    just wrap the Scaffold with WillPopScope

    WillPopScope(
  onWillPop: () async {
    SystemNavigator.pop();
    return false;
  },
  child:...
}

    Wrap your Page’s Scaffhold with WillPopScope Widget and add this invokeMethod to onWillPop.

    return WillPopScope(
      onWillPop: () async {
        await SystemChannels.platform.invokeMethod('SystemNavigator.pop');
        return false;
      },
      child: Scaffold(...),
   );
