stream_mixin

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

Breaking change in 2.0.0

Migrated to null safety

Intention

The intention for this package is, instead of using state, we can use this package for streaming data from our controller/adapter/service to the widgets, which will result in better performance and cleaner code.

Getting Started

To subscribe a class instance, create the class with StreamMixin

Create a service class

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 ?? 'No tag selected yet.'),
      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.update(element: 'COVID-19');
}
