IControl class

Interface for interactive controls added to the map. This is a specification for implementers to model: it is not an exported method or class.

Controls must implement onAdd and onRemove, and must own an element, which is often a div element. To use Mapbox GL JS's default control styling, add the mapboxgl-ctrl class to your control's node.

class HelloWorldControl implements IControl {
  DivElement _divElement;
  @override
  String getDefaultPosition() {
    return 'bottom-left';
  }

  @override
  HtmlElement onAdd(MapboxMap map) {
    _divElement = DivElement();
    _divElement.text = 'Hello World';
    return _divElement;
  }

  @override
  onRemove(MapboxMap map) {
    _divElement.remove();
  }
}
