Ability to change rotation on ClusterItem

[cwsiteplan]

I do show labels on the map which should follow the camera bearing (map rotation). Similar to street names in GoogleMap - they rotate with the map.

by only exposing clusterItemContent we are not able to change the rotation of the Marker.

Applying the rotation on the composable content

clusterItemContent = {
            MyLabel(
                it.label,
                modifier = Modifier.rotate(rotation)
            )
        }

does not work as it then exceeds the bounds of the rendered marker - see below:

would be nice if someone can take a look at this

Hi @cwsiteplan . I think this could probably be solved using the function marker.rotation(float value), but there is no easy access to it. It would also require changes on android-maps-utils.

The DefaultClusterRenderer provides a function to be overridden, onClusterItemUpdated. This function receives a marker that could potentially be modified.

How to pass this all the way-up it is an open question. Custom Renderers can now be created, so an option could be to override it (similar to this sample in the android-maps-utils) and provide an option to rotate the marker. That could theoretically work, but we would also need to somehow keep the relationship about which markers get which rotation.
