setCurrentAtSign method

Future<AtClientManager> setCurrentAtSign(String atSign, String? namespace, AtClientPreference preference, { AtServiceFactory? serviceFactory, AtChops? atChops, String? enrollmentId, })

• Can provide an AtServiceFactory to control what types of AtClients, NotificationServices and SyncServices get created by this method.
• Can provide an AtChops instance if available; setCurrentAtSign will ensure that it is injected into objects that can use it

Implementation

  secondaryAddressFinder ??= CacheableSecondaryAddressFinder(
      preference.rootDomain, preference.rootPort);

      _currentAtClient?.getCurrentAtSign() == atSign) {
    _logger.info(
        'previous currentAtSign ${_currentAtClient?.getCurrentAtSign()} is same as new atSign $atSign - doing nothing, returning');
