RecyclerViewAdapter.kt

 private val diffUtil = object : DiffUtil.ItemCallback<String>() {
        override fun areItemsTheSame(oldItem: String, newItem: String): Boolean {
            return oldItem == newItem
        }

        override fun areContentsTheSame(oldItem: String, newItem: String): Boolean {
            return oldItem == newItem
        }

    private val recyclerListDiff = AsyncListDiffer(this, diffUtil)

    var imageList: List<String>
        get() = recyclerListDiff.currentList
        set(value) = recyclerListDiff.submitList(value)
