Online Message

Feature Description
In certain cases, you may want a message to be received by the receiver only when online; that is, the receiver won't notice the message when offline. You only need to set onlineUserOnly to true when calling sendMessage. A message sent in this way differs from a general one in that:
1. It cannot be stored offline; that is, it cannot be received if the receiver is offline.
2. It cannot be roamed across devices; that is, if it is received on a device, it cannot be received on another, whether it is read or not.
3. It cannot be stored locally; that is, it cannot be pulled from local or cloud historical messages.
Sample
Implementing the feature of "The other party is typing..."
In one-to-one chats, you can call the sendMessage API (Details) to send the prompt "I am typing...". After receiving the message, the receiver can display "The other party is typing..." on the UI.
Below is the sample code:
const data = 'Typing...';
const createCustomMessageRes =
      await TencentImSDKPlugin.v2TIMManager
          .getMessageManager()
          .createCustomMessage(data);
  TencentImSDKPlugin.v2TIMManager.getMessageManager().sendMessage(id: createCustomMessageRes.data.id, receiver: "", groupID: "",onlineUserOnly: true);
