The Intention

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

Basic example

class CountService with StreamMixin<int> {
  increment() {
    update(lastUpdate ?? 0 + 1);
  }
}

/// You can either create a global instance of CountService or create a
/// singleton like class by adding the following in CountService class
/// ```dart
///   CountService._();
///   static CountService instance = CountService._();
/// ```
final countService = CountService();

anywhereInTheApp() {
  countService.increment();
}

Widget someWidget() {
  return StreamBuilder<int>(
    stream: countService.onChange,
    builder: (cxt, snap) => Text((snap.data ?? 0).toString()),
  );
}
