Flutter项目iOS端应用图标无法显示问题求助

问题详情 #

Flutter项目中iOS应用图标在模拟器及真机上均无法显示。已制作自定义应用图标，在pubspec.yaml的dev_dependencies中引入flutter_launcher_icons: ^0.13.1，配置内容如下：

flutter_launcher_icons:
  android: "launcher_icon"
  ios: true
  remove_alpha_ios: true
  image_path: "assets/images/Launcher_Icon.png"
  min_sdk_android: 19 # android min sdk min:16, default 21
  web:
    generate: true
    image_path: "assets/images/Launcher_Icon.png"
    background_color: "#FFFFFF"
#    theme_color: "#hexcode"
  windows:
    generate: true
    image_path: "assets/images/Launcher_Icon.png"
    icon_size: 48 # min:48, max:256, default: 48
  macos:
    generate: true
    image_path: "assets/images/Launcher_Icon.png"

执行命令 flutter pub run flutter_launcher_icons 后，输出提示图标生成成功，但iOS端图标依旧无法正常显示。
