Flutter used to generate a lib/generated_plugin_registrant.dart file on flutter pub get. This was changed to generate the registrant only when compiling/building.

This has become a problem for Dartpad, which relied on the generated_plugin_registrant.dart to be available without doing flutter build.

See relevant issue: dart-archive/dart-services#874

Restore the feature of generating a generated_plugin_registrant.dart file on flutter pub get that is usable by Dartpad (maybe a dartpad_plugin_registrant.dart file somewhere in side .dart_tool or similar?)
