I don't think the package can be compatible with Fyne, or at least I couldn't find a way to be compatible with any other GUI frameworks (such as Gio). The reason is to be able to work with Android, it requires code to run on JVM, and this is a separate environment in Fyne compared to this package, which we use gomobile.
As far as I understood, this package implements the same clipboard functionality (copying text) as Fyne. If you only need Android/iOS support, Fyne's API set is probably enough for your use case: https://developer.fyne.io/api/v2.1/clipboard.html

Thank you, I just tested with gomobile it works, I think I will use another OpenGL framework.
