AuthMiddleware in children of QRoute.withChild not work

[min23asdw]

on app_routes.dart

  final routes = <QRoute>[
    WebRoutes().route, // Add the dashboard routes
  ];

on web_router.dart

class WebRoutes {
  final route = QRoute.withChild(
      name: "web",
      path: '/',
      initRoute: '/homePage',
      builderChild: (router) => WebPage(router: router),
      middleware: [],
      children: [
        QRoute(
          path: '/homePage',
          builder: () => MyHomePage(),
        ),
        QRoute(
            path: '/CampaignDetail',
            builder: () => NotFoundView(),
            children: [
              QRoute(
              )
            ]),
        QRoute(
            path: '/profile',
            middleware: [
              AuthMiddleware(),
            ],
            builder: () => Profile()
        ),
        QRoute(
          path: '/login',
          builder: () => const LoginView(),
        ),
      ]);
}         

class AuthMiddleware extends QMiddleware {
  final authService = Get.find<AuthService>();

  @override
  Future<String?> redirectGuard(String path) async {

    if (authService.isAuth) {
      return null;
    }
    return '/login';
  }
}

if I click button in website that QR.to profile [ www.xxx.com/profile] if user not login it will redirect to /login [ www.xxx.com/login ] can work normally

but if I enter [www.xxx.com/profile ] in browser url bar that not Init Page
my web redirect to /login [ www.xxx.com/login ] but LoginView() not load and show

I found how to solve

when i remove QR.setUrlStrategy(); in main.dart

it work!!!! LoginView() is loaded

it mean setUrlStrategy have something wrong?

[min23asdw]

I found way to solve with still use setUrlStrategy becase in root stack tree if user enter web by www.xxx.com/profile , that are not root of route the middle will display key[0] web (root route ) on top of the stack

that mean web don't have anything to display it will display Init page -> loading problem

by add QR.navigator.switchTo('/login'); in middleware

class AuthMiddleware extends QMiddleware {
  final authService = Get.find<AuthService>();
  @override
  Future<String?> redirectGuard(String path) async {
    print('authService  run');
    if (authService.isAuth) {
      return null;
    }
    QR.navigator.switchTo('/login');
    return '/login';
  }
}

I not sure it a good way but it work

Using this example, I could not reproduce the problem

import 'package:flutter/material.dart';
import 'package:qlevar_router/qlevar_router.dart';

void main() {
  QR.setUrlStrategy();
  runApp(const MyApp());
}

var isAuth = false;

class AuthMiddleware extends QMiddleware {
  @override
  Future<String?> redirectGuard(String path) async {
    if (isAuth) {
      return null;
    }
    return '/login';
  }
}
