这招对我很管用:

进口服务

导入的包:颤振/ services.dart ';

然后添加:

@override
  Widget build(BuildContext context) {

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

对我有用的方法(适用于那些不用AppBar的人)

添加AppbBar首选颜色，然后设置:toolbarHeight: 0

 child: Scaffold(
    appBar: AppBar(
      toolbarHeight: 0,
      backgroundColor: Colors.blue,
      brightness: Brightness.light,
    )

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),
    );
  }
}

乌利希期刊指南: 推荐解决方案(Flutter 2.0及以上)

SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
  statusBarColor: Colors.white
));

    SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(

在Flutter 2.8:

AppBar(
    backgroundColor: YOUR_COLOR_HERE,
    toolbarHeight: 0,
);

更新Flutter 2.0(推荐):

在最新的Flutter版本上，您应该使用:

AppBar(
  systemOverlayStyle: SystemUiOverlayStyle(
    // Status bar color
    statusBarColor: Colors.red, 

    // Status bar brightness (optional)
    statusBarIconBrightness: Brightness.dark, // For Android (dark icons)
    statusBarBrightness: Brightness.light, // For iOS (dark icons)
  ),
)

只有Android(更灵活):

import 'package:flutter/services.dart';

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

iOS和Android:

appBar: AppBar(
  backgroundColor: Colors.red, // Status bar color
)

这有点老套，但适用于iOS和Android:

Container(
  color: Colors.red, // Status bar color
  child: SafeArea(
    left: false,
    right: false,
    bottom: false,
    child: Scaffold(
      appBar: AppBar(
        backgroundColor: Colors.blue, // App bar color
      ),
    ),
  ),
)
