Differnt status bar color on differet pages in flutter

  @override
  Widget build(BuildContext context) {
    SystemChrome.setSystemUIOverlayStyle(
        const SystemUiOverlayStyle(statusBarColor: Colors.white));
    return MaterialApp(
      

I used this code to change the status bar color on one screen, when I nevigate to the next screen I have a different color on that using the same lines of code. But the problem is that when I navigate back to this page it doesn't change it back to white, it only changes when the page is loaded initally. Please guide me.
