onChange method

@protected @mustCallSuper void onChange(Change<EditorBaseState<SimpleImageModel>> change)

Called whenever a change occurs with the given change. A change occurs when a new state is emitted. onChange is called before the state of the cubit is updated. onChange is a great spot to add logging/analytics for a specific cubit.

Note: super.onChange should always be called first.

@override
void onChange(Change change) {
  // Always call super.onChange with the current change
  super.onChange(change);

  // Custom onChange logic goes here
}

Implementation

@protected
@mustCallSuper
void onChange(Change<State> change) {
  // ignore: invalid_use_of_protected_member
  _blocObserver.onChange(this, change);
}
