Type NavigatorState not found

[AlexStroia]

Hi, I'm getting the following error:

lib/presentation/routes/app_router.gr.dart:14:26: Error: Type 'NavigatorState' not found.
  _$AppRouter([GlobalKey<NavigatorState>? navigatorKey]) : super(navigatorKey);
                         ^^^^^^^^^^^^^^
lib/presentation/routes/app_router.gr.dart:14:16: Error: Type 'GlobalKey' not found.
  _$AppRouter([GlobalKey<NavigatorState>? navigatorKey]) : super(navigatorKey);
               ^^^^^^^^^
lib/presentation/routes/app_router.gr.dart:14:16: Error: Expected 0 type arguments.
  _$AppRouter([GlobalKey<NavigatorState>? navigatorKey]) : super(navigatorKey);
               ^
lib/presentation/routes/app_router.gr.dart:14:26: Error: 'NavigatorState' isn't a type.
  _$AppRouter([GlobalKey<NavigatorState>? navigatorKey]) : super(navigatorKey);
                         ^^^^^^^^^^^^^^

  _$AppRouter([GlobalKey<NavigatorState>? navigatorKey]) : super(navigatorKey);
               ^^^^^^^^^

My AppRouter code is:
import 'package:auto_route/annotations.dart';
import 'package:auto_route/auto_route.dart';
import 'package:fithub/presentation/pages/forgot_password/forgot_password_page.dart';
import 'package:fithub/presentation/pages/register/register_page.dart';
import 'package:fithub/presentation/pages/sign_in/sign_in_page.dart';
part 'app_router.gr.dart';

const registerPath = "/register";
const forgotPasswordPath = "/forgot-password";
const signupPath = "/singup";

@MaterialAutoRouter(
  
  replaceInRouteName: 'Page,Route', routes: <AutoRoute>[
  AutoRoute(page: SignInPage, path: signupPath),
  AutoRoute(page: RegisterPage, path: registerPath, initial: true),
  AutoRoute(page: ForgotPasswordPage, path: forgotPasswordPath)
])

class AppRouter extends _$AppRouter{}        

My MaterialApp.router code is:

class FithubApp extends StatelessWidget {
  final _appRouter = AppRouter();

  FithubApp({Key? key}) : super(key: key);

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp.router(
      debugShowCheckedModeBanner: false,
      routerDelegate: _appRouter.delegate(),
      routeInformationProvider: _appRouter.routeInfoProvider(),
      routeInformationParser: _appRouter.defaultRouteParser(),
      title: 'Fithub',
      theme: appTheme(),
    );
  }
}

Spend the last two days trying to figure out what is happening. I'm running flutter 2.5.1

Hi, try add this import in your AppRouter file
import 'package:flutter/material.dart';

Could you please update the documentation with this? Because I feel like that's a pretty important thing for people to know, and not have to second-guess it, and/or browse GitHub issues from almost half a year ago.
