Use case

You might use a geocoder to find a customer's delivery address based on the location returned by their device's GPS.

How to use the sample

Tap the map to see the nearest address displayed in a callout.

How it works

Create a LocatorTask object using a URL to a geocoder service.
Set the GeocodeParameters for the LocatorTask and specify the geocoder's attributes.
Get the matching results from the GeocodeResult using LocatorTask.reverseGeocodeAsync.
Show the results using a PictureMarkerSymbol and add the symbol to a Graphic in the GraphicsOverlay.
