How can we get entire object list passes to the PagingDataAdapter while using Paging library 3.0?

Question

I am new to the paging library 3.0, I need to paginate data only from the local database. Initially, I fetched PagingSource<Int, MessageDisplayModel> from the database and use it as flow.

fun getChatMessages(chatWrapper: ChatWrapper): Flow<PagingData<MessageDisplayModel>> {
    return Pager(
            config = PagingConfig(pageSize = 15,
                    maxSize = 50,
                    enablePlaceholders = true)
    ) {
        xmppChatManager.getChatMessages(chatWrapper)
    }.flow
}

Then after PagingData is passing to the adapter through submitData() method.

lifecycleScope.launch {
        @OptIn(ExperimentalCoroutinesApi::class)
        mViewModel.getChatMessages(chatWrapper).collectLatest {
            adapter.submitData(it) }
    }

Now, my concern is how can we get the actual list of MessageDisplayModel from PagingData which I pass to the adapter?

You can use adapter.snapshot().items. More info can be found here.
