Signal<T> class abstract interface

A writable interface for signals that allows modification.

This interface extends ReadonlySignal to provide write access to the signal's value.

Example:

Signal<int> counter = Signal(0);
counter.value++;

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.

readonly() → ReadonlySignal<T>: Available on Signal<T>, provided by the JoltSignalExtension extension
Returns a read-only view of this signal.
set(T value) → T: Sets a new value for this reactive value.
inherited
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.
update(T updater(T value)) → T: Available on WritableNode<T>, provided by the JoltWritableExtension extension
Updates the value using an updater function based on the current value.
