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
    ));

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
    ));

大多数答案都是使用只适用于安卓系统的SystemChrome。我的解决方案是将AnnotatedRegion和SafeArea合并到新的小部件中，这样它也可以在iOS中工作。我可以在没有AppBar的情况下使用它。

class ColoredStatusBar extends StatelessWidget {
  const ColoredStatusBar({
    Key key,
    this.color,
    this.child,
    this.brightness = Brightness.dark,
  }) : super(key: key);

  final Color color;
  final Widget child;
  final Brightness brightness;

  @override
  Widget build(BuildContext context) {
    final defaultColor = Colors.blue;
    final androidIconBrightness =
        brightness == Brightness.dark ? Brightness.light : Brightness.dark;
    return AnnotatedRegion<SystemUiOverlayStyle>(
      value: SystemUiOverlayStyle(
        statusBarColor: color ?? defaultColor,
        statusBarIconBrightness: androidIconBrightness,
        statusBarBrightness: brightness,
      ),
      child: Container(
        color: color ?? defaultColor,
        child: SafeArea(
          bottom: false,
          child: Container(
            child: child,
          ),
        ),
      ),
    );
  }
}

用法:把它放在页面小部件的顶部。

@override
Widget build(BuildContext context) {
  return ColoredStatusBar(
    child: /* your child here */,
  );
}

我通过改变整个背景颜色来解决这个问题，如下所示:

在主界面:

return Scaffold(
      backgroundColor: Colors.black,
      body: SafeArea(
     ),
);

这(在脚手架内部)创建了一个带有浅色内容的黑色状态栏。(没有Appbar)

appBar: AppBar(
      toolbarHeight: 0,
      backgroundColor: Colors.black,
      systemOverlayStyle: SystemUiOverlayStyle.light,
    ),

[Android测试] 这就是为什么我能够使状态栏透明，文本颜色深，

import 'package:flutter/services.dart';

void main() {
  SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
    statusBarColor: Colors.transparent, // transparent status bar
    statusBarIconBrightness: Brightness.dark // dark text for status bar
  ));
  runApp(MyApp());
}
