Add a Flutter View
Flutter can be added to an Android app as a single View in an Activity's View hierarchy.
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.
If you really need to add Flutter as a single View then do the following.
How to use FlutterView
Create and start a FlutterEngine
Create and start a FlutterEngine by following the appropriate instructions. See the FlutterEngine page
Create a FlutterView and add to layout
// Instantiate a new FlutterView.
FlutterView flutterView = new FlutterView(this);
// Add your FlutterView wherever you'd like. In this case we add
// the FlutterView to a FrameLayout.
FrameLayout frameLayout = findViewById(R.id.framelayout);
frameLayout.addView(flutterView);
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
flutterView.attachToFlutterEngine(flutterEngine);
At this point you should see your Flutter UI rendering to your FlutterView, and touch interaction should work.
Create and configure platform plugin
TODO(mattcarroll): update this info about the platform plugin
Fundamental communication between the Android platform and your Flutter app takes place over a MethodChannel with the name "flutter/platform". For example, Android's onPostResume() call must be forwarded over the flutterPlatformChannel with the message "AppLifecycleState.resumed".
platformPlugin = new PlatformPlugin(activity);
MethodChannel flutterPlatformChannel = new MethodChannel(
flutterEngine.getDartExecutor(),
"flutter/platform",
JSONMethodCodec.INSTANCE
);
flutterPlatformChannel.setMethodCallHandler(platformPlugin);
