Hi @Shark01. I'm getting this error every time I try to pass polylines from either googleMapPolyline.getCoordinatesWithLocation() or googleMapPolyline.getPolylineCoordinatesWithAddress() to GoogleMap widget. And above all, I'm getting null from googleMapPolyline.getCoordinatesWithLocation() which refers to this same issue #2.

Any help would be much appreciated. Thanks

This is my flutter doctor by the way,

Fixed the issue. It was my code, I wasn’t waiting to get the coordinates first before pass it to GoogleMap()

Hello @gadishimwe I'm glad that you fixed your issue by yourself. And I want you to inform that I have discontinued maintaining this package. So use it at your own risk. If you need to add features, please feel free to fork the repository and use it.
