The folks here are mostly following / working on core FLTK and are not involved with side projects such as pyFLTK.
The pyFLTK home page is at
https://pyfltk.sourceforge.io/ and the project files on
SourceForge. The last posted news is dated December 23, 2021, but I see that the maintainer made a commit just a couple of weeks ago, so the project appears active.
They have a mailing list (link on the homepage above), that would be the first place I'd try...
