Methods

addListener(Listener<E> listener, {bool fireImmediately = true}) → RemoveListener
Subscribes to this object.
inherited
clearDebounce() → void
inherited
debounce({required void action(), required String tag, Duration duration = const Duration(milliseconds: 300), bool immediate = true}) → void
Executes the action so that it will only be executed when there is no further repeated actions with same tag in a given frame of duration.
inherited
debugEntityUpdate(E update(E)) → E
A development-only way to update entity outside of UseCase.
dispose() → void
Frees all the resources associated with this object.
override
getDomainModel<M extends DomainModel>() → M
getInput<S extends SuccessDomainInput>(DomainModel domainModel) → Future<UseCaseInput<S>>
getInternalInput<S extends SuccessDomainInput>(DomainModel domainModel) → FutureOr<Either<FailureDomainInput, S>>
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
request<S extends SuccessDomainInput>(DomainModel domainModel, {required InputCallback<E, S> onSuccess, required InputCallback<E, FailureDomainInput> onFailure}) → Future<void>
setInput<I extends DomainInput>(I input) → void
subscribe<M extends DomainModel, I extends DomainInput>(RequestSubscription<M, I> subscription) → void
toString() → String
A string representation of this object.
inherited
transformToDomainModel<M extends DomainModel>(E entity) → M
updateShouldNotify(E old, E current) → bool
Whether to notify listeners or not when state changes
override
withSilencedUpdate(FutureOr<void> updater()) → Future<void>
The entity updates within the updater will not be notified to the UseCase listeners, but will silently update it.

Operators

operator ==(Object other) → bool
The equality operator.
