With paging2 and the PagedListAdapter, I was simply checking if the list was empty before sending it to the adapter so I wasn't handle it with the adapter (which is probably wrong).
I tried to migrate to paging3 but I couldn't because I don't know how to check if the list is empty, as the PagingData that we send to the new adapter doesn't expose the list or an isEmpty method.

To be clear, adapter.itemCount will only work if placeholdersEnabled is false.
We held off on this change because we wanted to take some time to properly explore what it would look like to provide a public API to view the PagingState or the internal PageEvent stream, but it's clear there's immediate need for this.
In the meantime, here's an idea for a CL which adds a Boolean to dataRefreshFlow, which we could merge for alpha02:
