Implementation

    json["custom"] = {"custom": json["custom"]};
  } else {
    final Map<String, dynamic> custom = {};
    json["custom"] = custom;
  }

  final t = innerFromJson(json);

  json.forEach((key, value) {
    if (key != "custom" && !builtInKeys.contains(key)) {
      t.custom[key] = value;
    }
  });
  return t;
