As I've seen a few recent posts on this topic, I thought I should clarify something. This wiki doesn't cover Stargirl. It's off topic content. Same with the DCEU and other DC franchises only loosely connected. Only ones we have covered are Birds of Prey, (The 2002-2003 series) The Flash, (1990-1991) and Constantine. Of course we also have the other Arrowverse shows you know of like Arrow, The Flash, (2014-Now) Supergirl, Legends of Tomorrow, Vixen, Freedom Fighters, and Batwoman. Along with the upcoming Superman and Lois.
There is a wiki for Stargirl for your convenience.
