Flutter change app icon

1. Go to https://icon.kitchen and design your icon. Select Circle shape. Download and unzip. In the mipmap-xxxhdpi directory under android rename the largest file to icon.png. Then copy this file to the flutter app images directory.
   
   
2. Under dev_dependencies in pubspec.yaml, add the following:
   

     flutter_launcher_icons: ^0.13.1
   
   flutter_icons:
     android: 'launcher_icon'
     ios: true
     image_path: 'images/icon.png'

3. Run the following commands:
   

   flutter pub get
   flutter pub run flutter_launcher_icons:main

4. Run the app and verify that the new icon is displayed.
