The FeatureSnappingLayerSource specifies which layers will be utilized for snapping in the SnappingOptions.
Known Limitations
- Layer types currently supported for snapping are: FeatureLayer, GraphicsLayer, GeoJSONLayer, WFSLayer, CSVLayer, MapNotesLayer (2D only), 3D Object SceneLayer (3D only), and BuildingSceneLayer (3D only).

// Create a new instance of Sketch, and set
// a layer for one of the featureSources property.
// This enables feature snapping on that layer.
const Sketch = new Sketch({
layer: graphicsLayer,
view: view,
snappingOptions: { // autocasts to SnappingOptions()
enabled: true, // global snapping is turned on
// assigns a collection of FeatureSnappingLayerSource() and enables feature snapping on this layer
featureSources: [{ layer: graphicsLayer, enabled: true }]
}

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.
// Manually manage handles const handle = reactiveUtils.when( () => !view.updating, () => { wkidSelect.disabled = false; }, { once: true } ); this.addHandles(handle); // Destroy the object this.destroy();ParametershandleOrHandles WatchHandle|WatchHandle[]Handles marked for removal once the object is destroyed.
groupKey *optionalKey identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.
