Get users in group

Check whether a list of users belong to a target group using the OpenIM Flutter SDK.

Batch verify whether a specified set of users are members of a target group without loading full member profile records:

Parameters

Parameter	Type	Required	Description
`groupID`	`String`	Yes	Target group ID.
`userIDList`	`List<String>`	Yes	List of candidate user IDs to check.

Code example

final presentUserIDs = await OpenIM.iMManager.groupManager.getUsersInGroup(
  groupID,
  userIDList,
);

Return value

A successful Future returns a list containing only the user IDs that actively belong to the target group (List<String>).

This method performs a lightweight membership presence check; it does not return in-group nicknames, roles, or mute durations. To inspect detailed member profiles, see Get group members info.

This query returns an immediate data snapshot and does not emit event notifications.
