java.lang.NullPointerException: null cannot be cast to non-null type kotlin.Boolean

[mbaka-bilal]

i followed all the setup instructions for android from the pub.dev page but when try to run the code it throws error:

//Code from pub.dev
final cityhall = WayPoint(name: "City Hall", latitude: 42.886448, longitude: -78.878372);
final downtown = WayPoint(name: "Downtown Buffalo", latitude: 42.8866177, longitude: -78.8814924);

var wayPoints = <WayPoint>[];
wayPoints.add(cityhall);
wayPoints.add(downtown);

This is the log

The isSilent property on the Waypoints must be there. For example:
WayPoint( name: "Destination", latitude: 13.159545, longitude: -61.224829, isSilent: false)

This is resolved in v0.1.9
