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<dynamic, dynamic> bloc,
  Transition<dynamic, dynamic> transition,
) {
  super.onTransition(bloc, transition);
  final transitionString = transition.toString();
  final isFilterContains = filters.any(transitionString.contains);
  if (!settings.enabled || !settings.printTransitions || isFilterContains) {
    return;
  }
  final accepted = settings.transitionFilter?.call(bloc, transition) ?? true;
  if (!accepted) {
    return;
  }
  onBlocTransition?.call(bloc, transition);
  _iSpectify.logCustom(
    BlocStateLog(
      bloc: bloc,
      transition: transition,
      settings: settings,
    ),
  );
}
