While most people named Dexter are male, it's not unheard of as a girl's name, for instance Diane Keaton's daughter is named Dexter Dean.
In fact, originally one Old English meaning of Dexter was as a "women who dyed cloth." But it also coincides with the Latin word dexter meaning "right-handed, skilled". In this case, dexter referred to the right side (and more favorable) side of a shield or coat of arms.
