Nested Navigation using GetNavigator

[nivisi]

Describe the bug Unable to use the GetNavigator for nested navigation.

Reproduction code

I've made a tiny repro project. It is placed in this repo.

The snippet of GetNavigator usage:

class HomePage extends GetView<HomeController> {
  final pages = [
    Navigator(
      key: Get.nestedKey(AppRoutes.todosKey),
      initialRoute: AppRoutes.todos,
      onGenerateRoute: (settings) {
        return GetPageRoute(
          settings: settings,
          page: () {
            if (settings.name == '/') {
              return Text('Initial');
            }
            if (settings.name == AppRoutes.todos) {
              return TodosPage();
            }
            final id = settings.name.replaceFirst(AppRoutes.todos + '/', '');
            Get.put(TodoController(id));

            return TodoPage();
          },
        );
      },
    ),
    GetNavigator(
      key: Get.nestedKey(AppRoutes.notesKey),
      initialRoute: AppRoutes.notes,
      getPages: [
        GetPage(
          name: AppRoutes.notes,
          page: () {
            return NotesPage();
          },
        ),
        GetPage(
          name: '${AppRoutes.notes}/:id',
          binding: NoteBinding(),
          page: () {
            return NotePage();
          },
        ),
      ],
    ),
  ];
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('GetNavigator Issue'),
        actions: [
          IconButton(
            onPressed: () {
              Get.toNamed('${AppRoutes.test}/ThisIsTheTest');
            },
            icon: Text('Test'),
          )
        ],
      ),
      bottomNavigationBar: GetBuilder(
        init: controller,
        builder: (controller) => BottomNavigationBar(
          currentIndex: controller.index,
          onTap: controller.changeIndex,
          items: [
            BottomNavigationBarItem(
              icon: Icon(Icons.today),
              label: 'Todos',
            ),
            BottomNavigationBarItem(
              icon: Icon(Icons.note),
              label: 'Notes',
            ),
          ],
        ),
      ),
      body: GetBuilder(
        init: controller,
        builder: (controller) => IndexedStack(
          children: pages,
          index: controller.index,
        ),
      ),
    );
  }
}

And this is the output I see in the console:

=[GETX] Route "/notes" not found

Expected behavior GetNavigator is available to use for nested navigation.

Flutter Version: 2.0.6

Getx Version: 4.1.4

Hey! Thanks for an awesome package.

Nested navigation is a required feature in my project. I've seen examples using the standard Flutter Navigator, and they work. But the GetNavigator is way more powerful than the default navigator. It would be nice to use it for named navigation.

May I know why unable to use GetRouterOutlet only after imported the Getx package? Pubspec already declare version 4.1.4 and other feature is working fine.

GetNavigator class on the latest release does not even support initialRoute property! why is that. and this navigator class is so weak and ofc not working anyway.

[derekpitts28]

Why is the initial route not supported. So weird!

[vegidio]

I found this issue 2 years after it was first created but it seems there's not a solution for it yet?

initialRoute is such a fundamental thing to make a navigator works and it's weird it's no longer present. Regardless, the lack of documentation in the lib makes everything much worse.

It is being solved in version ^5.0.0-release-candidate-4. You can use it.
