getAdvancedHistoryMessageList method

Future<AdvancedMessage> getAdvancedHistoryMessageList({
  1. String? userID,
  2. String? groupID,
  3. String? conversationID,
  4. int? lastMinSeq,
  5. Message? startMsg,
  6. int? count,
  7. String? operationID,
})

获取聊天记录(以startMsg为节点，以前的聊天记录) userID 接收消息的用户id conversationID 会话id，查询通知时可用 groupID 接收消息的组id startMsg 从这条消息开始查询count条，获取的列表index==length-1为最新消息，所以获取下一页历史记录startMsg=list.first count 一次拉取的总数 lastMinSeq 第一页消息不用传，获取第二页开始必传 跟startMsg一样

Implementation

Future<AdvancedMessage> getAdvancedHistoryMessageList({
  String? userID,
  String? groupID,
  String? conversationID,
  int? lastMinSeq,
  Message? startMsg,
  int? count,
  String? operationID,
}) =>
    _channel
        .invokeMethod(
            'getAdvancedHistoryMessageList',
            _buildParam({
              'userID': userID ?? '',
              'groupID': groupID ?? '',
              'conversationID': conversationID ?? '',
              'startClientMsgID': startMsg?.clientMsgID ?? '',
              'count': count ?? 40,
              'lastMinSeq': lastMinSeq ?? 0,
              'operationID': Utils.checkOperationID(operationID),
            }))
        .then((value) =>
            Utils.toObj(value, (map) => AdvancedMessage.fromJson(map)));
