Before adding Flutter as a single View, you should consider if it is possible to add Flutter as a Fragment or an Activity to reduce your development burden.

FrameLayout frameLayout = findViewById(;

Your FlutterView will not render anything at this point because it is not backed by any particular Flutter app.

Attach your FlutterView to your FlutterEngine


At this point you should see your Flutter UI rendering to your FlutterView, and touch interaction should work.

  platformPlugin = new PlatformPlugin(activity);
  MethodChannel flutterPlatformChannel = new MethodChannel(
