You can take certain utility network information offline. Associations, which are used to describe containment, structural attachment, and connection between features with non-coincident geometry, can be queried and displayed with offline data. Simple edits can also be made to utility network features while offline and synchronized back to ArcGIS Enterprise.
The following code takes a web map offline that contains a utility network. The utility network tables are automatically synced with a map when a utility network is detected within.

The following code takes a utility network offline using a service geodatabase. The utility network tables only get synced when the sync mode in the generate geodatabase parameters is set to sync system tables.
// Create a geodatabase sync task with the feature service uri.
final geodatabaseSyncTask = GeodatabaseSyncTask.withUri(featureServiceUri);
await geodatabaseSyncTask.load();
// Create generate geodatabase parameters for the selected extents.
final geodatabaseParameters = await geodatabaseSyncTask
