onTransition method

@override void onTransition(Bloc bloc, Transition transition)

Called whenever a transition occurs in any bloc with the given bloc and transition. A transition occurs when a new event is added and a new state is emitted from a corresponding EventHandler. onTransition is called before a bloc's state has been updated.

Implementation

@override
void onTransition(Bloc bloc, Transition transition) {
  super.onTransition(bloc, transition);
  if (onTransitionFunc != null) {
    onTransitionFunc!(bloc, transition);
  }
  transitions.add(
    TransitionInfo(
      bloc: bloc.runtimeType.toString(),
      transition: transition,
      timestamp: DateTime.now(),
    ),
  );
}
