Add the following dependency to your project's pubspec.yaml.
notifier: <latest_version>
There are two methods that make the core of Notifier.
  • notify(action, data) - Sending data for a certain action.
  • register(action, callback) - Listening to data changes for a certain action.
Steps
  • Add NotifierProvider at root of project's Widget tree.
void main() {
  runApp(
    NotifierProvider(
      child: MyApp(),
    ),
  );
}
  • Register a callback for a certain action in your Widget tree.
@override
  Widget build(BuildContext context) {
    return Column(
      children: <Widget>[
        Text('Data from Notifier:'),
        Notifier.of(context).register<String>('action', (data) {
          return Text('${data.data}');
        }),
      ],
    );
  }
  • From anywhere in your application, call the notify method.
@override
  Widget build(BuildContext context) {
    Notifier _notifier = NotifierProvider.of(context);

    return Scaffold(
      body: Center(
        RaisedButton(
          child: Text('Notify'),
          onPressed: () {
            _notifier.notify('action', 'Sending data from notfier!');
          },
        ),
      ),
    );
  }

Things to be aware of!

  • If a callback is registered on an action with a specific data type T, then passing data with data type other than T in notify method will throw error.
