So I used https://github.com/franzsilva/flutter_launcher_icons to generate the icons for my flutter project- which was pretty sweet, thank you very much.
Trying to create the IOS app, I got this error:
project/ios/Runner/Assets.xcassets: error: None of the input catalogs contained a matching stickers icon set or app icon set named "Icon-App".
I have very little knowledge of iOS development, so I have no idea what is going on.
