Flutter - How to control google map markers opacity

Question

I need to make some markers semi-transparent depending on position. Is there any way to control the marker opacity?

Answer 1

Use the alpha property

static final Marker defaultMarker = Marker(
  markerId: MarkerId("0"),
  position: LatLng(0.0, 0.0),
  icon: BitmapDescriptor.defaultMarker,
  alpha: 0.5)
