Implementation

String toJsonString() {
  final Map<String, dynamic> map = {};
  map['Channel'] = channel;
  map['StreamType'] = streamType;
  map['BeginTime'] = beginTime == null
      ? DateUtil.formatStartOfDay(beginTime)
      : DateUtil.formatDateTime(beginTime!);
  map['EndTime'] = endTime == null
      ? DateUtil.formatEndOfDay(endTime)
      : DateUtil.formatDateTime(endTime!);
  map['FileName'] = '';
  return json.encode(map);
