flutter 应用名称由包名显示，AppBar标题显示在首页的AppBar ，那么标题MaterialApp(title: 'Rectangle App',);在哪里用在flutter项目中。

import 'package:flutter/material.dart';

void main() => runApp(new MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Rectangle App',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Rectangle App Home Page'),
        ),
        body: HelloRectangle(),
      ),
    );
  }
}

最佳答案

这是个好问题。下面是它的使用说明:

A one-line description used by the device to identify the app for the user.

On Android the titles appear above the task manager's app snapshots which are displayed when the user presses the "recent apps" button. Similarly, on iOS the titles appear in the App Switcher when the user double presses the home button.

简而言之:

• 在 Android 上:用于最近的应用程序

• iOS:应用切换器中使用

文档更新了(具体更新时间我不知道)

A one-line description used by the device to identify the app for the user. On Android the titles appear above the task manager's app snapshots which are displayed when the user presses the "recent apps" button. On iOS this value cannot be used. CFBundleDisplayName from the app's Info.plist is referred to instead whenever present, CFBundleName otherwise. To provide a localized title instead, use [onGenerateTitle].

所以这个值对iOS没有影响
