'How to know when a Lottie animation is completed?

I have a fragment, here is the onCreateView method:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    
    // Inflate the layout for this fragment
    mView = inflater.inflate(R.layout.fragment_added_to_cart_anim, container, false);
    ButterKnife.bind(this, mView);

    mAddedToCartAnimation.setAnimation("checked_done_.json");
    mAddedToCartAnimation.loop(false);
    mAddedToCartAnimation.playAnimation();

    // Remove fragment when the animation is finished.

    return mView;

}

I need to remove the fragment using getActivity().getSupportFragmentManager().beginTransaction().remove(this).commit(); when the lottie animation has ended. If I understand correctly when the isAnimating() Lottie method returns false the animation has ended and since in my configuration the animation does not loop this is when I should remove the current fragment. But I can't just use an if statement since when it is executed the animation may still be going.

I need a way to remove the fragment when the Lottie animation ends, how do I do this?

Kotlin Code for animation complete :

successAnimation.addAnimatorListener(object : Animator.AnimatorListener{
            override fun onAnimationRepeat(animation: Animator?) {
            }

            override fun onAnimationEnd(animation: Animator?) {
                //Add your code here for animation end
            }

            override fun onAnimationCancel(animation: Animator?) {
            }

            override fun onAnimationStart(animation: Animator?) {
            }

        })

In Kotlin , you can this way:

val lotWelcome=findViewById<LottieAnimationView>(R.id.lot_1) 
   
lotWelcome.addAnimatorListener(object : Animator.AnimatorListener {
       override fun onAnimationStart(animation: Animator) {
           Log.e("Animation:", "start")
       }
   override fun onAnimationEnd(animation: Animator) {
       Log.e("Animation:", "end")
       //Ex: here the layout is removed!
       firstScreen.visibility= View.GONE
   }

   override fun onAnimationCancel(animation: Animator) {
       Log.e("Animation:", "cancel")
   }

   override fun onAnimationRepeat(animation: Animator) {
       Log.e("Animation:", "repeat")
   }

  })
