extensions property
The collection of extension licenses for the app.
For valid extension license keys supplied when calling ArcGISEnvironment.setLicenseUsingKey, this collection is populated with information about the extension licenses. Use this function to iterate extension licenses available for the app.
Note that, although this collection is empty when running an app in developer mode, all extension licensed functionality will be available.
Implementation
List<ExtensionLicense> get extensions => _extensions.value;
