If a girl calls you sweetheart what does that mean?

Anonymous
not like "he's a sweetheart" but like her saying "OK sweetheart have a good night".

if/when you say this to a guy, is there any implication of flirting? I ask because this girl I kept seeing at a store on multiple occasions said something like that to me. we did smile a lot and I felt something from it but I tried not overdoing it and seeming creepy lol. it wasn't the type of job where she could get tips or anything either. just wondering if I should go back and try to talk or if its a waste of time haha
