onEvent method

@override void onEvent(E event)

Called whenever an event is added to the Bloc. A great spot to add logging/analytics at the individual Bloc level.

Note: super.onEvent should always be called first.

@override
void onEvent(Event event) {
  // Always call super.onEvent with the current event
  super.onEvent(event);

  // Custom onEvent logic goes here
}

• BlocObserver.onEvent for observing events globally.

Implementation

@override
void onEvent(E event) {
  if (_lastEvent != null) {
    _lastPreviousEvent = _lastEvent;
  }

  super.onEvent(event);
}
