使用AnnotatedRegion是最适合我的，特别是如果我没有AppBar

import 'package:flutter/services.dart';

...

Widget build(BuildContext context) {
   return Scaffold(
      body: AnnotatedRegion<SystemUiOverlayStyle>(
         value: SystemUiOverlayStyle.light,                
         child: ...,
      ),
   );
}

你可以在Android上使用:

 import 'package:flutter/services.dart';

void main() {
  SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
    systemNavigationBarColor: Colors.blue, // navigation bar color
    statusBarColor: Colors.pink, // status bar color
  ));
}

这招对我很管用:

然后添加:

@override
  Widget build(BuildContext context) {

    SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
      statusBarColor: Colors.white,
      statusBarBrightness: Brightness.dark,
    ));
    return MaterialApp(home: Scaffold(

我认为这对你有帮助:

SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
        systemNavigationBarColor: Colors.white, // navigation bar color
        statusBarColor: Colors.white, // status bar color
        statusBarIconBrightness: Brightness.dark, // status bar icons' color
        systemNavigationBarIconBrightness: Brightness.dark, //navigation bar icons' color
    ));

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),
    );
  }
}

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) {}
}
