Feature request: Flatpak support

[okias]

Among the first Linux distributions which added support to Flatpak apps out-of-the-box were Endless OS,[15] Linux Mint,[16] Elementary OS,[17] Fedora Silverblue,[18][19] Zorin OS,[20] and Pop! OS.[21] Flatpak is also available for other distributions, including Ubuntu,[22] Red Hat Enterprise Linux,[23] OpenSUSE,[24] Arch Linux,[25] Debian,[26] CentOS,[27] Gentoo Linux,[28] Kubuntu,[29] Solus,[30] Alpine Linux,[31] Mageia,[32] Raspberry Pi OS,[33] Void Linux,[34] NixOS,[35] Pardus,[36] KaOS,[37] Zenwalk,[38] OpenMandriva Lx,[39] MX Linux,[40][41] PCLinuxOS,[42] Deepin,[43] Manjaro,[44] and PureOS[45]

I believe since it's huge coverage it would be amazing to have Cutter distributed also as flatpak.

I started working on such support. The latest work I saw around it ended in 2019 so I started over. You can follow it here. I would still need the maintainers approbation to publish it on flathub once it's done though.
