We also support development using Flatpak via GNOME Builder. At the Builder "Clone..." dialog, enter https://gitlab.gnome.org/GNOME/meld.git, and the default build + run development flow using Flatpak should work.
Meld uses GNOME's GitLab to track bugs, and user questions and development discussions happen on the Meld mailing list. The development team is small, and new contributors are always welcome!
