dash 0.5.1

Dash library is responsible to offer a BlocProvider pattern that cares about dispose all the streams of blocs.

Dash

Dash is a simple but efficient library that provides BloCs class without headaches.

IMPORTANT: Dart2 is required to use this package.

Installation

• Add dash to your pubspec.yaml under the dependencies section:

dependencies:
  dash: ^latest_version

• Add build_runner and dash_generator to your pubspec.yaml under the dev_dependencies section:

dev_dependencies:
  build_runner: ^1.1.3
  dash_generator: ^latest_version

Usage

1 - Create a provider class that is going to gathering all BlocProvider annotation:

IMPORTANT: Do not forget to add: part 'provider.g.dart';.

import 'package:dash/dash.dart';

part 'provider.g.dart';

@BlocProvider.register(MySampleBloc)
@BlocProvider.register(MyOtherBloc)
abstract class Provider {}

2 - Extends all your bloc class from Bloc. It will allow you to override disposable and dispose method.

IMPORTANT: All bloc class must has an instance() function that returns the instance of the bloc class as bellow.

class MySampleBloc extends Bloc {

  @override
  dispose() {
    //close all streams
  }

  static Bloc instance() => MySampleBloc();
  
}

class MyOtherBloc extends Bloc {

  @override
  dispose() {
    //close all streams
  }

  static Bloc instance() => MyOtherBloc();
}

3 - Run build_runner, it will generate the provider.g.dart class that you added as part on your provider class.

On project directory run on terminal:

pub run build_runner build

For flutter is:

flutter packages pub run build_runner build

Note: If you encounter a conflict error, please add the --delete-conflicting-outputs argument to your command:

flutter packages pub run build_runner build --delete-conflicting-outputs

4 - Finally you can get your bloc class instance from wherever you want, example:

@override
  Widget build(BuildContext context) {
    final _bloc = $Provider.of<MyOtherBloc>();

    return Container();
  }
