onEvent method Null safety

  1. @protected
  2. @mustCallSuper
void onEvent(
  1. Event 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
}

Implementation

@protected
@mustCallSuper
void onEvent(Event event) {
  // ignore: invalid_use_of_protected_member
  observer.onEvent(this, event);
}
