android - How to use DiffUtil with RecyclerView containing list of StorageReferences

Question

I have a list containing StorageReferences from Firebase Storage. I want to display this list in a RecyclerView with DiffUtil.

I am thinking of doing this:

val DIFF_CALLBACK: DiffUtil.ItemCallback<StorageReference> =
            object : DiffUtil.ItemCallback<StorageReference>() {
                override fun areItemsTheSame(
                    oldStorageReference: StorageReference, newStorageReference: StorageReference
                ): Boolean {
                    return oldStorageReference == newStorageReference
                }

                override fun areContentsTheSame(
                    oldStorageReference: StorageReference, newStorageReference: StorageReference
                ): Boolean {
                    return true
                }
            }

I just return true on the areContentsTheSame since I read here that it is only called if areItemsTheSame, in which I already checked their equality, returns true.

Is this correct? Is there a better way to do this?
