Member Function Documentation

provideFlutterEngine()

FlutterEngine dev.flutter.scenarios.SpawnMultiEngineActivity.provideFlutterEngine ( @NonNull Context  context )

inline

Hook for subclasses to easily provide a custom io.flutter.embedding.engine.FlutterEngine.

This hook is where a cached io.flutter.embedding.engine.FlutterEngine should be provided, if a cached FlutterEngine is desired.

Reimplemented from io.flutter.embedding.android.FlutterActivity.

Definition at line 17 of file SpawnMultiEngineActivity.java.

                                                                      {
    FlutterEngineGroup engineGroup = new FlutterEngineGroup(context);
    FlutterEngineGroup.Options options =
        new FlutterEngineGroup.Options(context).setAutomaticallyRegisterPlugins(false);
    FlutterEngine firstEngine = engineGroup.createAndRunEngine(options);
 
    FlutterEngine secondEngine = engineGroup.createAndRunEngine(options);
 
    // Check that a new engine can be spawned from the group even if the group's
    // original engine has been destroyed.
    firstEngine.destroy();
    FlutterEngine thirdEngine = engineGroup.createAndRunEngine(options);
 
    return thirdEngine;
  }
