From my understanding, Flatpak is built on top of OSTree, which will automatically deduplicate files across different packages. That said, I’m not sure if this extends to downloading packages. The site claims that it does do “delta updates,” which would hopefully mean that it doesn’t download files that are already on the system, even if they’re part of another package.
I’m just going off what I read in the docs. Someone with more understanding of the system can clarify.
