clearHistoryMessages static method

Future<void> clearHistoryMessages(
  1. int? conversationType,
  2. String? targetId,
  3. int recordTime,
  4. bool clearRemote,
  5. dynamic finished(
    1. int? code
    )?,
)

清除历史消息

conversationType 会话类型，参见枚举 RCConversationType

targetId 会话 id

recordTime 清除消息时间戳，【0 <= recordTime <= 当前会话最后一条消息的 sentTime,0 清除所有消息，其他值清除小于等于 recordTime 的消息】

clearRemote 是否同时删除服务端消息

finished 回调结果

此方法可以清除服务器端历史消息和本地消息，如果清除服务器端消息必须先开通历史消息云存储功能。例如，您不想从服务器上获取更多的历史消息，通过指定 recordTime 并设置 clearRemote 为 YES 清除消息，成功后只能获取该时间戳之后的历史消息。如果 clearRemote 传 NO，只会清除本地消息。

Implementation

static Future<void> clearHistoryMessages(int? conversationType, String? targetId, int recordTime, bool clearRemote, Function(int? code)? finished) async {
  if (conversationType == null || targetId == null) {
    developer.log("clearHistoryMessages error: conversationType or targetId null", name: "RongIMClient");
    return null;
  }
  Map map = {
    'conversationType': conversationType,
    'targetId': targetId,
    "recordTime": TypeUtil.getProperInt(recordTime),
    "clearRemote": clearRemote,
  };

  int? code = await _channel.invokeMethod(RCMethodKey.ClearHistoryMessages, map);
  if (finished != null) {
    finished(code);
  }
}
