Flatpak Package

Hello,
I created a Flatpak<https://flatpak.org/> package for GNU Smalltalk.  I could not test it much (since I don't really know Smalltalk) but it can print "Hello World" and create a GTK+ window with a button. If you are interested, you can check it at https://gitlab.com/cagatay-y/org.gnu.Smalltalk and download<https://gitlab.com/cagatay-y/org.gnu.Smalltalk/-/jobs/artifacts/master/download?job=flatpak_bundle> the bundle. You can submit issues for bugs related to packaging and I will try to fix them.
If it is working, I plan to submit the package to Flathub. However, Flathub prefers the submitter to be the maintainer of the app. Are any of the maintainers interested? I think having a Flatpak package on Flathub would be great for the project, as it will simplify its installation for all distributions.

Regards,
