flatter getx：在登录中间件中发生循环

我在我的示例项目中使用Getx，如下所示：

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return GetMaterialApp(
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      initialRoute: AppLinks.LOGIN,
      getPages: AppRoutes.pages,
      initialBinding: MainBinding(),
    );
  }
}

我有这样的路线：

class AppRoutes {
  static final pages = [
    GetPage(
      name: AppLinks.LOGIN,
      page: () => Login(),
      binding: LoginBinding(),
    ),
    GetPage(
      name: AppLinks.DASHBOARD,
      page: () => Dashboard(),
      middlewares: [
        AuthGuard(),
      ],
      children: [...

正如你所看到的，我宣布了一个Middelware：

  middlewares: [
    AuthGuard(),
  ],

这是一个简单的中间件：

class AuthGuard extends GetMiddleware {
  final authService = Get.find();

  @override
  int? get priority => 1;

  @override
  RouteSettings? redirect(String? route) {
    if (authService.isAuthenticated)
      return RouteSettings(name: AppLinks.LOGIN);
    else
      return RouteSettings(name: AppLinks.DASHBOARD);
  }
}

在登录页面中，我有一个按钮：

ElevatedButton(
  style: ElevatedButton.styleFrom(
    primary: Colors.red,
    onPrimary: Colors.green,
    onSurface: Colors.pink,
  ),
  onPressed: () => controller.toDashboard(),
  child: Text("Dashboard"),
)

在它的控制器里我有这个：

class LoginController extends GetxController {
  toDashboard() => Get.toNamed(AppLinks.DASHBOARD);
}

但当我打电话时toDashboard方法I在该语句中进入循环：

  @override
  RouteSettings? redirect(String? route) {
    if (authService.isAuthenticated)
      return RouteSettings(name: AppLinks.LOGIN);
    else
      return RouteSettings(name: AppLinks.DASHBOARD);
  }
}

我正在使用：

environment:
  sdk: ">=2.12.0 <3.0.0"
dependencies:
  flutter:
    sdk: flutter
  cupertino_icons: ^1.0.2
  get: ^4.3.4
