ValueNotifier

Tip

As of Signals 0.6.0 any Signal created with the flutter import implement ValueNotifier by default.

import 'package:signals/signals_flutter.dart';

final count = signal(0);
assert(count is Signal<int>);
assert(count is ValueNotifier<int>);

You can replace any ValueNotifier with a Signal and implement both APIs.

 import 'package:flutter/foundation.dart';
 import 'package:signals/signals_flutter.dart';
 final count = ValueNotifier(0);
 final count = signal(0);

count.addListener(() => print(count.value));
count.value = 1;
print(count.value);
count.notifyListeners();
count.dispose();

To create a mutable signal from a ValueNotifier, use the toSignal extension:

final notifier = ValueNotifier(10);
final signal = notifier.toSignal();

Setting the value on the signal or notifier will update the other.
