我如何访问main中的变量。到扑面而前的其他页面，我正在使用getx状态管理

Question

我如何访问main中的变量。以getx状态管理的扑面而来的其他页面，我想在Main中进行localmemberid。使用安全存储存储数据

main.dart

void main() {
  SecureStorage secureStorage = SecureStorage();
  var localMemberid; // i would like to make this varial global or pass this value to other pages

  runApp(
    ScreenUtilInit(
      builder: (BuildContext context, Widget? child) {
        return GetMaterialApp(
          title: "onyx",
          initialRoute: AppPages.INITIAL,
          getPages: AppPages.routes,
          theme: ThemeData(primarySwatch: MaterialColor(0xFF0456E5, color)),
        );
      },
    ),
  );

  SecureStorage.readLocalSecureData('memberid')
      .then((value) => localMemberid = value);
}

登录控制器

class LoginController extends GetxController {
  final AuthenticationRepo _authRepe = AuthenticationRepo();
  final SecureStorage secureStorage = SecureStorage();
  String? localMemberid; // i would like to get the localMemberid from the main.dart

  //TODO: Implement LoginController

  @override
  void onInit() {
    super.onInit();
  }

  @override
  void onReady() {
    super.onReady();
  }

  @override
  void onClose() {}

  var userid;
  var password;
  
 

  onSinginButton() async {
    var res = await _authRepe.login(username: userid, password: password);
    if (res.status == ApiResponseStatus.completed) {
      print(res.data);
      await SecureStorage.writeLocalSecureData('memberid', res.data!.memberid);
      localMemberid == null
          ? Get.toNamed(Routes.LOGIN)
          : Get.toNamed(Routes.HOME);
    } else {
      Get.defaultDialog(title: res.message.toString());
    }
  }
}

从主函数上升起变量，然后使其成为RX：

  var localMemberid=Rxn<String>(); // i would like to make this varial global or pass this value to other pages

void main() {
     SecureStorage secureStorage = SecureStorage();

     .......

   SecureStorage.readLocalSecureData('memberid')
      .then((value) => localMemberid.value = value);
   }

然后在loginController上删除字符串？ localmemberid; //和导入main.dart：

localMemberid.value == null
      ? Get.toNamed(Routes.LOGIN)
      : Get.toNamed(Routes.HOME);
