inherited
get() → T

Available on Readable<T>, provided by the JoltUtilsReadableExtension extension

Gets the current value.
listen(void onData(T event)?, {Function? onError, void onDone()?, bool? cancelOnError, bool immediately = false}) → StreamSubscription<T>

Available on Readable<T>, provided by the JoltUtilsStreamExtension extension

Listens to changes in this reactive value.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notify() → void
Manually notifies all subscribers that this signal has changed.
override
onDispose() → void
Called when the node is being disposed.
inherited
toString() → String
A string representation of this object.
override
until(bool predicate(T value)) → Future<T>

Available on ReadableNode<T>, provided by the JoltUtilsUntilExtension extension

Waits until the value satisfies a condition.
untilWhen<U>(U predicate) → Future<T>

Available on ReadableNode<T>, provided by the JoltUtilsUntilExtension extension

Waits until the reactive value equals a specific value.

Operators

operator ==(Object other) → bool
