QueryConstraint
abstractA QueryConstraint
is used to narrow the set of documents returned by a
Firestore query. QueryConstraint
s are created by invoking where,
orderBy, {@link (startAt:1)}, {@link (startAfter:1)}, {@link (endBefore:1)}, {@link (endAt:1)}, limit, limitToLast and
can then be passed to {@link (query:1)} to create a new query instance that
also contains this QueryConstraint
.
