onChange method
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
}

BlocObserver
for observingCubit
behavior globally.
Implementation
@override
void onChange(Change<EditorState> change) {
_sendChangedEvent(change.nextState);
super.onChange(change);
}
