Geo View
GeoView is a base class for MapView and SceneView, these represent the View in a Model View Controller (MVC) architecture, the Map and Scene that are set on these views represent the model. It contains all of the common operations and events that apply to displaying and working with Maps and Scenes. This includes changing what is viewable area by setting a viewpoint, responding to viewpoint change events, working with graphics overlays and identifying elements that displayed at a given location in the view.

Types
The data class emitted from the GeoView.layerViewStateChanged SharedFlow.
Properties
The attribution text for the data that is currently displayed in the GeoView.
The GeoView's current draw status.
A collection containing the GraphicsOverlays.
True if attribution bar is visible in the GeoView, false otherwise.
Indicates whether the user is currently interacting with the GeoView.
Is the GeoView currently navigating.
True if the GeoView currently has wraparound turned on, false otherwise.
The view label properties. The view label properties are an overall control for whether labels will be created and displayed for layers added to the view. Individual layers can also control whether labels should be displayed for their features. Labels need to be enabled both in the view and in the layer. By default the labeling for a view is enabled. The view label properties also control global aspects of the label appearance e.g. animation effects.
Sets a callback to be invoked when the layer view state changes for the view.
A SharedFlow which emits a boolean to indicate that the navigation status of a GeoView has changed.
Called when the attribution bar's position or size changes due to expanding, collapsing, or inset changes.
A SharedFlow which emits DoubleTapEvent when the user double taps on the screen.
A SharedFlow which emits LongPressEvent when a user holds a pointer on the screen.
A SharedFlow which emits PanChangeEvent when a user drags a pointer or pointers across the screen.
A SharedFlow which emits RotationChangeEvent when a user performs a rotation gesture on the GeoView.
A SharedFlow which emits ScaleChangeEvent when a user performs a pinch gesture on the GeoView.
A SharedFlow which emits SingleTapConfirmedEvents when the user taps once on the screen.
A SharedFlow which emits TwoPointerTapEvent when a user taps two pointers on the screen.
The selection properties that is applied to the GeoView. This property allows configuration of new selection highlighting functionality such as selection promotion and switchable selection halo.
The SpatialReference is used to relate map coordinates to locations in the real world. This property is available when the view's map or scene has been loaded.
The current TimeExtent of the GeoView. The Time Extent of the GeoView defines how time-enabled data is displayed. Participating layers filter their data to only show data within the time extent set on the GeoView (see TimeAware for details). The range of the time extent includes the start and end values (a feature at 10/24/2016 would be included in a time extent defined as 10/24/2016 - 11/14/2016). Time filtering is not enabled until a non-null time extent is set on the GeoView. When the time extent is null on the GeoView, no time filtering is applied and all content is rendered.
A SharedFlow which notifies when the viewpoint of the view has changed.
