onTransition method

void onTransition(
  1. Bloc bloc,
  2. 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 mapEventToState executed. onTransition is called before a bloc's state has been updated. A great spot to add universal logging/analytics.


void onTransition(Bloc bloc, Transition transition) => null;
