我已经尝试了很多方法和修复，但我的应用程序图标仍然没有显示。我正在使用颤振，我使用了这个flutter_launcher_icons包，但仍然没有用。
这是我的 pubspec.yaml dev_depend：
dev_dependencies:
flutter_launcher_icons: "^0.7.3"
flutter_test:
sdk: flutter
这里是配置：
flutter_icons:
android: "launcher_icon"
ios: "AppIcon"
image_path_ios: "assets/icon/icon.png"
image_path: "assets/icon/icon.png"
这是我的 AppIcon 文件
这是我的flutter doctor：
