For all the “real” Electron apps I’ve looked at, the flatpak version is just a wrapper around the upstream deb file. Are there any that are actually built from source?
Following because I also could not figure this out last time I tried.
IMHO after Flatpak’s new beta comes out, the next best thing would be improved packager experience. It’s so hard to package Python/.NET/etc apps because of how dependencies are handled and how you have to run random scripts.
Flatpak has always had great user UX, but the packager side is lacking the same love. The people who review Flathub submissions (bless them) are probably feeling the side effect of that every single day, since way too many submissions have issues.
