Upload Flutter-Navigation app for IVI

Flutter Navigation app which Shows current location,
Route for destination, search for destination in search bar,
turn by turn navigation,duration and distance for destination.
Used Mapbox api and Flutter_map plugin and integrated with
KUKSA.VAL for current location.
Update UI ,Removed unused code and remove hard coded access token.
