GeoModel class final
A base class for ArcGISMap and ArcGISScene that contains layers and
properties and can be displayed in a GeoViewController.
This base class represents the model in a model-view-controller (MVC) architecture, while the GeoViewController represents the view. To display a map or scene to the user, pass GeoModel to its appropriate GeoViewController, as follows:
- Pass an ArcGISMap to an ArcGISMapViewController.
- Pass an
ArcGISSceneto aSceneView.
GeoModel has many properties that are common to both maps and scenes. For example:
- Each map or scene typically has a GeoModel.basemap to help orient the users.
- The GeoModel.operationalLayers collection gives you access to the vector
data (points, line, polygons), raster data, and attribute information
provided by the ArcGISMap or
ArcGISScene. - The GeoModel.spatialReference determines how spatial data relates to real-world space.

getter/setter pair

-
The load error.
no setterinherited
- loadSettings ↔ LoadSettings
-
The properties that control the default loading and rendering behavior of
feature layers in this map or scene.
getter/setter pair

onBasemapChanged
→ Stream<
Basemap?> -
Callback invoked when the basemap changes.
no setter
-
onLoadStatusChanged

LoadStatus> -
A stream that reports changes to the
LoadStatus.no setterinherited -
operationalLayers
→ List<
Layer> -
A collection of layers that can access geographic data from a file or a
service.
no setter
- runtimeType → Type

-
The spatial reference for this map or scene.
no setter
-
tables
→ List<
FeatureTable> -
