Flutter WillPopScope doesn't respond-CodePudding

I am trying to get back button of phone to go to specific page using WillPopScope but it does not work (won't respond) at all.

Code

@override
  Widget build(BuildContext context) {
    final args = ModalRoute.of(context)!.settings.arguments as ArticleArgument;

    return WillPopScope(
      onWillPop: () async {
        Navigator.pushReplacementNamed(
          context,
          '/category',
          arguments: CategoryArgument(
            args.catSlug,
            args.catName,
          ),
        );
        return true;
      },
      child: Scaffold(...)
     );
}

Any idea?

Try this:

  onWillPop: () async {
        await Navigator.pushReplacementNamed(
          context,
          '/category',
          arguments: CategoryArgument(
            args.catSlug,
            args.catName,
          ),
        );
        return true;
      }

with this line you can go back:

Navigator.pop(context);
