Interface FlutterActivityDelegate.ViewFactory

All Known Implementing Classes:

FlutterActivity, FlutterFragmentActivity

Enclosing class:

FlutterActivityDelegate

public static interface FlutterActivityDelegate.ViewFactory

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

A delegate's view factory will be consulted during FlutterActivityDelegate.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 FlutterActivityDelegate.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.
