When to drop the CF-bomb?

I’m heading into the dating world again with a new-found solidity of not wanting to have kids. I just want to know how/when all you singletons bring about that type of conversation to your prospectives? I guess it’s certainly never too soon to talk about it theoretically, but just as if someone started talking about kids/marriage to me on a first date, I would find it a bit pushy barely knowing someone else. I’m assuming there’s probably a sweet spot. Let’s also assume it’s not by app where you could just write it in your profile ahead of time
