2. MaterialApp component and Title property

MaterialApp is a very important component in Flutter. It encapsulates some necessary components for the application to implement Material Design, such as theme color, routing, localization, etc. Among them, the Title attribute is what we will focus on today.

The main function of the Title attribute is to provide a short description for the application, which is usually displayed in the task manager or application switcher. On Android devices, the value of the Title property is displayed in the recent task list; on iOS devices, the value of the Title property is displayed in the multitasking switcher. The value of this attribute plays an important role in improving the recognizability of the application.

Setting the Title property of MaterialApp is very simple, you only need to assign a value to the Title property when creating the MaterialApp component, as shown below:

MaterialApp(
  title: 'My Flutter App',
  // ...其他属性
)

3. Actual combat: use MaterialApp Title to manage application titles

In this chapter, we will use a practical example to introduce in detail how to use the Title property of MaterialApp in actual development.

First, we create a new Flutter project. In your terminal or command line, run the following command:

flutter create my_app

Then, open lib/main.dartthe file, find the MaterialApp component, and set the Title property to "My Flutter App", as shown below:

MaterialApp(
  title: 'My Flutter App',
  home: Scaffold(
    appBar: AppBar(
      title: Text('Home'),
    ),
    body: Center(
      child: Text('Hello World'),
    ),
  ),
)

Now, you can run your app and view the app's Title in the task manager or app switcher.

On Android devices, you can view a list of recent tasks by tapping the "Recent Tasks" button (usually a square button). In this list, you should see your application, and the Title you set.

On iOS devices, you can open the multitasking switcher by double-tapping the "Home" button or using gestures. In this interface, you should be able to see your application and the Title you set.

Four. Summary

This article details the Title property of MaterialApp, including what it does, how to set it, and how it behaves on different platforms. By reading this article, you should have understood the importance of the Title attribute and how to use it in your application.

Although the Title attribute is simple, it plays an important role in improving the recognizability of the application. In actual development, we should make full use of this property to provide a short and meaningful description for our application.
