In Add2App, when closing a FlutterView by calling finish() on the activity that hosts the view, a leak is present. The offender is a method channel that we have in a long living delegate that we've created which is given the DartExecutor from the engine that we've created and cached.

It seems that some the channel ends up having a reference to a TextInputPlugin instance which has a reference to the FlutterView which never gets released when the FlutterView is closed.

I'm attaching the screenshots of the leak.
