Samsung Galaxy S10 System Navigation Bar Icon Brightness Issue #39132
Description
I'm testing on my Samsung Galaxy S10 device and the code works once and when I close and reopen the app, the navigation bar has all of its icons white. To get the navigation bar icons to go dark again, I have to hit the green refresh button in VS Code while in debug mode. Then, the navbar icons turn dark until I close the app and reopen it. However, if I force stop it, the icons turn dark which is what I want but I'm worried that when I build my app that if a user just leaves the app for a second and comes back, their navigation bar would be all messed up and they wouldn't be able to see the buttons. I just want to be able to know why this happens and find a way to fix it.
Expected Result:
Actual Result:
Code:
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
SystemChrome.setPreferredOrientations(
[DeviceOrientation.portraitDown, DeviceOrientation.portraitUp]);
SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.light.copyWith(
systemNavigationBarColor: Colors.white,
systemNavigationBarIconBrightness: Brightness.dark));
return MaterialApp(
debugShowCheckedModeBanner: false,
title: 'School Life',
home: HomeScreen(),
);
}
}
class HomeScreen extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
color: Colors.white,
),
appBar: AppBar(
iconTheme: IconThemeData(color: Colors.black),
backgroundColor: Colors.white,
brightness: Brightness.light,
elevation: 0,
centerTitle: true,
title: Text("Home",
style: TextStyle(
color: Colors.black,
fontFamily: 'OpenSans',
fontWeight: FontWeight.w600)),
),
drawer: CustomDrawer(),
);
}
}
Cmd: flutter doctor -v
