FlutterEngineProvider

All Known Implementing Classes:

FlutterActivity, FlutterFragment, FlutterFragmentActivity
```
public interface FlutterEngineProvider
```
Provides a FlutterEngine instance to be used by a FlutterActivity or FlutterFragment.
FlutterEngine instances require significant time to warm up. Therefore, a developer might choose to hold onto an existing FlutterEngine and connect it to various FlutterActivitys and/or FlutterFragments. This interface facilitates providing a cached, pre-warmed FlutterEngine.
