DelegatedSignal<T> class

A writable signal that shares a source with reference counting.

When disposed, decrements the reference count. The source is automatically disposed when all delegated signals are disposed.

Parameters:

• delegated: The reference-counted helper managing the source

Example:

final helper = DelegatedRefCountHelper<Signal<int>>(source);
final delegated = DelegatedSignal(helper);
delegated.value = 10; // Updates shared source

Implemented types

• Signal<T>

Available extensions

• JoltSignalExtension
• JoltUtilsReadableExtension
• JoltUtilsStreamExtension
• JoltUtilsUntilExtension
• JoltUtilsWritableExtension

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

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.

update(T updater(T value)) → T

Available on Writable<T>, provided by the JoltUtilsWritableExtension extension
