在我的应用程序中完全正常

import 'package:flutter_statusbarcolor/flutter_statusbarcolor.dart';

void main() => runApp(new MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    FlutterStatusbarcolor.setStatusBarColor(Colors.white);
    return MaterialApp(
      title: app_title,
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: HomePage(title: home_title),
    );
  }
}

当你在屏幕上有一个应用程序栏时，下面的答案就不再适用了。现在需要配置AppBarTheme。亮度和AppBarTheme。在这种情况下，systemOverlayStyle正确。

回答

而不是经常建议SystemChrome.setSystemUIOverlayStyle()，这是一个系统范围的服务，不会在不同的路由上重置，你可以使用AnnotatedRegion<SystemUiOverlayStyle>，这是一个小部件，只对你包装的小部件有效。

AnnotatedRegion<SystemUiOverlayStyle>(
   value: SystemUiOverlayStyle(
      statusBarColor: Colors.white,
  ),
  child: Scaffold(
      ...
  ),
)

适用于iOS和Android

import 'package:flutter/services.dart';

@override
Widget build(BuildContext context) {
  SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.dark);

  return Scaffold();
}
    

最新的解决方案。Flutter 2.0及以上

对于使用AppBar的用户:

/// WORKS on the screen where appBar is used
Scaffold(
      appBar: AppBar(
        systemOverlayStyle: SystemUiOverlayStyle(
          // statusBarColor: Colors.red, // You can use this as well
          statusBarIconBrightness: Brightness.dark, // OR Vice Versa for ThemeMode.dark
          statusBarBrightness: Brightness.light, // OR Vice Versa for ThemeMode.dark
        ),
      ),
     ), 

对于那些不使用AppBar的人:

将下面的代码放在根屏幕的构建功能上，以影响下面的所有屏幕:

void main() {
  runApp(MyApp());
}

// This widget is the root of your application.
class MyApp extends StatelessWidget {

  /// WORKS on every screen EXCEPT the screen in which appBar is used
  SystemChrome.setSystemUIOverlayStyle(
    SystemUiOverlayStyle(
      // statusBarColor: Colors.red, // You can use this as well
      statusBarIconBrightness: Brightness.dark, // OR Vice Versa for ThemeMode.dark
      statusBarBrightness: Brightness.light, // OR Vice Versa for ThemeMode.dark
    ),
  );
  @override
  Widget build(BuildContext context) {}
}

将下面的代码放在单个屏幕的构建功能上，只影响该屏幕:

class SingleScreen extends StatelessWidget {

  /// WORKS on a single screen where appBar is NOT used
  SystemChrome.setSystemUIOverlayStyle(
    SystemUiOverlayStyle(
      // statusBarColor: Colors.red, // You can use this as well
      statusBarIconBrightness: Brightness.dark, // OR Vice Versa for ThemeMode.dark
      statusBarBrightness: Brightness.light, // OR Vice Versa for ThemeMode.dark
    ),
  );
  @override
  Widget build(BuildContext context) {}
}

对于那些使用AppBar的人

如果你使用AppBar，那么更新状态栏颜色就像这样简单:

Scaffold(
  appBar: AppBar(
    // Use [Brightness.light] for black status bar 
    // or [Brightness.dark] for white status bar
    // https://stackoverflow.com/a/58132007/1321917
    brightness: Brightness.light 
  ),
  body: ...
)

申请所有应用程序栏:

return MaterialApp(
  theme: Theme.of(context).copyWith(
    appBarTheme: Theme.of(context)
        .appBarTheme
        .copyWith(brightness: Brightness.light),
  ...
  ),

对于那些不使用AppBar的人

用AnnotatedRegion包装您的内容，并将值设置为SystemUiOverlayStyle。light或SystemUiOverlayStyle.dark:

return AnnotatedRegion<SystemUiOverlayStyle>(
  // Use [SystemUiOverlayStyle.light] for white status bar 
  // or [SystemUiOverlayStyle.dark] for black status bar
  // https://stackoverflow.com/a/58132007/1321917
  value: SystemUiOverlayStyle.light,
  child: Scaffold(...),
);

以下是你需要知道的一切:

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

void main() {
  SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
    systemNavigationBarColor: Colors.amber, // navigation bar color
    statusBarColor: Colors.white, // status bar color
    statusBarIconBrightness: Brightness.dark, // status bar icon color
    systemNavigationBarIconBrightness: Brightness.dark, // color of navigation controls
  ));
  runApp(MyApp());
}
