fetch method
Future<T>
fetch({
- required DocumentReference<
Object?> ref, - Source source = Source.serverAndCache,
Same as RepositoryAddon.transform but will return a Future with
latest value in the DB using the given ref
.
If the given ref
is not found, this will throw an exception.
Implementation
Future<T> fetch({
required DocumentReference ref,
Source source = Source.serverAndCache,
}) async {
final snapshot = await ref
.withConverter(
fromFirestore: _repo.fromSnapshot, toFirestore: _repo.toMap)
.get(GetOptions(source: source));
final data = snapshot.data();
if (data == null) {
throw Exception("No document exists in the Ref: ${ref.path}");
}
return data;
}
