clearMessages static method

Future<void> clearMessages(
  1. int? conversationType,
  2. String? targetId,
  3. dynamic finished(
    1. int? code
    )?
)

清空指定类型，targetId 的某一会话所有聊天消息记录

Implementation

static Future<void> clearMessages(int? conversationType, String? targetId, Function(int? code)? finished) async {
  if (conversationType == null || targetId == null) {
    developer.log("clearMessages fail: conversationType or targetId or content is null", name: "RongIMClient");
    return null;
  }
  Map paramMap = {
    "conversationType": conversationType,
    "targetId": targetId,
  };
  int? result = await _channel.invokeMethod(RCMethodKey.ClearMessages, paramMap);
  if (finished != null) {
    finished(result);
  }
}
