WillPopScope deprecation warning

Question

i'm not a Flutter expert :( How can i convert this my widget to avoid WillPopScope?

@override
Widget build(BuildContext context) {
  return WillPopScope(
    onWillPop: () async {
      if (!Navigator.of(context).canPop()) {
        Navigator.of(context).pushReplacementNamed(Routes.welcome);
      } else {
        Navigator.of(context).pop();
      }
      return false;
    },
    child: Scaffold(
      resizeToAvoidBottomInset: false,
      primary: true,
      appBar: _buildAppBar(),
      body: BaseWidget(child: _buildBody()),
    ),
  );
}

I've found one similar question here but i can't do changes myself :(
