Navigation Routes

I need to go to my home page on tap of a Middle screen button. For some reason I have already emptied the Navigation Stack.

I tried runApp(MyApp()); Its not working

    onTap: () {
      print('sdg');
      runApp(MyApp1());
      }

You can use Navigator

Navigator.push(context, MaterialPageRoute(builder: (context) => WidgetName()));

in your case use

onTap: () {
      print('sdg');
       Navigator.push(context,
        MaterialPageRoute(builder: (context) => MyApp1()));
      }
