A simple custom stream builder library based on BLOC pattern. Uses stream underneath.

Features

This allows easy adding of data from network and disposing of bloc

How To Use Custom Bloc

class Example extends StatefulWidget {
  const Example({Key? key}) : super(key: key);

  @override
  State<Example> createState() => _ExampleState();
}

class _ExampleState extends State<Example> {
  final counterBloc = CounterBloc();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Column(
        children: [
          Expanded(
            child: CustomStreamBuilder<int, String>(
              stream: counterBloc.behaviorSubject,
              dataBuilder: (context, data) {
                return ListView.separated(
                  itemCount: 1,
                  scrollDirection: Axis.horizontal,
                  padding: const EdgeInsets.symmetric(horizontal: 4),
                  itemBuilder: (context, index) {
