Viewpoint.withLatLongScale constructor

Viewpoint.withLatLongScale({
  1. required double latitude,
  2. required double longitude,
  3. required double scale,
})

Creates a viewpoint with latitude, longitude, and scale.

The spatial reference for the defined point is WGS84.

Parameters:

  • latitude — The latitude coordinate for the viewpoint. Negative values are south of the equator.
  • longitude — The longitude coordinate for the viewpoint. Negative values are west of the prime meridian.
  • scale — The ratio between a distance on the map and the corresponding distance on the ground.

Implementation

factory Viewpoint.withLatLongScale({
  required double latitude,
  required double longitude,
  required double scale,
}) {
  _initializeArcGISEnvironmentIfNeeded();
  final handle = _withThrowingErrorHandler((errorHandler) {
    return runtimecore.RT_Viewpoint_createWithLatLongScale(
      latitude,
      longitude,
      scale,
      errorHandler,
    );
  });
  return Viewpoint._withHandle(handle);
}
