        val frgment = MyFragment().getInstance()
        frgment?.buttonClick()
    }

MyFragment.kt Code

fun getInstance(): MyFragment? {

        Log.e("Fragment", "FirstName $value")
}

Can anybody help me about it? I don't want to use Listner

What you just did is that you created a new instance of the fragment instead of getting the instance of the current active fragment, that is why you are getting a null. You can use FragmentManager to get a fragment by tag or Id

MyFragment myFragment = (MyFragment)getSupportFragmentManager().findFragmentByTag("MY_FRAGMENT");
