$find<R extends FirestoreEntity<R>> method

Future<R?> $find<R extends FirestoreEntity<R>>({ Query<R> query(Query<R> query)?, })

Finds the first R entity in the corresponding subcollection of this entity matching the query. Returns null if no entity was found.

Implementation

Future<R?> $find<R extends FirestoreEntity<R>>({Query<R> Function(Query<R> query)? query}) async {
  var subCollection = getSubCollection<R>();
  Query<R> q = subCollection;
  if (query != null) {
    q = query(q);
  }
  var snapshot = await q.get();
  if (snapshot.size == 0) return null;
  return snapshot.docs.first.data();
}
