I want to turn an Int? into a String? but if the Int? is null I don't want to have a literal "null" String, I want the string value to be null. Is there an operator for this or do I have to check it manually?

null?.toString() == null

my mistake was somewhere else

I called toString() on that nullable String instead of orEmpty()
