Methods

exists(ProviderBase<Object?> provider) → bool

invalidate(ProviderOrFamily provider) → void
Invalidates the state of the provider, causing it to refresh.
inherited
invalidateSelf() → void
Invalidates the state of the provider, causing it to refresh.
inherited
keepAlive() → KeepAliveLink
Requests for the state of a provider to not be disposed when all the listeners of the provider are removed.
listen<T>(ProviderListenable<T> provider, void listener(T? previous, T next), {bool fireImmediately, void onError(Object error, StackTrace stackTrace)?}) → ProviderSubscription<T>
Listen to a provider and call listener whenever its value changes.
override
listenSelf(void listener(State? previous, State next), {void onError(Object error, StackTrace stackTrace)?}) → void
Listens to changes on the value exposed by this provider.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Notify dependents that this provider has changed.
inherited
onAddListener(void cb()) → void
A life-cycle for whenever a new listener is added to the provider.
inherited
onCancel(void cb()) → void
Add a listener to perform an operation when the last listener of the provider is removed.
inherited
onDispose(void cb()) → void
Adds a listener to perform an operation right before the provider is destroyed.
inherited
onRemoveListener(void cb()) → void
A life-cycle for whenever a listener is removed from the provider.
inherited
onResume(void cb()) → void
A life-cycle for when a provider is listened again after it was paused (and onCancel was triggered).
inherited
read<T>(ProviderListenable<T> provider) → T
Read the state associated with a provider, without listening to that provider.
inherited
refresh<T>(Refreshable<T> provider) → T
Forces a provider to re-evaluate its state immediately, and return the created value.
inherited
toString() → String
A string representation of this object.
inherited
watch<T>(ProviderListenable<T> provider) → T
