here is my Implementation if you can help narrow down the issue please help

` private fun makeTypingText() {

    homeBinding.searchWriterView.setCharacterDelay(80)
    homeBinding.searchWriterView.animateText("Explore Deliciousness in Every Search..")


    homeBinding.searchWriterView.setOnAnimationChangeListener {
        Handler(Looper.getMainLooper()).postDelayed(Runnable {
            if (!this@HomeFragment.isDetached) {
                try {
                    if (index == 4) {
                        index = 0
                    }
                    index++

                    homeBinding.searchWriterView.animateText(makeTestList(index))
                }catch (e:Exception){
                    e.printStackTrace()
                }

            }
        }, 1500)
    }



}
val animatableText: ArrayList<String> = ArrayList()

private fun makeTestList(index: Int): String {
    if(animatableText.isEmpty()) {
        animatableText.add("Explore Deliciousness in Every Search..")
        animatableText.add("Find Flavorful Delights Here...")
        animatableText.add("Explore Deliciousness...")
        animatableText.add("Where Every Bite Speaks Flavor...")
        animatableText.add("Uncover Delicious Treasures Instantly...")
    }
    return animatableText[index]
