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

Question

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.

At first go to ios/Runner folder. Next open info.plist and add the following lines into the Dict section.

<key>UIUserInterfaceStyle</key>
<string>Light</string>
<key>UIViewControllerBasedStatusBarAppearance</key>
<true/>

Next. Make sure you have these lines in Theme settings of your MaterialApp:

...
MaterialApp(
    themeMode: ThemeMode.light, // Change it as you want
    theme: ThemeData(
        primaryColor: Colors.white,
        primaryColorBrightness: Brightness.light,
        brightness: Brightness.light,
        primaryColorDark: Colors.black,
        canvasColor: Colors.white,
        // next line is important!
        appBarTheme: AppBarTheme(brightness: Brightness.light)),
    darkTheme: ThemeData(
        primaryColor: Colors.black,
        primaryColorBrightness: Brightness.dark,
        primaryColorLight: Colors.black,
        brightness: Brightness.dark,
        primaryColorDark: Colors.black,      
        indicatorColor: Colors.white,
        canvasColor: Colors.black,
        // next line is important!
        appBarTheme: AppBarTheme(brightness: Brightness.dark)),
...

Good luck!

P.S. You don't have to set brightness Here!! anymore :)

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

Under ios/Runner in Info.plist add

<key>UIUserInterfaceStyle</key>
<string>Light</string>
<key>UIViewControllerBasedStatusBarAppearance</key>
<true/>

it worked for me.

I found my question just the same as the flutter Issue#41067 ---"Flutter not automatically changing the status bar icons to black on devices running iOS 13.0 in Dark Mode it only does so when Dark Mode on iOS 13 is turned off #41067"

And the Issue state is Opening, so just hope it will be resolved as soon as possible. The issue link just below: flutter issue#41067
