A custom hook to retrieve a generic signal from a SignalProvider ancestor higher up in the widget tree.
Under the hood, this uses the BuildContext to look up the provider and registers a reactive dependency.
Supports standard core signals from package:signals_core/signals_core.dart as well
as Flutter-native signals.
Example Usage#
class CounterDisplayWidget extends HookWidget {
const CounterDisplayWidget({super.key});
@override
Widget build(BuildContext context) {
final counter = useSignalProvider<Signal<int>>();
if (counter == null) return const Text('Not found');
return Text('Value: ${counter.value}');
}
}
