many<T> method

@override Future<void> many<T>(List<T> objects, { String? subcollection, })

Deletes multiple documents from Firestore using a list of objects.

Implementation

@override
Future<void> many<T>(List<T> objects, { String? subcollection }) {
  if (objects.isEmpty) return Future.value();
  if (objects.length > 500) {
    throw ArgumentError('Batch delete limit exceeded. Maximum 500 objects allowed.');
  }

  final String? className = LS.classNames[objects[0].runtimeType];
  if (className == null) {
    throw UnsupportedError('No class name found for type: ${objects[0].runtimeType}. Consider re-generating Firestorm data classes.');
  }

  List<Future<void>> futures = [];
  for (dynamic object in objects) {
    if (object.id == null) {
      continue; //skip
    }
    DocumentRef ref = LS.instance.collection(className).doc(object.id);
    if (subcollection != null) {
      ref = LS.instance.collection(className).doc(subcollection).collection(subcollection).doc(object.id);
    }
    futures.add(ref.delete());
  }
