I had started working on something similar (occasionally) here: https://github.com/jeremypw/gnonograms/tree/make-flatpak
That branch also makes some simplifications to make flatpaking easier. I think the main remaining problem was to get the theming right.
I am happy to merge this branch as the manifest is similar to the one in mine.
I'll make a draft PR of my branch for better visibility.
Thanks for the contribution @tintou !
