AsyncNotifier<T> class

A ChangeNotifier that holds a current state of asynchronous computation.

When set, setFuture or setStream is called, the AsyncNotifier will notify its listeners with the latest AsyncSnapshot of it.

Properties

hashCode → int
The hash code for this object.
no setterinherited
hasListeners → bool
Whether any listeners are currently registered.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
snapshot → AsyncSnapshot<T>
The current state of the AsyncNotifier.

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
set(FutureOr<T> futureOrValue, {T initialData()?, (Object, StackTrace?) initialError()?, bool resetSnapshot = false}) → void
Track a FutureOr and notify listeners with the latest AsyncSnapshot of it. If futureOrValue is not a Future, the snapshot will be transitioned to ConnectionState.done with the provided value synchronously.
setFuture(Future<T> future, {T initialData()?, (Object, StackTrace?) initialError()?, bool resetSnapshot = false}) → void
Track a Future and notify listeners with the latest AsyncSnapshot of it.
setStream(Stream<T> stream, {T initialData()?, (Object, StackTrace?) initialError()?, bool resetSnapshot = false}) → void
Track a Stream and notify listeners with the latest AsyncSnapshot of it.
toString() → String
A string representation of this object.

Operators

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