dispose method Null safety

  1. @override
  2. @mustCallSuper
Future<int> dispose()
@mustCallSuper, override

Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener and removeListener will throw after the object is disposed).

This method should only be called by the object's owner.

Implementation

@override
@mustCallSuper
Future<int> dispose() async {
  super.dispose();
  return 0;
}
