onTransition method
void
onTransition(
- Transition<
EditorBaseEvent< transitionDividerModel> , EditorBaseState<DividerModel> >
inherited
Called whenever a transition
occurs with the given 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.
A great spot to add logging/analytics at the individual Bloc
level.
Note: super.onTransition
should always be called first.
@override
void onTransition(Transition<Event, State> transition) {
// Always call super.onTransition with the current transition
super.onTransition(transition);
// Custom onTransition logic goes here
}
See also:
BlocObserver.onTransition
for observing transitions globally.
Implementation
@protected
@mustCallSuper
void onTransition(Transition<Event, State> transition) {
// ignore: invalid_use_of_protected_member
_blocObserver.onTransition(this, transition);
}
