Set toolbar title dynamically using navigation-component

Question

I\'m trying to set the toolbar title dynamically, I don\'t know if it\'s possible or not.

Assume I have list of items every item I clicked it\'s open new fragment,

Answer 1

you can add a method for updating the fragment title and call it in fragment onStart() method

fun updateToolbarTitle(title: String) {
    supportActionBar?.title = title
}

and remove lable attribute from tag in your nav_graph.xml so it'll be like that
