The default value of the [`initialMarkersCount`](https://pub.dev/documentation/syncfusion_flutter_maps/latest/maps/MapLayer/initialMarkersCount.html) property is `null`.

|

You can add markers dynamically using the [`MapShapeLayerController.insertMarker`](https://pub.dev/documentation/syncfusion_flutter_maps/latest/maps/MapShapeLayerController/insertMarker.html) method. The [`markerBuilder`](https://pub.dev/documentation/syncfusion_flutter_maps/latest/maps/MapLayer/markerBuilder.html) will be called for the respective index once [`insertMarker`](https://pub.dev/documentation/syncfusion_flutter_maps/latest/maps/MapShapeLayerController/insertMarker.html) method is called. The [`controller`](https://pub.dev/documentation/syncfusion_flutter_maps/latest/maps/MapShapeLayer/controller.html) property of [`MapShapeLayer`](https://pub.dev/documentation/syncfusion_flutter_maps/latest/maps/MapShapeLayer-class.html) has to be set with the new instance of [`MapShapeLayerController`](https://pub.dev/documentation/syncfusion_flutter_maps/latest/maps/MapShapeLayerController-class.html).

## Updating the existing markers
|
||||
|
||||
You can update multiple markers at a same time by passing indices to the [`updateMarkers`](https://pub.dev/documentation/syncfusion_flutter_maps/latest/maps/MapShapeLayerController/updateMarkers.html) method in the [`MapShapeLayerController`](https://pub.dev/documentation/syncfusion_flutter_maps/latest/maps/MapShapeLayerController-class.html). The [`markerBuilder`](https://pub.dev/documentation/syncfusion_flutter_maps/latest/maps/MapLayer/markerBuilder.html) will be called again for the respective indices once [`updateMarkers`](https://pub.dev/documentation/syncfusion_flutter_maps/latest/maps/MapShapeLayerController/updateMarkers.html) method is called.
