在 main.dart 中调用 Bloc.observer 时遇到问题

Question

当我在 main.dart 中调用 Bloc.observer 时，它不起作用

Answer 1

你可以运行它通过防区

Runs body in its own error zone.

Creates a new zone using Zone.fork based on zoneSpecification and zoneValues, then runs body in that zone and returns the result.

 await runZonedGuarded(
    () async {
      await BlocOverrides.runZoned(
        () async => runApp(MyApp()),
        blocObserver: AppBlocObserver(),
      );
    },
    (error, stackTrace) => log(error.toString(), stackTrace: stackTrace),
  );
