flutter - GetX Get.arguments 总是返回 null

Question

我有路由问题。我正在使用 GetX 并且 Get.arguments 总是返回 null。我在 route_generator.dart 中定义我的路线

class RouteGenerator {
  static Route<dynamic> generateRoute(RouteSettings settings) {
    switch (settings.name) {
      case AppRoutes.splashScreen:
        return GetPageRoute(
          page: () => const SplashPage(),
          binding: SplashBinding(),
          transition: Transition.fade,
        );
      case AppRoutes.unauthenticated:
        return GetPageRoute(
          page: () => const UnauthenticatedPage(),
          binding: UnauthenticatedBinding(),
          transition: Transition.fade,
        );
      case AppRoutes.login:
        return GetPageRoute(
          page: () => const LoginPage(),
          binding: LoginBinding(),
          transition: Transition.fade,
        );
      case AppRoutes.register:
        return GetPageRoute(
          page: () => const RegisterPage(),
          binding: RegisterBinding(),
          transition: Transition.fade,
        );
      case AppRoutes.dashboard:
        return GetPageRoute(
          page: () => DashboardPage(0),
          binding: DashboardBinding(),
          transition: Transition.fade,
        );
      case AppRoutes.editProfile:
        return GetPageRoute(
          page: () => const EditProfilePage(),
          binding: EditProfileBinding(),
          transition: Transition.rightToLeft,
        );
      default:
        return GetPageRoute(
          page: () => const SplashPage(),
          binding: SplashBinding(),
          transition: Transition.fade,
        );
    }
  }
}

这是我的 main.dart，我在其中指定路线

  @override
  Widget build(BuildContext context) {
    return GetMaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Test App',
      defaultTransition: Transition.rightToLeft,
      themeMode: ThemeMode.system,
      darkTheme: Themes.darkTheme,
      theme: Themes.lightTheme,
      initialRoute: AppRoutes.splashScreen,
      onGenerateRoute: RouteGenerator.generateRoute,
    );
  }

然后当我尝试使用它正常工作的路由启动新屏幕时，我无法检索参数，因为它们为空

list_view.dart

onTap: () => {
              Get.toNamed(AppRoutes.exerciseDetail, arguments: [
                {'exercise': exercise}
              ])
            },

打印返回空detail_view_controller.dart

  @override
  void onInit() {
    dynamic arguments = Get.arguments;
    print(arguments);
    super.onInit();
  }

感谢任何帮助或建议，谢谢:)

尝试使用 out [ ] 传递参数。比如这些参数:{'exercise': exercise}

你也可以这样尝试:

arguments:{'exercise': exercise, 'name':max}

并且可以访问它们:

Print(Get.arguments['name']);
// output max
