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 🤔

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

Thanks @t-kameyama! It works as a charm!
