flutter - Flutter- Mapbox 拖动标记并获得新位置

Question

目前我正在使用这个包mapbox_gl: ^0.12.0

如何调用拖动结束功能并获得新位置？

final String _fillPatternImage = “assets/custom-icon.png”;

void _onMapCreated(MapboxMapController controller) {

this.controller = controller;

//controller.dr
//controller.onSymbolTapped.add(_onSymbolTapped);

this.controller.addSymbol(
      SymbolOptions(
        iconSize: 3,
        draggable: true,
        geometry: LatLng(
          _locationData.latitude,
          _locationData.longitude,
        ),
        iconImage: _fillPatternImage,
),);}
