Fyne (https://developer.fyne.io/started/packaging) proposes a solution for packaging apps:
fyne package -os darwin -icon myapp.png
And another method for cross-compiling: https://developer.fyne.io/started/cross-compiling
I was wondering if there is a way to combine both, for instance to cross-compile and package a Fyne app on a Mac M1 for a Mac AMD.
