It should, just put the analysis code in your header and it should work. The only problem is the verification, that you own the site. I don't have much experience with them, but there are several options how to verify that you own the page. I got analysis successfully working on my old Weebly (idk if i'm allowed to say the name, whatever, at worse some mod will just redact it) site, so I don't get why it wouldn't work on FreeFlarum (unless Google changed something).
