About this widget

This component is an alternative to <Marker />. In some cases, you may want to have the full control of the marker rendering. You can provide any React components to design your custom marker.

The component currently doesn’t support options updates. Once the component is rendered, changing the props won’t update the marker options. You have to unmount then mount the widget back.
