CodePudding user response：

There can potential problem if this is a first screen and you use the pop method then you will get an error because you have nothing to pop.

Try to check the first possibility of navigation poping like in the example below

OutlinedButton(
    onPressed: () {
        //ClearSession();
        if (Navigator.canPop(context)) {
            Navigator.pop(context, true);
         }
         Navigator.pushReplacement(context, 
             MaterialPageRoute(builder: (context) => const Home()));
     },
     child: const Text("Submit"),
 ),
