Linkedlist, unidirectional or bidirectional?

Question

Kotlin

If you type linked list kotlin or linked list java, then they usually write about a doubly-directed list, but if you go to the pictures, then there are both unidirectional and bidirectional ones, it’s also not clear in the class implementation where to look, you can see the implementation of adding, searching, but where exactly is it described creating an object and storing links to the previous and next element, I can’t find how to understand whether it is bidirectional or unidirectional?
