Is supergirl part of the dc extended universe?

The DC Extended Universe (DCEU) is a shared film universe that began with Man of Steel in 2013 and has included characters such as Superman, Batman, and Wonder Woman. The provided Wikipedia information lists these characters as part of the DCEU but does not mention Supergirl. Because the evidence does not confirm Supergirl’s inclusion, it cannot be stated that she is part of the DCEU without further verification. Additional research would be needed to determine if any DCEU film features Supergirl.
