You can manage your app icon in Nylo from the
/public/assets/app_icon directory. We understand that generating all the required dimensions for your app icon can be a laborious task so we have provided a command you can run using our
Metro Cli tool to auto-generate all your (iOS and Android) icons for you.
Your app icon should be a
.pngwith the size dimensions of 1024x1024px
If you have custom icons for different operating systems you can also just add them manually. This guide will be useful for those needing a tool to build their icons for them.
Nylo uses the flutter_launcher_icons library to build these icons, to understand the library more you can check out their documentation too.
