Flatpak packaging

[MateusRodCosta]

So, OpenFusion now has an official Linux version, which is great!

I believe then that it could benefit from being packaged as a flatpak and distributed on Flathub.

One of the requirements is that somebody who plans to package for flathub should let upstream know.

A few of the benefits from adding an app to flathub:

• Consistent way of distributing an app to several Linux distros
• App sandboxing (might not be as useful depending on application)
• Higher visibility (for example, flathub is shipped on Steam DEk by default)
• Some improved system integration.

I believe I can package but might have a few issues if the game writes inside its own folder.

This is something we plan to tackle once we iron out other Linux specific issues, as asking the user to install dependencies (especially on an immutable distro like SteamOS) isn't ideal.

I'll try to keep this issue updated with any progress.

If your concern is Wine and possibly Electron, then basing on the itch work could help: https://github.com/flathub/io.itch.itch/blob/master/io.itch.itch.yaml

Preferably we would use system Wine, but I'm not sure how possible that is with Flatpak's sandboxing. Maybe an AppImage would be better in this scenario.

OpenFusionLauncher uses Tauri so Electron would not be a concern.
