Implementation

  Map paramMap = {
    "conversationType": conversationType,
    "targetId": targetId,
    "keyword": keyword,
    "count": count,
    "beginTime": beginTime,
  };
  Map resultMap = await _channel.invokeMethod(RCMethodKey.SearchMessages, paramMap);
  int? code = resultMap["code"];
  if (code == 0) {
    List? msgStrList = resultMap["messages"];
    if (msgStrList == null) {
      if (finished != null) {
        finished(null, code);
      }
      return;
    }
    List l = [];
    for (String msgStr in msgStrList) {
      Message? m = MessageFactory.instance!.string2Message(msgStr);
      l.add(m);
    }
    if (finished != null) {
      finished(l, code);
    }
  } else {
    if (finished != null) {
      finished(null, code);
