Reference documentation and code samples for the Firestore v1 API class DocumentChange.
A [Document][google.firestore.v1.Document] has changed.
May be the result of multiple [writes][google.firestore.v1.Write], including

Multiple [DocumentChange][google.firestore.v1.DocumentChange] messages may be
