Map<String, dynamic> sanitizeCloudDataToSend(Map<String, dynamic> data, { required String? docId, bool hidePrivateFields = false, })

  Map<String, dynamic> data, {
  required String? docId,

  // Remove private fields.
  if (hidePrivateFields) {

      data.remove(field);
    }
  } else {
    // Late because it can potentially be unused;
    late final DateTime now = DateTime.now();

    data[SDKConstants.createdAt] =
        serializedCosmicValue(data[SDKConstants.createdAt] ?? now);
    data[SDKConstants.updatedAt] = serializedCosmicValue(now);

    if (docId != null) {
      data[SDKConstants.id] = docId;

    // Sort private fields to the bottom.
