void main() {
  final emitter = Mitt();
  // listen to an event
  emitter.on(Symbol('foo'), eventHandler: (e) => print('foo $e'));

  // listen to all events
  emitter.on(Symbol('*'), wildcardHandler: (type, e) => print('$type $e'));

  // fire an event
  emitter.emit(Symbol('foo'), [
    <String, String>{'a': 'b'}
  ]);

  emitter.all.clear();

  // working with handler references:
