Unchecked function

:1234: Code to reproduce

:computer: Environment

Hi, I used to use the ERC721 now I'm using Ugradeable version. I'm having a hard time with the Counters library using the Unchecked method. I can't find much documents on it, Would someone be able to tell me how unchecked method works?

Not sure I understand the question. What do you mean by "the unchecked method"?
