Flutter/Dart - Navigator.pop(context) - How to Pop two Contexts back?

Question

I've got;

screen/widget Home() which calls;
screen/widget MainStage() which calls;
future method futureStage() which builds;
PageViewBuilder StageBuilder() which contains;

SwipeGestureRecognizer which calls;

Navigator.push (context,
                  PageTransition(
                    type: PageTransitionType.downToUp,
                    child: HomeReply(),
                  ));

HomeReply() contains;
appBar with an arrow/button that allows the user to;
Navigator.pop(context);

How do I get the Navigator to pop back to Home()?

The navigator is a stack so you can use the popUntil method to pop back to your home() screen.

Navigator.popUntil(context, ModalRoute.withName('/home'));

or

Navigator.of(context).popUntil((route) => route.settings.name == "Home");

Sorry, I didn't saw your comment while writing my answer. Will delete it. – Zeeshan Hussain Aug 03 '20 at 11:36
I'm guessing that didn't work because I didn't use a named route in the first place. I've been using a BottomNavigationBar in Home() and it seemed easier to just call Navigator.push (context, PageTransition( type: PageTransitionType.downToUp, child: HomeReply(), )); – Meggy Aug 03 '20 at 12:29
So is there a way I can call Home() with popUntil? – Meggy Aug 03 '20 at 12:33
You can use route.settings.name. I personally did not try it without named parameters but I guess you can dehug a bit to see what routename is saved when you push home () and then use that? – Zeeshan Hussain Aug 03 '20 at 12:35

I used this code to check my Home() route. var route = ModalRoute.of(context); if(route!=null){ print(route.settings.name); } It gave me "/". So then I tried this; Navigator.of(context).popUntil((route) => route.settings.name == "/"); But unfortunately it didn't work. – Meggy Aug 03 '20 at 20:45

Turns out HomeReply() had an extra MaterialApp in the build. Once I removed this it all worked as normal with Navigator.pop(context);.
