io.flutter.app.FlutterActivityDelegate.ViewFactory Interface Reference

Inheritance diagram for io.flutter.app.FlutterActivityDelegate.ViewFactory:

Public Member Functions
FlutterView	createFlutterView (Context context)
FlutterNativeView	createFlutterNativeView ()
boolean	retainFlutterNativeView ()

Detailed Description

Specifies the mechanism by which Flutter views are created during the operation of a
FlutterActivityDelegate.

A delegate's view factory will be consulted during onCreate(Bundle). If it returns null, then the delegate will fall back to instantiating a new full-screen
FlutterView.

A delegate's native view factory will be consulted during onCreate(Bundle). If it returns null, then the delegate will fall back to instantiating a new
FlutterNativeView. This is useful for applications to override to reuse the FlutterNativeView held e.g. by a pre-existing background service.
