You will use the route data obtained from the Google Maps Directions API, which includes an encoded polyline string representing the full route between two points. This data is essential for rendering accurate navigation paths on the map.

The next step is decoding the encoded polyline into a list of latitude and longitude coordinates. After decoding, you will use Flutter’s Google Maps integration to draw the route on the map using a Polyline layer.
