Are there any requirements for getting Darkrai when you go to the Pokemon event? - pokemon getting wedgies

I hope for is the Darkrai event in the U.S. May 31-June 1 This is my first go and I go and I wonder if they have to meet certain requirements in order to gain the same thing as the game or a certain amount of Pokémon see in your Pokédex get. If you attend an event, you can explain what I do when I buy at Toys R Us and (if applicable) I am eligible to do?
