Steps to reproduce

  1. Run the code sample
  2. Execute a hot reload

Expected results

I expected the hot reload to succeed.

Actual results

An exception occurred:

The following assertion was thrown while finalizing the widget tree:
Multiple widgets used the same GlobalKey.
The key [GlobalObjectKey int#c5097] was used by multiple widgets. The parents of those widgets were different widgets that both had the following description:
  Builder
A GlobalKey can only be specified on one widget at a time in the widget tree.

Code sample

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

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

class MainApp extends StatefulWidget {
  const MainApp({super.key});

  @override
  State<MainApp> createState() => _MainAppState();
}

class _MainAppState extends State<MainApp> {
  late final GlobalKey<NavigatorState> rootNavigatorKey;
  late final GlobalKey<NavigatorState> shellNavigatorKey;

  @override
  initState() {
    super.initState();
    rootNavigatorKey = GlobalKey<NavigatorState>();
    shellNavigatorKey = GlobalKey<NavigatorState>();
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp.router(
      routerConfig: GoRouter(
        navigatorKey: rootNavigatorKey,
        routes: [
          ShellRoute(
            navigatorKey: shellNavigatorKey,
            builder: (context, state, child) => child,

    I only see the error when all three of these conditions are met:

    1. The GoRouter has a GlobalKey
    2. The ShellRoute has a Global Key
    3. The ShellRoute uses the builder parameter

    If the GoRouter does not use a GlobalKey, the ShellRoute does not use a GlobalKey, or the ShellRoute uses the pageBuilder parameter, then the error is not thrown.

    The documentation shows ShellRoute being used in this configuration.

    Also, the related issues here and here use ShellRoute with a GlobalKey and the builder parameter.

    the related issues here and here use ShellRoute with a GlobalKey and the builder parameter.

    @swrenn Also #113409 should be the same / similar issue you are facing. For this issue, even though the error is triggered after hot reload, but the root-cause of all these issues seems to be same, as the log entries are same. I suggest you to follow-up in these issue for further updates, as fixing one of them should resolve other ones as well. If you agree, you can close this as duplicate.

    I narrowed the issue down further. The absence of the error when using the pageBuilder parameter implicates the subroutine _buildPlatformAdapterPage:

      Page<Object?> _buildPlatformAdapterPage(
    BuildContext context,
    GoRouterState state,
    Widget child,
  ) {
    // build the page based on app type
    _cacheAppType(context);
    return _pageBuilderForAppType!(
      key: state.pageKey,
      name: state.name ?? state.path,
      arguments: <String, String>{
        ...state.pathParameters,
        ...state.uri.queryParameters
      },
      restorationId: state.pageKey.value,
      child: child,
    );
  }

    The line that makes the difference is key: state.pageKey. I can reproduce the error using the pageBuilder parameter by using state.pageKey.

      pageBuilder: (context, state, child) {
    return NoTransitionPage(
      key: state.pageKey,
      child: child,
    );
  },

    @darshankawar, do you think there is merit in keeping this issue open? This issue

    • more closely mirrors the example in the documentation and the error others will discover when following it than the related issues. For example, the documentation does not mention CupertinoTabScaffold, CupertinoNavigationBar, or nested ShellRoutes.
    • may help others by highlighting the pageBuilder parameter as an alternative

    This issues is simply caused by the anti-pattern of creating (and recreating) the GoRouter inline inside the build method. Compare it for instance to how you wouldn't create objects like TabController, ScrollController or other non-Widget objects (like Listenables etc) in this manner.

    Ideally, there should be some kind of lint that would catch this problem though, or at the very least documentation warning about this. There is however an issue tracking this problem: #127206
