I was using Navigator 1 then I migrated to go_router to support deep links and web.
Sometimes when I send HTTP requests, I show a loading dialog using showDialog() until the response is processed, after processing I need to check if a dialog is shown or not, if shown I dismiss it using Navigator.of(context).pop().

When I was using Navigator 1, I used to do that in this way:
if (ModalRoute.of(context)?.isCurrent == false) Navigator.of(context).pop();
But now after migrating to go_router this doesn't work as I found that ModalRoute.of(context) always equals to null whether there is a dialog shown or not.

I tried using if (Navigator.of(context).canPop()) Navigator.of(context).pop();, but this doesn't differentiate between dialogs and screens, if there is no dialog shown it pops the current screen.

You can do this by checking the location of GoRouter

if (GoRouter.of(context).location == '/dialog'){  Check here
    context.pop();
}

Assuming your dialog route has path /dialog

  • Thanks for your help, But I actually don't show the dialog using the router, I use the `showDialog()` method which I believe uses the `Navigator` to push the dialog. I updated my question. So, I can't check for the location as I don't link the dialog to any route. – Khalid Muhammad Jan 11 '23 at 00:35

I just use context.pop() on dialog dismiss.

Previously did it this way, but tends to throw.

Set a Global variable:

GlobalKey<NavigatorState> navKey = GlobalKey<NavigatorState>();

In GoRouter specify:

navigatorKey: navKey

Pop dialog the 'old' way with:

Navigator.pop(navKey.currentContext!);

Correct me if it gives issues please.
