PagerList error while Creating config File

Question

My android Studio is striking off the PagedList as it says it migrated to paging data

private fun setUpAdapter() {




    val config = PagedList.Config.Builder()
        .setEnablePlaceholders(false)
        .setPageSize(10)
        .setPrefetchDistance(2)
        .build()

    val options = FirestorePagingOptions.Builder<User>()
        .setQuery(database,config,User::class.java)
        .setLifecycleOwner(this).build()
