Send a message

Use the Flutter SDK to send a prepared message object.

Copy
final sent = await OpenIM.iMManager.messageManager.sendMessage(
  message: message,
  userID: receiverUserID,
  offlinePushInfo: offlinePushInfo,
);

For a one-to-one message, set only userID; for a group message, set only groupID. A message sent with isOnlineOnly is not stored in ordinary history. The Future returns the server-confirmed Message. Confirm that its clientMsgID is non-empty before replacing the local pending item.
