My question involves criminal record expunged for the state of: Florida

I was arrested on a charge of Grand Theft - $300 less than 5k. I admitted to it and turned myself in when they put a warrant out for my arrest. It was the only mistake I have ever made in my life. I am was extremely remorseful and embarrassed for the choices I made. I went to court and the judge withheld adjudication, and I completed my term of probation. I am getting my record expunged. My question is will this affect my chances of being a police officer? Up to the point of my mistake, I have never been in trouble with the law. I don't want this to be the defining choice in my life. I want to become a police officer and overcome my past. Thank you for your help.
