How I can retrieve current fragment in NavHostFragment?

Question

I tried to find a method in the new Navigation components but I didn\'t find anything about that.

I have the current destination with :

mainHostFrag

Using Michal's answer I wrote this extension function for testing:

@Suppress("UNCHECKED_CAST")
fun  AppCompatActivity.getFragment(fragmentClass: Class): F? {
    val navHostFragment = this.supportFragmentManager.fragments.first() as NavHostFragment

    navHostFragment.childFragmentManager.fragments.forEach {
        if (fragmentClass.isAssignableFrom(it.javaClass)) {
            return it as F
        }
    }

    return null
}

Used like this:

val myFragment = activity.getFragment(MyFragment::class.java)
