dash 1.0.5 dash: ^1.0.5 copied to clipboard
Dash library is responsible to offer a service locator pattern that cares about provide and dispose blocs.
Dash #
Dash is a simple but efficient library that provides and dispose 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
anddash_generator
to your pubspec.yaml under the dev_dependencies section:
dev_dependencies:
build_runner: ^2.0.3
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 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();
}
@override
void dispose() {
$Provider.dispose<MyOtherBloc>();
super.dispose();
}
