QueryDocumentSnapshot
class QueryDocumentSnapshot : DocumentSnapshot
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 the
data
property or by using subscript syntax to access a specific field.
A QueryDocumentSnapshot
offers the same API surface as a DocumentSnapshot
. As
deleted documents are not returned from queries, its exists
property will always be true and
data()
will never return nil
.
