Flutter设置App的应用名字和应用logo图标的方法（android ios web）

在Flutter中设置应用的名称和图标，你需要在项目根目录下的pubspec.yaml文件中配置。以下是针对Android、iOS、Web的配置示例：

name: MyApp
description: A new Flutter application.
 
# App name displayed on the home screen.
# This value is only used on Android.
application_name: MyApp
 
# Icons and Launcher Icons
# The following icons are used when building for iOS, Android, and Web.
# You can specify custom icons for each platform by adding icons for
# iOS and Android in the respective folders (ios/Runner/Assets.xcassets/AppIcon.appiconset
# and android/app/src/main/res/).
flutter:
  # App name and icon for mobile devices.
  app:
    # Mobile app name.
    name: MyApp
    
    # Mobile app icon.
    # Place your icon in one of the following paths:
    # - ios/Runner/Assets.xcassets/AppIcon.appiconset (for iOS).
    # - android/app/src/main/res/mipmap-... (for Android).
    # - web/ (for Web).
    icon: assets/icons/my_app_icon.png
 
  # Web-specific configuration.
  web:
    # Web app's name as shown in the browser's tab.
    title: My App
    
    # Web app's favicon (shown in the browser's address bar).
    # Place your icon in the web/ directory.
    favicon: assets/icons/my_app_icon.png

对于iOS，你需要在Xcode中的Assets.xcassets进行设置。对于Android，则需要将图标图像放入对应的mipmap资源文件夹中。对于Web，你需要将图标放置在web目录下，并在web配置部分指定favicon。

请确保图标文件的分辨率和格式符合各自平台的要求。此外，在实际操作时，请根据你的项目实际需求，将assets/icons/my_app_icon.png替换为你的实际图标文件路径。
