Can you please help me with a solution to a problem that I am facing using go_router package in my flutter application.

Sample code:

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

final _router = GoRouter(
  initialLocation: '/',
  routes: [
    GoRoute(
      path: '/',
      name: 'homepage',
      builder: (context, state) => const MyHomePage(),
      routes: [
        GoRoute(
          path: 'shoppingcart',
          name: 'cartpage',
          pageBuilder: (context, state) => MaterialPage(
            key: state.pageKey,
            fullscreenDialog: true,
            child: const ShoppingCartScreen(),
          ),
        )
      ],
    ),
  ],
);

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp.router(
      debugShowCheckedModeBanner: false,
      routerConfig: _router,
    );
  }
}

class MyHomePage extends StatelessWidget {
  const MyHomePage({
    super.key,
  });

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: const Text('App Bar'),
          actions: [
            IconButton(
              icon: const Icon(Icons.shopping_cart),
              onPressed: () => context.pushNamed('cartpage'),
            ),
          ],
        ),
        body: Container(
          color: Colors.green[200],
          child: const Center(child: Text("Home Page")),
        ));
  }
}

class ShoppingCartScreen extends StatelessWidget {
  const ShoppingCartScreen({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('shopping cart page'),
      ),
      body: Container(
        color: Colors.purple[200],
        child: const Center(child: Text("Shopping Cart Screen")),
      ),
    );
  }
}

Steps to point out issue:

-Step 1: Run below flutter app code on chrome browser. -Step 2: Click on Shopping Cart icon to go to another screen. -Step 3: click hot reload

by clicking hot reload go_router is not persisting "Shopping Cart Screen", instead it is showing home screen.

What is the solution if I want to stay on same screen after hot reload?

I am using go_router 5.2.0 in my flutter project but it is not supporting hot reload with the code mentioned above.

So far, Flutter have not support Hot Reload for Web. Whenever you press Ctrl + F or even the Hot Reload button, it performs Hot Restart instead.
