Android exception for addImage

[sqcsabbey]

In my onMapCreated callback, I'm running:

var name = "marker";
var assetPath = "assets/map/marker.png";
final ByteData bytes = await rootBundle.load(assetPath);
final Uint8List list = bytes.buffer.asUint8List();
return await _mapboxController.addImage(name, list);

... and got (the first time I've noticed this):

This works for me most of the time, but I'm having trouble on the first map load. I'm calling the code I included from the MapboxMap's onMapCreated callback. It looks like the error is due to the style being null, but I'm not setting my own style, so it should be a default one...

Is there anything else I could include that might point to the problem?

I moved my addImage calls to onStyleLoadedCallback and it's working.
