return Scaffold(
      backgroundColor: STATUS_BAR_COLOR_HERE,
      body: SafeArea(
        child: scaffoldBody(),
      ),
);

如果你想改变整个应用程序的状态颜色，你可以像这样使用primaryColorDark属性:

void main() {
  runApp(
    MaterialApp(
      home: HomeWidget(),
      theme: ThemeData(
        primaryColorDark: Colors.white,
      ),
    ),
  );
}

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());
}

对于那些有iOS和Android颜色不一致的问题的人来说，这个方法对我来说很管用:

import 'dart:io';

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

return AppBar(
      systemOverlayStyle: (Platform.isIOS)
          ? SystemUiOverlayStyle.light
          : const SystemUiOverlayStyle(
            statusBarColor: pbsBlue,
            statusBarIconBrightness: Brightness.light,
            statusBarBrightness: Brightness.light,
          ),
      backgroundColor: Colors.blue,
      title: Text('Home'),
    );

请注意，这是AppBar可重用小部件的摘录。

最好的办法就是不用包装

Scaffold(
      extendBodyBehindAppBar: true,
      appBar: AppBar(
        toolbarHeight: 0,
        backgroundColor: Colors.transparent,
        elevation: 0,
        systemOverlayStyle: const SystemUiOverlayStyle(
          statusBarColor: Colors.transparent, // <-- SEE HERE
          statusBarIconBrightness:
              Brightness.dark, //<-- For Android SEE HERE (dark icons)
          statusBarBrightness: Brightness.light,
        ),
      ),.......

你可以这样做，

SystemChrome.setSystemUIOverlayStyle(
      SystemUiOverlayStyle(
        statusBarColor: Colors.grey.withOpacity(0.5),
        statusBarIconBrightness: Brightness.dark,
        statusBarBrightness:
            Platform.isAndroid ? Brightness.dark : Brightness.light,
        systemNavigationBarColor: Colors.white,
        systemNavigationBarDividerColor: Colors.grey,
        systemNavigationBarIconBrightness: Brightness.dark,
      ),
    );

将此代码添加到主程序中。省道构建方法，
