    After flutter version 3.12.0 pre WillPopScope is deprecated.

    Now you can use PopScope as below

     return PopScope(
canPop:true,//When false, blocks the current route from being popped.
onPopInvoked: (didPop) {
            //do your logic here
            setStatusBarColor(statusBarColorPrimary,statusBarIconBrightness: Brightness.light);
           // do your logic ends
           return;
        },
          child: 
         // your other ui or logic
         Scaffold(//other child and ui etc)
)

    Any ideas how it use with this logic?

    WillPopScope(
  onWillPop: () => _onWillPop(context, model),
  child: anyChildWidget,
),

Future<bool> _onWillPop(
  BuildContext context,
  MyViewModel model,
) async {
    if (model.oneFieldIsFlled) {
      await MyUiKit.showCupertinoDialog(
        context: context,
        title: "Any title",
        barrierDismissible: false,
        description: "Any description",
        actions: [
          CustomCupertinoDialogAction(
            text: "Cancel",
            isDefaultAction: true,
            onPressed: () {
              model.shouldClose = false;
              Navigator.pop(context);
            },
          ),
          CustomCupertinoDialogAction(
            text: "Close",
            onPressed: () {
              model.shouldClose = true;
              Navigator.pop(context);
            },
          ),
        ],
      );
      return Future.value(model.shouldClose);
    } else {
      return Future.value(true);
    }
  }
