Sorting using createdBy attribute

[MerNat]

Is there a way to sort out a query by the attribute of createdBy as I'm trying to get the newly added items first in my result?

Any suggestion or idea on how to add the setting/subquery to this statement:

      AlgoliaQuery _query = _algolia.instance
          .index("text-index")
          .setPage(startingKey!)
          .setHitsPerPage(pageSize);

AlgoliaQuery _query = _algolia.instance
.index("text-index")
.setPage(startingKey!)
.setHitsPerPage(pageSize)
.setSettings({
'customRanking': ['desc(createdBy)']
});
