Using image/svg icons in GoogleMaps plugin

Has anyone tried using SVG icons with the GoogleMaps plugin on iOS (the only one I’ve tried so far)? I get a threading error “GMSThreadException’, reason: 'The API method must be called from the main thread” when I set the icon: property for a Marker to something similar to “data:image/svg+xml;base64,xxxx” – the behavior is the same whether I do addMarker or addMarkerSync. I’m also doing this inside the map ready event.

Just curious if anyone has been able to get base64 encoded SVG icons to work with the GoogleMaps plugin.

svg is not supported.
