Google maps Integration

Hey Everyone, we had a specific set of requirement and that's related to the Maps. We are using Xamarin.Forms in this project.

1. Display Google maps on both Android and iOS.
2. Get current location of the device.
3. Provide the user with the ability to search new place i.e. A to B Route.
4. Show Polyline graph from A to B.
5. Also, show the current location as the user moves from A to B.

Can you please guide me what will the best approach for this.

Things I tried till the time
1. tried to integrate Google API maps using WebView, no success I am not able to load the HTML code shared in the Example.
2. Second I am trying to follow the github example of maps custom renderer but in that example hardcoded LAT Long are listed. Not sure how I will be able to get the RouteCordinates for dynamic positions

Thanks
