They had a BTTF reference in the Flash season 3 episode 1 Flashpoint. Here is what the arrow verse wiki said about it. The way that Barry explains "Flashpoint" resembles a scene in Back to the Future: Part II where Doc Brown explains how alternate 1985 happened. The design drawn by Barry is the exact same design drawn by Doc on his blackboard in the scene from that movie.
