Flutter-How to change the Statusbar text color in Dark Mode?

I hope to control the statusbar text color in iOS 13 Dark Mode. I could change the statusbar color by setting the Scaffold's AppBar property "brightness" When not open the Dark Mode. Codes just like below:

return Scaffold(
      appBar: AppBar(
        brightness: Brightness.light,  //<--Here!!!
        title: Text(widget.title),
      ),
...

The effort just like this:

light brightness:

dark brightness:

But when I enable the simulator's Dark Mode, the method is not working. Open the simulator's "Dark Appearance":

After opening the "Dark Appearance", the statusbar text color couldn't change any more by the method, it's just in white color(lightness mode).

I have tried those method to change statusbar text color:

Method 1:

void main() {
  SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.light);
  SystemChrome.setPreferredOrientations([
    DeviceOrientation.portraitUp,
    DeviceOrientation.portraitDown
  ]);
  runApp(MyApp());
}

Method 2:

return AnnotatedRegion<SystemUiOverlayStyle>(
      value: SystemUiOverlayStyle.light,
      child: Material(
        child: Scaffold(
          appBar: AppBar(
            brightness: Brightness.light,
            title: Text(widget.title),
          ),
          body: Center(

But neither of them could work.

Hope your help! Thank you.
