I’ve heard that there is an animated series featuring The Flash as the main character and am interested in seeing it, is there any chance that it will be on the DC Universe sometime soon? I think it might have been made in 2014, but I’m not sure. Also, yes I know about the live-action Flash tv series.
There is no animated series entirely focused on the Flash that I know of. Is it possible that you’re thinking of Justice League: The Flashpoint Paradox, the animated movie released in 2013? It, being animated and focused on the Flash, is the closest thing I can think of to the year you mentioned. Somebody else may have a better idea though. Or there may be a Flash show I’ve never heard of.
Flash is one of the main characters on Justice League. That could be what you are looking for.
