Flutter – How to check if dialog is shown when using go_router

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

    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.
