How to include Flatpak programs in custom ISO?

How to automatically include Flatpak programs and the Flathub repository in your custom ISO.

Already has -p "flatpak"

$ flatpak list

Google Chrome com.google.Chrome 139.0.7258.138-1 stable system
Epson Scan 2 net.epson.epsonscan2 6.7.65.0 stable system

Would it be with -I?

Copy the Flatpak programs installed on your computer and replicate them on the ISO [METHOD]

Copy /var/lib/flatpak and ~/.local/share/flatpak

$ ls /var/lib/flatpak/
app appstream exports repo runtime

$ ls ~/.local/share/flatpak/
db overrides repo

Permissions may break, and different versions may cause errors.

sudo rsync -a /var/lib/flatpak include/var/lib/

rsync -a ~/.local/share/flatpak include/include/etc/skel/.local/share/

Update the registries with flatpak repair or flatpak update upon startup.

Does this work on the ISO you created?

Is there a way to test it...
