map	a map widget
provider	A provider list object created with e.g. geosearchProvider
options	A list of control options created with geosearchOptions.

Shiny value

When used inside a Shiny application, addGeosearch() will also register two reactive inputs that return the most recent geosearch results:

• input$<mapId>_geosearch_result Updated when a search result is selected (from the geosearch/showlocation event). Returns a list with lat, lng, label, bounds, and other properties provided by the geocoder.

• input$<mapId>_geosearch_dragend Updated when the marker placed by the geosearch control is dragged to a new location (from the geosearch/marker/dragend event). Returns the same structure as above.

Both values are NULL if no result is available.
