events method

@override Stream<DataEvent> events(String key, String creatorKey)

Setup a EventChannel to the native side for a window identified by key.

The creatorKey is used as a unique value for each instance of a window, to ensure the right engine is linking up to the right event channel. Should default to the current window's key.

Implementation

@override
Stream<DataEvent> events(
  String key,
  String creatorKey,
) =>
    throw UnimplementedError();
