FeatureCollectionTable class final

A feature collection table represents an individual feature table in a FeatureCollection.

A FeatureCollectionTable consists of a feature definition (table schema) and a set of features that match that feature definition. You can obtain a FeatureCollectionTable from an existing FeatureCollection.tables collection or you can create a new FeatureCollectionTable programmatically in your app.

To create a new FeatureCollectionTable, you can use a constructor that defines a set of fields, the geometry type, and spatial reference, and then populate it by adding new features. Alternatively, you can create a new FeatureCollectionTable from a FeatureSet, such as the FeatureQueryResult returned from a FeatureTable.queryFeatures.

To render the features in a map or scene, add the FeatureCollectionTable to a FeatureCollection.tables collection, construct a FeatureCollectionLayer from the FeatureCollection, and add it to the map or scene's collection of operational layers. To specify the FeatureCollectionTable symbology, just apply a renderer to the FeatureCollectionTable.renderer. If required, you can override this symbology on a per-feature basis using the FeatureCollectionTable.setSymbolOverride.

Constructors

FeatureCollectionTable({required List<Field> fields, required GeometryType geometryType, SpatialReference? spatialReference, bool hasZ = false, bool hasM = false})
Creates an empty FeatureCollectionTable from the specified fields, geometry type, spatial reference. The table can contain z and m values.
factory
FeatureCollectionTable.withFeatureSet(FeatureSet featureSet)
Creates a FeatureCollectionTable populated from the specified FeatureSet.
factory
FeatureCollectionTable.withGeoElements({required List<GeoElement> geoElements, required List<Field> fields})
Creates a FeatureCollectionTable populated from the specified GeoElement collection.
