capybara_devtools_bloc

Shows a Flutter app's blocs and cubits in Capybara's State tab: one store per instance, a bloc's changes named after the event that made them.

Works with bloc 9, next to capybara_devtools, which connects the app to Capybara.

Use

void main() {
  Capybara.run(() {
    WidgetsFlutterBinding.ensureInitialized();
    Bloc.observer = CapybaraBlocObserver(parent: Bloc.observer);
    runApp(const MyApp());
  });
}

parent keeps the observer the app had: Capybara's passes every call on to it.

States show as their fields when they have toJson() (json_serializable, freezed) or Equatable's props, otherwise as their toString(); events show the same way under their type. A closed bloc shows as closed.

In release builds the observer only passes calls on to parent.
