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
));

当您不使用AppBar时，更改状态栏的颜色

首先导入这个

import 'package:flutter/services.dart';

现在使用下面的代码改变状态栏的颜色在你的应用程序，当你不使用AppBar

SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.dark.copyWith(

    statusBarColor: AppColors.statusBarColor,/* set Status bar color in Android devices. */
    
    statusBarIconBrightness: Brightness.dark,/* set Status bar icons color in Android devices.*/
    
    statusBarBrightness: Brightness.dark)/* set Status bar icon color in iOS. */
); 

在iOS中使用安全区域时，更改状态栏的颜色

Scaffold(
  body: Container(
    color: Colors.red, /* Set your status bar color here */
    child: SafeArea(child: Container(
      /* Add your Widget here */
    )),
  ),
); 

使它像你的应用程序栏颜色

import 'package:flutter/material.dart';

 Widget build(BuildContext context) {
  SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
      statusBarColor: Colors.transparent,
      systemNavigationBarColor: Colors.transparent,
  ));
 }

这个也可以

SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.dark);
SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.light);

@override
Widget build(BuildContext context) {
  return Theme(
    data: ThemeData(brightness: Brightness.dark),
    child: Scaffold()
    ....
  )
}

[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());
}
