[CC-Hsu]

What would you like to happen?

Hi, Team,

Flatpak is a sandbox desktop environments that can ship software without too much dependency burdon.

It may be great to package into Flatpak sandbox and distribute in Flathub and provide more way to attract users.

And there are some samples that package Java-based software into it.
