addGroupMembers method

void addGroupMembers(String groupId, { required List<String> membersToAdd, List<String> adminsToSet = const [], SealdGeneratedPrivateKeys? privateKeys, })

Adds members to a group. Can only be done by a group administrator. Can also specify which of these newly added group members should also be admins.

groupId - The group in which to add members. membersToAdd - The Seald IDs of the members to add to the group. adminsToSet - The Seald IDs of the newly added members to also set as group admins. privateKeys - Optional. Pre-generated private keys, returned by a call to SealdSdk.generatePrivateKeysAsync.

Implementation

        description: "Instance already closed.");
  }
