Flutter – Auto_route always opens the same first (page)

After pressing the "Kayıt Ol" button on the "Giriş Yap (Login)" page, I should go to the "Kayıt Ol (Signup)" page, but it adds the Login page to the stack and I can’t see the Signup page. Am I missing something? I can’t go another page from "Giriş Yap (Login)" page. I showed the case at below gif. I’m waiting your helping.

app_router.dart

part 'app_router.gr.dart';

@AutoRouterConfig(replaceInRouteName: AppRouter._replaceInRouteName)
final class AppRouter extends _$AppRouter {
  static const _replaceInRouteName = 'View,Route';
  @override
  List<AutoRoute> get routes => [
        AutoRoute(
          page: LoginRoute.page,
          initial: true,
          children: [
            AutoRoute(page: SignUpRoute.page),
          ],
        ),
      ];
}
