Android: setStyleJSON not working after upgrading plugin version 2+

After upgrading the plugin from version 1.1.0 to 2.0.0, I have some issues when developing for Android.

I try to set a custom style json like this in the onMapCreated callback:

_onMapCreated(MapboxMap mapboxMap) async {
    this.mapboxMap = mapboxMap;

    final styleJson = await rootBundle.loadString("assets/map-styles/my_style.json");
    mapboxMap.style.setStyleJSON(styleJson);

    print("done");
}

I see the log message in the console, so the code is executed as expected without any error, but I still see the default Mapbox style on Android. It is working as expected on iOS and it was also working on Android using plugin version 1.1.0.

Futhermore, when adding a layer in the onStyleLoadedListener like this:

_onMapStyleLoaded(StyleLoadedEventData styleLoadedEventData) async {
    final linesData = await rootBundle.loadString('assets/map-data/lines.json');
    await mapboxMap?.style.addSource(GeoJsonSource(id: "source_lines", data: linesData));
    await mapboxMap?.style.addLayer(
        LineLayer(
            id: "layer_lines",
            sourceId: "source_lines"
        )
    );
}

I see the added layer, but I also see an exception on Android:

It is working as expected on iOS and it was also working on Android with plugin 1.1.0.

Full sample project:
flutter_mapbox.zip

Inizia eseguendo su Android l'esempio flutter_mapbox collegato e confrontando il comportamento tra le versioni del plugin 1.1.0 e 2.0.0. Esamina il percorso Android StyleController.addStyleSource identificato nello stack trace e i callback setStyleJSON/style-loaded. Il lavoro è completato quando viene visualizzato lo stile personalizzato e la source può essere aggiunta senza la duplicate-source exception.
