WillPopScope widget can detect your backpress

@override
Widget build(BuildContext context) {
  return WillPopScope(
    onWillPop: () async {
      ///your code here...
      return false;
    },
    child:Scaffold(), 
  );
}

You need to navigate it to your desired page after acquired the BACK event.

onPressed: () => Navigator.push(
              context,
              MaterialPageRoute(builder: (context) => Data()),

Use WillPopScope method and return false. This method will detect BACK press. – Krina chauhan Jul 04 '22 at 10:45
