i already tried to delete all caches, plugin definitely not building with flutter 3.29

[master-wayne7]

We just have to remove the Registar import from the FacebookAppEventsPlugin.kt file, then it will work as expected.

You can use my fork until they merged... it was blocking us too thats why I forked and fixed it

[qeepcologne]

that's what we're already doing. But then you lose feature from other branch.
I do not want another fork.
please do not forget to merge feature/debug branch.

Flutter does not support this syntax anymore

      flutterEngine.getPlugins().add(new id.oddbit.flutter.facebook_app_events.FacebookAppEventsPlugin());
