scoped_listenable 1.4.0

Provides a Listenable to descendant widgets.

Getting started

Add scoped_listenable as a dependency in your pubspec.yaml file.

Usage

Provide a Listenable to descendant widgets.

ScopedListenable(
  listenable: counterModel,
  child: MyApp(),
);

Observe changes in the Listenable provided by an ancestor widget.

ScopedBuilder<CounterModel>(
  builder: (context, listenable, child) {
    return Text('${listenable.counter}');
  },
);

Advanced

To add multiple ScopedListenables, use ScopedContainer.

ScopedContainer(
  container: [
    ScopedListenable.from(counterModel),
    // Or
    counterModel.scoped(),
    // Or
    ScopedListenable.builder((context, child) {
      return ScopedListenable(
        listenable: counterModel,
        child: child,
      );
    }),
  ],
  child: MyApp(),
);

To obtain Listenable directly, use extension methods.

void initState() {
  context.get<CounterModel>().reset();

Widget build(BuildContext context) {
  final counterModel = context.watch<CounterModel>();
