状态栏中图标的颜色（Flutter）

Question

I was working with FLUTTER and the Design refers to black color for the status bar and the icon's color of the status bar must be white so how can I change statusbar icon's color in flutter?

Answer 1

Add the Snippet below to your main.dart . setSystemUIOverlayStyle allows one to change System overlay styles if any. This will do the job globally in your app.

SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
statusBarColor: Colors.transparent,
statusBarIconBrightness: Brightness.dark));

This will give you the effect below(iOS & Android). Play around with the properties in SystemUiOverlayStyle to get what you want.

Answer 2

To change the icon to white try the following inside the build method:

import 'package:flutter_statusbarcolor/flutter_statusbarcolor.dart';

class MyApp extends StatelessWidget {
 @override
  Widget build(BuildContext context) {
    FlutterStatusbarcolor.setStatusBarColor(Colors.white);
    FlutterStatusbarcolor.setStatusBarWhiteForeground(true);
...
}

The method setStatusBarWhiteForeground will change the color of the text and icon to white if it is set to true otherwise the color will be black.

Add this snippet in lib/main.dart file.

        class App extends StatelessWidget {
          // This widget is the root of your application.
          @override
          Widget build(BuildContext context) {
        
            // This code changes background color and icon color of status bar
            SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
              // statusBarColor is used to set Status bar color in Android devices.
              statusBarColor: Colors.transparent,
        
              // To make Status bar icons color white in Android devices.
              statusBarIconBrightness: Brightness.light,
        
              // statusBarBrightness is used to set Status bar icon color in iOS.
              statusBarBrightness: Brightness.dark,
              // Here light means dark icon color for Status bar.
            ));
        
            // material app widget
            return MaterialApp(
        
              // Status bar color
              theme: ThemeData(
                appBarTheme: AppBarTheme(
                  // Brightness.dark will show white color icon
                  brightness: Brightness.dark,
                ),
              ),
        
              color: Colors.white,
        
              title: 'App',
        
              home: Scaffold(),
            );
          }
        }

Update:

Use AppBar.systemOverlayStyle :

AppBar(
  systemOverlayStyle: SystemUiOverlayStyle(
    statusBarBrightness: Brightness.dark, // For iOS: (light icons)
    statusBarIconBrightness: Brightness.dark, // For Android: (dark icons)
    statusBarColor: ...,
  ),
)

Answer 5

From Flutter 2.4 onwards, you have to set the style directly, so:

AppBar(
  systemOverlayStyle: SystemUiOverlayStyle.dark,
)

This code works for Android and iOS.

Answer 6

I know I am late but for those who face the same issue

Add the following code to main.dart in the MaterialApp() theme property

MaterialApp(
       theme: ThemeData(
        appBarTheme: AppBarTheme(
                systemOverlayStyle: const SystemUiOverlayStyle(
                  statusBarColor: Colors.transparent,
                  statusBarBrightness: Brightness.dark, // For iOS: (dark icons)
                  statusBarIconBrightness: Brightness.dark, // For Android(M and greater): (dark icons)
                ))),
);

Noting that Brightness.dark provide dark icons and that's suitable for white background in black background case of course Brightness.light

Set to [Brightness.light], the system bar icons are white.

Set to [Brightness.dark], the system bar icons are black.

That will work globally in your app

If you want it for a specific page, there's a property in AppBar() called systemOverlayStyle: copy the same code above to it

AppBar(
    systemOverlayStyle: const SystemUiOverlayStyle(
                      statusBarColor: Colors.transparent,
                      statusBarBrightness: Brightness.dark, // For iOS: (dark icons)
                      statusBarIconBrightness: Brightness.dark, // For Android(M and greater): (dark icons)
                    ),
),
