I have added flutter in an existing Android app and I have been facing issues with File picker library not working.
After some debugging I believe it's due to GeneratedPluginRegistrant not being registered.
I Believe using a FlutterFragmentActivity is not mandatory with a FlutterFragment Please correct me if I am wrong, as mentioned in this doc document.
Now without FlutterFragmentActivity I can't override configureFlutterEngine method and can't register Plugins manually using below code.
GeneratedPluginRegistrant.registerWith(flutterEngine)
I have looked through everywhere but haven't found a way to register plugins without using FlutterFragmentActivity.
