Issue with adding a symbol

I mentioned this issue at #316.

How to properly add a symbol?

Map Widget

MapBoxGL.MapboxMap(
                  onMapCreated: _onMapCreated,
                  onMapClick: (p, l) {
                    _addSymbol(l, asset_path_bnb + 'add.png');
                  },
                  trackCameraPosition: true,
                  myLocationEnabled: false,
                  tiltGesturesEnabled: false,
                  initialCameraPosition: MapBoxGL.CameraPosition(
                      target: MapBoxGL.LatLng(
                          BaseSharedPref.sharedPreferences
                              .getDouble('latitude'),
                          BaseSharedPref.sharedPreferences
                              .getDouble('longitude')),
                      zoom: 15),
                ),

Initializing the controller

  void _onMapCreated(MapboxMapController controller) {
    this.controller = controller;
  }

Adding a symbol

  void _addSymbol(MapBoxGL.LatLng latlng, String iconImage) {
    print('Add');
    controller.addSymbol(
      SymbolOptions(
        geometry: latlng,
        iconImage: iconImage,
      ),
    );
    setState(() {
      _symbolCount += 1;
    });
  }

Also, sometimes onMapClick function does not fire at all. What could be the issue?

The issue is resolved. The MapboxMapController wasn't properly disposed after a disposing the screen. But now it says Unhandled Exception: A MapboxMapController was used after being disposed. after doing

@override
void dispose() {
  controller.dispose();
  super.dispose();
}

Should I manually dispose the controller?

#315 should resolve this issue
