Methods

call() → T
Returns the current signal value (equivalent to value).
override
dispose() → void
Disposes this node and cleans up resources.
inherited
get() → T
Returns the current value and establishes a reactive dependency.
override
internalSet(T value) → T
Sets a new value for the signal and notifies subscribers when it changes.
listen(void onData(T event)?, {Function? onError, void onDone()?, bool? cancelOnError, bool immediately = false}) → StreamSubscription<T>

Available on ReadonlyNode<T>, provided by the JoltReadonlyExtension extension

Creates a stream subscription that 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
Disposes the signal and cleans up resources.
override
toString() → String
A string representation of this object.
inherited
until(bool predicate(T value)) → Future<T>

Available on ReadonlyNode<T>, provided by the JoltReadonlyExtension extension

Waits until the reactive value satisfies a predicate condition.

Operators

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