Take a utility network offline | ArcGIS Maps SDK for Flutter

You can take certain utility network A utility network is a feature service that represents a utility system, such as water, gas, or electricity. A utility network provides the capabilities to visualize, edit, and analyze utility assets and data. Learn more information offline Offline is the state of having no network connection and applications cannot access ArcGIS Online or ArcGIS Enterprise. Learn more . Associations An association is a relationship between two elements that is reflected in a utility network topology. Learn more , which are used to describe containment, structural attachment, and connection between features with non-coincident geometry, can be queried and displayed with offline data Offline data is data that is generated and downloaded from a feature service, vector tile service, or image tile service for use in offline applications built with ArcGIS Maps SDKs for Native Apps.

Simple edits can also be made to utility network features while offline and synchronized back to ArcGIS Enterprise ArcGIS Enterprise is a GIS mapping, analytics, data hosting, and content management product that can be hosted on-premise or in a cloud infrastructure. It includes software, applications, tools, APIs, and services for users and developers. Learn more .

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.

    // Create an offline map task with the map.
    final offlineMapTask = OfflineMapTask.withOnlineMap(map);
    final offlineMapParameters =
        await offlineMapTask.createDefaultGenerateOfflineMapParameters(
      areaOfInterest: areaOfInterest,
    );

    // Create an offline map job with the download directory path and parameters
    final job = offlineMapTask.generateOfflineMap(
      parameters: offlineMapParameters,
      downloadDirectoryUri: Uri.parse(downloadDirectoryPath),
    );
    final result = job.result;
    if (result == null || result.offlineMap.utilityNetworks.isEmpty) return;
    // Get the utility network from the offline map.
    final utilityNetwork = result.offlineMap.utilityNetworks.first;

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
        .createDefaultGenerateGeodatabaseParameters(extent: areaOfInterest);
    geodatabaseParameters
      ..returnAttachments = false
      ..utilityNetworkSyncMode = UtilityNetworkSyncMode.syncSystemTables;

    // Create a generate geodatabase job.
    final geodatabaseJob = geodatabaseSyncTask.generateGeodatabase(
      parameters: geodatabaseParameters,
      pathToGeodatabaseFileUri: Uri.parse(pathToGeodatabaseFile),
    );

    // Start the generateGeodatabase job.
    geodatabaseJob.start();

    final output = geodatabaseJob.result;
    if (output == null || output.utilityNetworks.isEmpty) return;
    final utilityNetwork = output.utilityNetworks.first;
    debugPrint(utilityNetwork.name);
