Should/will the error be removed in future Kotlin versions when using .not() ?

Variable val name is type “String?” and the argument name in requireName is type “String”. Change the argument name to type “String?” in the function requireName and code will be work.

I don’t want a nullable value in the function, sorry I meant requireName() can be any function

if you do not want a nullable value just use requireName(name!!) . Not the best...but it's going to work as you want

The question here is that isNullOrEmpty uses Kotlin Contracts and should be able to smart cast to String when returning false. This does not work when calling condition.not() which is equivalent to !condition.
