@override

  final builder = _copyQueryWith(columns: ['AVG($column)']);

  final completer = Completer<List<Map<String, dynamic>>>()
    ..complete(database!.rawQuery(builder.sql, builder.arguments));

  if (isLogger!) Logger.query(type, completer.future, builder);
  final result = await completer.future;

  return result.first.values.firstOrNull as double?;
