`ReadonlySignal<T> toSignal({String? debugLabel, bool autoDispose = false})`

ReadonlySignal from ValueListenable#

Converted ValueListenable objects become readable signals that automatically listen to the underlying source. When the source updates, the signal updates.

The signal automatically manages the subscription, disposing of the listener when the signal itself is disposed.

Example: Converting a ValueNotifier#

final ValueListenable<int> listenable = ValueNotifier(10);
final signal = listenable.toSignal();

print(signal.value); // 10

Example: ValueListenable from ReadonlySignal#

To convert back to a standard ValueListenable for native Flutter compatibility:

final signal = Signal(10);
final listenable = signal.toValueListenable();
