Detailed Description

This class is owned by the io.flutter.embedding.engine.FlutterEngine and its role is to managed its connections with Android App Components and Flutter plugins.

It enforces the {0|1}:1 relationship between activity and engine, and propagates the app component connection to the plugins.
