Needed files for the packaging of RDM in Flatpak.
Check this Flathub's tutorial
wget https://raw.githubusercontent.com/flatpak/flatpak-builder-tools/master/pip/flatpak-pip-generator
chmod +x flatpak-pip-generator
rm pip-dependencies.json
./flatpak-pip-generator --requirements-file=/RDM/src/py/requirements.txt --output pip-dependencies
flatpak-builder build dev.rdm.RDM.json --force-clean
flatpak-builder --user --install build-test dev.rdm.RDM.json
flatpak run dev.rdm.RDM
For an unknown reason, the styles on the app are a bit buggy. Since I don't know that much about Qt nor Flatpak, I have asked the Flatpak KDE runtime developers for help.
See https://invent.kde.org/packaging/flatpak-kde-runtime/-/issues/20
Also, since my use of the app is quite simple (just locally) I haven't fully tested it.
