Synchronization

Flutter / Dart

In Dart, the AtClient is stored within the AtClientManager. Once an atSign has been onboarded, you will be able to access the AtClientManager for its associated atSign.

AtClientManager

AtClientManager is a singleton model. When AtClientManager.getInstance() is called, it will get the AtClientManager instance for the last onboarded atSign.

AtClientManager atClientManager = AtClientManager.getInstance();

If you need simultaneous access to multiple atClients, you need to create a new isolate for each additional atClient, and onboard its atSign within the isolate.

An example of this pattern can be found in at_daemon_server.

SyncService

SyncService syncs the client app and remote secondary server’s changes:

• If the client app’s changes are ahead, it pushes the changes to the remote secondary.

• If the remote secondary is ahead, it pulls the changes to the client app.

You can retrieve the SyncService from the AtClientManager like so:

SyncService syncService = atClientManager.syncService;

Performing Syncs

To simply issue a sync, call the .sync function:

Other Clients

At this time, other clients do not support local persistence of the atServer, and thus do not require synchronization.

Future enhancements may enable support for your desired platform. If you require support, please file an issue on the appropriate GitHub repository:

• Java

• C/C++
