I have used WillPopScope

WillPopScope(
            onWillPop: () => willPopScopeWid(),
            child:Container(
//SomeCode
)),

willPopScopeWid() {
    setState(() {
      onTapOfVideo = false;
    });
    return Navigator.pop(context);
  }

=>

Is there any other way to get rid of deprecated Widget?
