A simple mixin for adding a stream behaviour to any class object

Getting Started

To make a class subscribable create the class with [StreamMixin]

Create a service

class AppTagService with StreamMixin<String> {
  AppTagService._();
  static final AppTagService instance = AppTagService._();
}

Subscribe to change of the tag service

class CurrentTag extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return StreamBuilder<String>(
      builder: (context, snap) => Text(snap.data),
      stream: AppTagService.instance.onChange, //⭐
    );
  }
}

Change current tag

Note, tag can be changed from any place in the app because it does not need context or state.

someFunction() {
  AppTagService.instance.change('COVID-19');
}
