How to lazy pass in parameters for singleton?

[DanMossa]

Hello!

I have a class with a constructor that takes a String.

I want this to be a singleton.

I also won't have the String to pass in during app startup.

How can I register a singleton that has a constructor and then pass in the parameters when getting that singleton?

I'm thinking maybe a factory singleton?

Looking more into it, this seems like an anti pattern.

I'll have to change something about my architecture.
