Hello, thank you very much for your project. I would like to make a small contribution. I noticed that the app was using the default flutter icon, so I decided to fix that.

I used the flutter_launcher_icons package for this. Unfortunately it doesn't support linux only, and I don't have access to that OS. For macOS and windows, the icons have been updated. I used logo.png from the project itself. If you have this picture in a better resolution, let me know.

flutter_launcher_icons:
  windows:
    generate: true
    image_path: "assets/logo.png"
    icon_size: 48 # min:48, max:256, default: 48
  macos:
    generate: true
    image_path: "assets/logo.png"

Result ⬇️
