you can use nix-software-center by vlinkz

I don't plan on it at this moment, however, if someone finishes the packagekit backend for Nix, the appstream data I'm working on collecting would work to display icons and screenshots. Also if someone who knew qt/kirigami development wanted to make something similar to nix-software-center, the backend tool that reads and modifies configuration values is a separate project: nix-editor, and I would be willing to help with any issues that arose from that.

Thanks for reply! I'm trying to install via configuration.nix . I haven't migrated to flakes but maybe I use some of them unknowingly? Here is my own configuration.nix. The error I get when running instructions for building via sudo nixos-rebuild boot:
