scoped_listenable 2.0.0

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 ScopedListenable.merge.

ScopedListenable.merge(
  listenables: [
    ScopedListenable.from(counterModel),
    // Or
    counterModel.scoped(),
  ],
  child: MyApp(),
);

To obtain Listenable directly, use extension methods.

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

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