class HomePage extends StatefulWidget {

class _HomePageState extends State<HomePage> {
  int _pageIndex = 0;

  @override

    return Scaffold(
      body: SafeArea(
        child: IndexedStack(
          index: _pageIndex,
          children: const <Widget>[
            NavigatorPage(child: Text('Home')),
            NavigatorPage(child: Text('Business')),
            NavigatorPage(child: Text('School')),
          ],
        ),
      ),
      bottomNavigationBar: BottomNavigationBar(
        items: const <BottomNavigationBarItem>[
          BottomNavigationBarItem(icon: Icon(Icons.home), title: Text('Home')),
          BottomNavigationBarItem(icon: Icon(Icons.business), title: Text('Business')),
          BottomNavigationBarItem(icon: Icon(Icons.school), title: Text('School')),
        ],
        currentIndex: _pageIndex,
        onTap: (int index) {
          setState(() { _pageIndex = index; });
        },
      ),
    );
  }
}

void main() {
  runApp(MaterialApp(home: HomePage()));
}

Actually my question is this; I have seen the gist and what I seek to achieve is popping the stack once I click on the bottom navigation Item once I'm deep in the navigation stack. Say I move two levels deeper on the home bottom Item, once I click on the home Icon , I should return to the home screen.

Hi ! Thanks for this ! Is there a way to control one navigator from somwhere else ? For example, when clicking the home button, the inner home navigator goes to the 1st page ?

Hello,
Thanks for the code.
With this solution I can't pass arguments over the road with pushNamed, you have a solution ?
