Methods
-
add(
Event event) → void - Adds an event to a queue.
-
bindState<
N> (N convert(State currentState)) → Stream< N> -
Maps current state stream to the new one using
convertmethod. Usesdistinctoperator to skip recurring values. -
buildGraph(
) → StateGraph< Event, State> - Method for building StateGraph instance.
-
close(
) → void - Closes bloc.
-
launchFuture<
T> (Future< T> action, {void onData(T event)?, Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<T> -
Launch
actionsubscription that will be closed on Bloc's close method call. Convertsactionto Stream and returns Future which is exactly launchStream subscription. -
launchStream<
T> (Stream< T> action, {void onData(T event)?, Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<T> -
Launch
actionsubscription that will be cancelled on Bloc's close method call. Returns immediately cancelled StreamSubscription if bloc was already disposed. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
onTransition(
State previousState, Event event, State newState) → void - Method called on each state transition.
-
reset(
State state) → void -
Resets state machine to given
state. -
singleLiveEventSubject<
T> () → SingleLiveEventSubject< T> - Builds subject for SingleLiveEvents. Is auto-closed on close method.
-
toString(
) → String -
A string representation of this object.
inherited
-
transformEvents(
Stream< Event> events) → Stream<Event> - Transforms events.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
