Great advice here and please reassure both your DD and yourself that this is totally normal. She may or may not grow out of this but it is sometimes she will get used to. I have four children, one was like this and it was horrendous and she never liked school, much worse for Mummy though than the child especially as once DD is out of sight child is fine.
I’m with the quick hug quick departure advice
Good luck
