SystemLocationDataSource class final
A LocationDataSource that provides location updates from the device.
Use this data source to display location data on a map using the ArcGISMapViewController.locationDisplay.
When the start() function is called, the application will trigger a system location permissions dialog for the user if permission has not already been granted. For more granular control over when location permission is requested, consider integrating a permission handling package to request permission at any point within your application's workflow.
