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. is there a way to replace this pop command with something like... returntoIndex0...

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

Answer 1

If you do not use named routes, you can use

Navigator.of(context).popUntil((route) => route.isFirst);

Answer 2

In case you know exactly how many pops should be performed:

For example for 2 pops:

count = 0;
Navigator.popUntil(context, (route) {
    return count++ == 2;
});
