io.flutter.embedding.android.FlutterEngineProvider Interface Reference

Inheritance diagram for io.flutter.embedding.android.FlutterEngineProvider:

Public Member Functions
FlutterEngine	provideFlutterEngine (@NonNull Context context)

Detailed Description

Provides a io.flutter.embedding.engine.FlutterEngine instance to be used by a
FlutterActivity or FlutterFragment.

io.flutter.embedding.engine.FlutterEngine instances require significant time to warm up. Therefore, a developer might choose to hold onto an existing io.flutter.embedding.engine.FlutterEngine and connect it to various FlutterActivitys and/or FlutterFragments. This interface facilitates providing a cached, pre-warmed io.flutter.embedding.engine.FlutterEngine.

Member Function Documentation

provideFlutterEngine()

FlutterEngine io.flutter.embedding.android.FlutterEngineProvider.provideFlutterEngine

(

@NonNull Context

context

)

Returns the io.flutter.embedding.engine.FlutterEngine that should be used by a child FlutterFragment.

This method may return a new io.flutter.embedding.engine.FlutterEngine, an existing, cached FlutterEngine, or null to express that the FlutterEngineProvider would like the FlutterFragment to provide its own FlutterEngine instance.

Parameters

context

The current context. e.g. An activity.

Returns

The Flutter engine.

Implemented in io.flutter.embedding.android.FlutterActivity, io.flutter.embedding.android.FlutterActivityAndFragmentDelegate.Host, io.flutter.embedding.android.FlutterFragment, io.flutter.embedding.android.FlutterFragmentActivity, io.flutter.embedding.android.FlutterActivityTest.FlutterActivityWithProvidedEngine, and io.flutter.embedding.android.FlutterFragmentActivityTest.FlutterFragmentActivityWithProvidedEngine.
