notify abstract method

@Deprecated("Use NotificationService") Future<bool> notify(AtKey key, String value, OperationEnum operation, { MessageTypeEnum? messageType, PriorityEnum? priority, StrategyEnum? strategy, int? latestN, String? notifier, bool isDedicated = false, })

Notifies the AtKey with the sharedWith user of the atsign. Optionally, operation, value and metadata can be set along with key to notify.

e.g alice is the current atsign
notify:update:@bob:phone@alice:[phone]
  var key = AtKey()..key='phone'
            ..sharedWith='@bob'
  var value='[phone]'
  var operation=OperationEnum.update
  notify(key, value, operation);
notify:update:ttl:60000:ttb:30000:@bob:phone@alice:[phone]
  var metaData = Metadata()..ttl='60000'
                 ..ttb='30000'
  var key = AtKey()..key='phone'
            ..sharedWith='@bob'
            ..metadata=metaData
  var value='[phone]'
  var operation=OperationEnum.update
  notify(key, value, operation);

var atKey = AtKey()..key = 'phone@alice'
                   ..sharedWith = '@bob'
                   ..sharedBy = ‘@alice’
Sending Notification with Notification Strategy ‘ALL’ and priority low
await atClient.notify(atKey, ‘[phone]’, OperationEnum.update,
                      priority: PriorityEnum.low,
                     strategy: StrategyEnum.all);

Sending Notification with Notification Strategy ‘Latest N’ and priority high
await atClient.notify(atKey, ‘[phone]’, OperationEnum.update,
                      priority: PriorityEnum.high,
                      strategy: StrategyEnum.latest,
                      latestN:3,
                      Notifier: ‘wavi’);
