sendMessage method

Future<V2TimValueCallback<V2TimMessage>> sendMessage({
  1. required String id,
  2. required String receiver,
  3. required String groupID,
  4. MessagePriorityEnum priority = MessagePriorityEnum.V2TIM_PRIORITY_NORMAL,
  5. bool onlineUserOnly = false,
  6. bool isExcludedFromUnreadCount = false,
  7. bool isExcludedFromLastMessage = false,
  8. bool needReadReceipt = false,
  9. OfflinePushInfo? offlinePushInfo,
  10. String? cloudCustomData,
  11. String? localCustomData,
})

发送消息 参数

id	消息唯一标识
receiver	消息接收者的 userID, 如果是发送 C2C 单聊消息,只需要指定 receiver 即可。
groupID	目标群组 ID,如果是发送群聊消息,只需要指定 groupID 即可。
priority	消息优先级,仅针对群聊消息有效。请把重要消息设置为高优先级(比如红包、礼物消息),高频且不重要的消息设置为低优先级(比如点赞消息)。
onlineUserOnly	是否只有在线用户才能收到,如果设置为 true ,接收方历史消息拉取不到,常被用于实现“对方正在输入”或群组里的非重要提示等弱提示功能,该字段不支持 AVChatRoom。
offlinePushInfo	离线推送时携带的标题和内容。
needReadReceipt 消息是否需要已读回执(只有 Group 消息有效,6.1 及以上版本支持,需要您购买旗舰版套餐)

Implementation

    {required String id, // 自己创建的ID
    required String receiver,
    required String groupID,
    MessagePriorityEnum priority = MessagePriorityEnum.V2TIM_PRIORITY_NORMAL,
    bool onlineUserOnly = false,
    bool isExcludedFromUnreadCount = false,
    bool isExcludedFromLastMessage = false,
    bool needReadReceipt = false,
    OfflinePushInfo? offlinePushInfo,
    String? cloudCustomData, // 云自定义消息字段,只能在消息发送前添加
    String? localCustomData}) async {
  return ImFlutterPlatform.instance.sendMessage(
      id: id,
      receiver: receiver,
      groupID: groupID,
      priority: priority.index,
      onlineUserOnly: onlineUserOnly,
      isExcludedFromUnreadCount: isExcludedFromUnreadCount,
      isExcludedFromLastMessage: isExcludedFromLastMessage,
      offlinePushInfo: offlinePushInfo?.toJson(),
      localCustomData: localCustomData,
