Part of https://github.com/flutter/flutter/issues/147883. Excluding Fuchsia and the Web SDK, the remaining scripts are: ```sh $ ./tools/find_pubspecs_to_workspacify.sh /Users/matanl/Developer/engine/src/flutter/impeller/tessellator/dart/pubspec.yaml /Users/matanl/Developer/engine/src/flutter/sky/packages/sky_engine/pubspec.yaml /Users/matanl/Developer/engine/src/flutter/shell/vmservice/pubspec.yaml /Users/matanl/Developer/engine/src/flutter/lib/snapshot/pubspec.yaml /Users/matanl/Developer/engine/src/flutter/lib/gpu/pubspec.yaml /Users/matanl/Developer/engine/src/flutter/lib/web_ui/pubspec.yaml /Users/matanl/Developer/engine/src/flutter/flutter_frontend_server/pubspec.yaml ``` These could be the trickiest, so I'm doing them separately.
