WhenFutureNotifier<T> class

A ChangeNotifier that provides snapshot of a future. The future can be recreated/refreshed by calling update. that uses futureBuilder to execute a future asynchronous computation.

Mixed in types

Constructors

WhenFutureNotifier(AsyncResultBuilderCallback<Future<T>> futureBuilder)

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).
inherited
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
setFutureValue(WhenFuture<T> whenFuture, FutureSnapshotListenerCallback<T>? listener, VoidCallback? onFinally) → Future<void>
Sets a value after an asynchronous computation that returned a future
inherited
toString() → String
A string representation of this object.
inherited
update({FutureSnapshotListenerCallback<T>? listener, VoidCallback? onFinally}) → void
Refreshes/Redoes a future asynchronous computation.

Operators

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