I have a function (
KtNamedFunction
) and I want to know if the returning type is Unit or not with type solving. I'm using this: 
function.bodyExpression.getResolvedCall(bindingContext)?.resultingDescriptor?.returnType?.isUnit()
but I get null for functions like this: 
fun asdf() = 5
. And if I use this: 
function.getType(bindingContext)?.fqNameOrNull()?.shortName()?.let { it.toString() == "Unit" }
get 
null
for 
fun asdf() {}
.

My gut feeling tells me the first one is the probably correct one 🤔

Copy code
override fun visitNamedFunction(function: KtNamedFunction) {
    val descriptor = bindingContext[BindingContext.DECLARATION_TO_DESCRIPTOR, function] as? FunctionDescriptor
    val isUnit = descriptor?.returnType?.isUnit()
}
