getLocalizedDisplayname method

String getLocalizedDisplayname([ SDNLocalizations i18n = const SDNDefaultLocalizations() ])

Returns a localized displayname for this server. If the room is a groupchat without a name, then it will return the localized version of 'Group with Alice' instead of just 'Alice' to make it different to a direct chat. Empty chats will become the localized version of 'Empty Chat'. This method requires a localization class which implements SDNLocalizations
