Set group extension

Attach custom business extension strings to a group. The ex field is a plain text string that overwrites existing data; if managing structured data like JSON, fetch existing values first, merge attributes in the application layer, and submit the complete serialized string:

Parameters

Code example

await OpenIM.iMManager.groupManager.setGroupInfo(
  GroupInfo(
    groupID: groupID,
    ex: mergedExtensionJSON,
  ),
);

Return value

A successful Future indicates that the extension string has been updated on the server.

State changes after the call

The server broadcasts group profile update notifications. The client updates ex on the local group record using groupID as the key. For complete listener integration, see Groups overview. To recalibrate group state, call Get specified groups info.
