SystemLocationDataSource class final

A LocationDataSource that receives position data from the location services provided by the device's operating system. On iOS, location data is provided by CLLocationManager. On Android, location data is provided by the FusedLocationProviderClient included with Google Play Services, if available on the device. Otherwise, Android's LocationManager is used.

Use this data source to display location data on a map using the ArcGISMapViewController.locationDisplay.

Constructors

SystemLocationDataSource({int interval = 250, double distanceFilter = 0.0, DeviceLocationAccuracyType deviceLocationAccuracy = DeviceLocationAccuracyType.high})
Creates a system location data source. The interval is the interval in milliseconds at which location updates are requested (Android only). The distanceFilter is the distance filter in meters at which location updates are requested. The deviceLocationAccuracy is the desired accuracy for the location data provided by the device.

inherited
didChangeViewFocus(ViewFocusEvent event) → void
Called whenever the PlatformDispatcher receives a notification that the focus state on a view has changed.
inherited
didHaveMemoryPressure() → void
Called when the system is running low on memory.
inherited
didPopRoute() → Future<bool>
Called when the system tells the app to pop the current route, such as after a system back button press or back gesture.
inherited
didPushRoute(String route) → Future<bool>
Called when the host tells the application to push a new route onto the navigator.
inherited
didPushRouteInformation(RouteInformation routeInformation) → Future<bool>
Called when the host tells the application to push a new RouteInformation and a restoration state onto the router.
inherited
didRequestAppExit() → Future<AppExitResponse>
Called when a request is received from the system to exit the application.
inherited
enableBackgroundLocationUpdates(bool enableBackgroundUpdates) → void
Enables or disables the ability for the app to receive location updates when suspended.
handleCancelBackGesture() → void
Called when a predictive back gesture is canceled, indicating that no navigation should occur.
inherited
handleCommitBackGesture() → void
Called when a predictive back gesture is finished successfully, indicating that the current route should be popped.
inherited
handleStartBackGesture(PredictiveBackEvent backEvent) → bool
Called at the start of a predictive back gesture.
inherited
handleUpdateBackGestureProgress(PredictiveBackEvent backEvent) → void

inherited
setDeviceLocationAccuracy(DeviceLocationAccuracyType desiredAccuracy) → void
Sets the desired device location accuracy.
start() → Future<void>
Starts the location data source asynchronously and prepares to begin receiving location updates.
inherited
stop() → Future<void>
Stops the location data source asynchronously.
inherited
toString() → String
