Flatpak request

[Alexey Skobkin]

I saw that Flatpak was also requested in #34, but it wasn't implemented, so I'm leaving this feature request here.
Flatpak is available on some platforms where store app does not support backends like Snap or AppImage.
Good example is SteamOS 3 on Steam Deck where only Flatpak is available.

[Dmitry Sidorov]

AppImage should work on SteamOS

[Alexey Skobkin]

It works, but it's not installable via Discover and couldn't be auto-updated there.

[Dmitry Sidorov]

Well that makes sense. Although I was somewhat hopeful that the person in that issue would package. It will take me some time to get to grips with flatpack, as I'm not really a snap or flatpack amateur.

[Dmitry Sidorov]

It seems to be working.

Nice!

Will it be available on Flathub when you're sure that it's working totally fine?

[Dmitry Sidorov]

Yes, need to read application requirements, hope --filesystem=host is allowed to use.

[Dmitry Sidorov]

Honestly, I don't really understand what they want. If anyone understands this, you are welcome to do so.

[Alexey Skobkin]

It looks like they want you to either change the app-id to something github-related or register a domain for your app.

https://docs.flatpak.org/en/latest/conventions.html#application-ids

io.github.Foo This is problematic because while foo.github.io may be unique to your project, it does not include a project-specific identifier. This may cause issues if another project creates io.github.Foo-Bar which should be its own namespace but areas of flatpak may treat them similar. A better ID would be io.github.foo.Foo even if it is redundant.

Thank you, that makes more sense. It's curious the documentation is scattered all over the place.

[Dmitry Sidorov]

You can try to check it: flatpak install flathub io.github.jonmagon.kdiskmark works for me fine.

[Alexey Skobkin]

Yes, I've tried on the Steam Deck and also on my desktop PC (Gentoo). Both worked fine. At least at a first glance.

Thank you!
