A QueryDocumentSnapshot contains data read from a document in your Firestore database as part of a query. The document is guaranteed to exist and its data can be extracted with [data()] or [get()] to get a specific field.
A QueryDocumentSnapshot offers the same API surface as a DocumentSnapshot . Since query results contain only existing documents, the [exists] property will always be true and [data()] will never return 'undefined'.
