Flutter Navigation pop to index 1

Question

I am recursively adding routes to the navigator. There could be 20 views or more. Pop works as advertised, but I would like to pop to index 1 and remove all push history.

//========================================================
          new ListTile(
            title: new RaisedButton(
              child: new Text("POP until"),
              onPressed: () {
                var route = new MaterialPageRoute(
                  builder: (BuildContext context) =>
                      new NextPage3(value:"hi there from 3"),
                );
               //Navigator.pop(context, ModalRoute.withName('/'));
                Navigator.popUntil(context,ModalRoute.withName('/'));                
              },
            ),
          ),
//========================================================

replace .pop with .popUntil, actually works very elegantly.
