addMarkerPoint method

Future<void> addMarkerPoint(String markerId, String markerImage, List<Map<String, dynamic>> data, { double scale = 15, Map<String, dynamic> properties = const {"icon-opacity" : 1.0, "icon-size" : 1.0, "icon-anchor" : "center", "icon-offset" : [0.5, 0.5], 'icon-allow-overlap' : true, 'icon-ignore-placement' : true}, })

Adds a marker marker to the map and animates it between points.

• markerId: A unique identifier for the marker.
• markerImage: The path to the image file to be used as the marker icon.
• data: A list of position and rotation data for the marker animation {position: double, double, rotation: double}[].
• properties: (Optional) Custom properties for marker style.
• scale: (optional) A scale factor for the image.
