I want to customize the Directions widget in order to be suitable for my application.
However, I do not know how to show a Directions widget without signing in to resources in http://www.arcgis.com.
Is this possible to do?
Flex is asking for an ArcGIS login because the default Network Route Service requires an organizational account which uses credits. Make your own Network Route Service and use that in combination with the free ArcGIS Online World Geocoding Service.
