sublayers property
The collection of sublayers of a sublayer.
This collection is usually empty unless the parent layer is loaded. Modifying this collection has no effect unless this sublayer is associated with an ArcGIS map service that supports dynamic layers. "Supports Dynamic Layers" must be set to true in the ArcGIS MapServer REST Services Directory.
Implementation
List<ArcGISSublayer> get sublayers => _sublayers.value;
