React Native MapView rotate map with camera heading

I am trying to rotate a map in React Native's <MapView> but haven't been able to find a description on how to rotate a map according to the heading of the camera. The tutorial states:

When this property is set to true and a valid camera is associated with the map, the camera’s heading angle is used to rotate the plane of the map around its center point.

So I came as far as:

<MapView          style={styles.map}          onRegionChange={this._onRegionChange}          onRegionChangeComplete={this._onRegionChangeComplete}          region={this.state.mapRegion}          annotations={this.state.annotations}          rotateEnabled={true}

But there is no explanation on how a camera is associated with the map.

Can anyone help with this issue please?
