当我使用flutter create命令创建应用程序时，flutter标志将用作两个平台的应用程序图标。
如果我想改变应用程序的图标，我是否应该去两个平台的目录并替换那里的图像?我说的平台目录是myapp/ios/Runner/Assets.xcassets/AppIcon。apppiconset用于iOS, myapp/android/app/src/main/res用于android。
或者可以将图像定义为颤振资产和图标以某种方式生成?

遵循以下步骤:-
1. 在pubspec中添加flutter_luncher_icons的依赖项。yaml文件。你可以在这里找到这个插件。
2. 在资产文件夹和pubspec中添加所需的图像。Yaml文件如下。
pubspec.yaml
name: NewsApi.org
description: A new Flutter application.
# The following line prevents the package from being accidentally published to
# pub.dev using `pub publish`. This is preferred for private packages.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev

3.执行terminal flutter pub get命令，然后执行flutter_luncher_icon命令。这是成功运行命令后得到的结果。并成功生成了午餐图标。

上面许多答案中推荐的flutter_launcher_icons包现在已经有一段时间没有更新了，并且正在抛出一个未捕获的异常。
你也可以使用icons_launcher包。
更新pubspec.yaml
dev_dependencies:
icons_launcher: ^1.1.7
flutter_icons:
image_path: 'assets/ic_logo_border.png'
ios: true
android: true
运行包
flutter pub get
flutter pub run icons_launcher:main
试试IconKitchen吧，它是Android Asset Studio的继承者，是为Android、iOS和网页制作高度自定义应用图标的绝佳新方法。
您必须将Flutter图标文件替换为您自己的图像。这个网站将帮助你把你的png转换成各种大小的启动器图标:
