IOS app icon is not showing using flutter

Question

So I'm facing problem to set IOS app icon in simulator as well as physical device. I have created my own custom app icon for flutter application. also I have used flutter third party library flutter_launcher_icons: ^0.13.1 in dev_dependencies in pubspec.yaml file to generate and set app icon in both android and ios. I have also added below path into dev_dependencies:

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"

after that I have execute flutter pub run flutter_launcher_icons command to generate icons and that gives me following output:

Deprecated. Use `dart run` instead.
Building package executable... (7.0s)
Built flutter_launcher_icons:main.
This command is deprecated and replaced with "flutter pub run flutter_launcher_icons"
