解决方案

首先，您将设置 Flutter Launcher Icons

  1. 设置配置文件

     dev_dependencies:
 flutter_launcher_icons: "^0.7.3"

 flutter_icons:
 android: "launcher_icon"
 ios: true
 image_path: "assets/icon/icon.png"

如果您将配置文件命名为 flutter_launcher_icons.yaml 或 pubspec.yaml 以外的名称，则需要在运行包时指定文件名。

注意：如果您不使用现有的 pubspec.yaml，请确保您的配置文件位于与其相同的目录中。

  1. 运行包

      flutter pub get
  flutter pub run flutter_launcher_icons:main

使用这个插件
