flutter_bloc_debug #

A set of helper tools for debugging your BLoCs.

Bloc debug views #

If you start by designing your BLoCs, it can be tedious to test them in real condition (if you have native dependencies and so on), and sometimes you don't have time to create a full set of unit tests for them during your prototyping phase.

With BlocDebugger and BlocDebugDrawer, a form is generated to allow you to display all of the Streams values, and to send values to Sinks.


Quickstart #

class CounterBloc {
  Sink<int> get add => ...
  Sink<void> get reset => ...
  Stream<int> get count => ...
Widget build(BuildContext context) {
     return BlocDebugger(
      title: 'Counter',
      streams: {'count': this.bloc.count},
      sinks: {'add': this.bloc.add, 'reset': this.bloc.reset},
      child: Scaffold(
          body: Counter(this.bloc), // The view you're working on
          endDrawer: BlocDebugDrawer()),

Generated bloc debugger declaration #

If you use my other package built_bloc, all the metadata of a bloc is generated and you simply have to call BlocDebugger.fromMetadata(bloc.metadata, ...).
