remove source from https://github.com/flutter/packages:
   Remove package:platform source packages#6898
8. Remove platform from the issue template:
