update<T> method

Future<void> update<T>(
  1. List<T> objects, {
  2. String? subcollection,
})

Updates objects in the RDB using a single operation.

Implementation

Future<void> update<T>(List<T> objects, { String? subcollection }) async {
  Serializer? serializer = RDB.serializers[T];
  if (serializer == null) {
    throw UnsupportedError('No serializer found for type: $T. Consider re-generating Firestorm data classes.');
  }

  final Map<String, dynamic> updates = {};

  //For each object, serialize it, and then add it to the list of updates:
  for (var object in objects) {
    var map = serializer(object);
    if (map["id"] == null || map["id"].isEmpty) {
      throw NullIDException(map);
    }
    String path = RDB.constructPathForClassAndID(object.runtimeType, map["id"], subcollection: subcollection);
    updates[path] = map;
  }

  await RDB.instance.ref().update(updates);
}
