Note:

3. The original message object used to create a targeted group message cannot be a group @ message.
4. The targeted group message feature is unavailable for communities (Community) and audio-video groups (AVChatRoom).
5. By default, targeted group messages are excluded from the unread count of a group conversation.

Sending a Targeted Group Message

A targeted group message is a message sent to specified members in a group, which cannot be received by unspecified group members. It can be implemented in the following steps:
1. Call the createXXXMessage API (here, XXX indicates the message type) to create an original message object V2TIMMessage.
2. Call the createTargetedGroupMessage API (Details) to create a targeted message object V2TimMessage based on the original message object and specify the list of group members to receive the message.
3. Call the sendMessage API to send the targeted message.
Sample code:
// Create a message first
  V2TimValueCallback<V2TimMsgCreateInfoResult> target = await TencentImSDKPlugin.v2TIMManager.getMessageManager().createTextMessage(text: "");
  // Get the ID for sending a message
  String id = target.data.id;
  // Create a targeted message
  V2TimValueCallback<V2TimMsgCreateInfoResult> groupTarget = await TencentImSDKPlugin.v2TIMManager.getMessageManager().createTargetedGroupMessage(id: id, receiverList: ['user1','user2'],);
  // Send the message
  TencentImSDKPlugin.v2TIMManager.getMessageManager().sendMessage(id: groupTarget.data.id, receiver: "", groupID: "groupID");

Receiving a Targeted Group Message

By default, targeted group messages are excluded from the unread count of a group conversation. A targeted group message can be received in the same way as an ordinary message. For detailed directions, see Receiving Message.
