one<T> method

@override Future<T?> one<T>(String documentID, { String? subcollection, })

Reads a document from Localstore and converts it to the specified type.

Implementation

@override
Future<T?> one<T>(String documentID, { String? subcollection }) async {
  final deserializer = LS.deserializers[T];
  if (deserializer == null) {
    throw UnsupportedError('No deserializer found for type: $T. Consider re-generating Firestorm data classes.');
  }

  DocumentRef ref = LS.instance.collection(T.toString()).doc(documentID);
  if (subcollection != null) {
    ref = LS.instance.collection(T.toString()).doc(subcollection).collection(subcollection).doc(documentID);
  }

  Map<String, dynamic>? snapshot = await ref.get();
  if (snapshot == null) {
    return null;
  }
  T object = deserializer(snapshot) as T;
  return object;
}
