flutter-maplibre-gl-example's Issues

Black screen error while the device offline

Hello,

I'd like to use the app while the device offline but I got black screen. The logs are bellow.

The modified code is bellow;

  bool _tilesLoaded = false;

  _copyTilesIntoPlace() async {
    try {
      await installOfflineMapTiles("assets/cache.db");
      print("-----------------  installOfflineMapTiles worked");
    } catch (err) {
      print(err);
    }
    setState(() {
      this._tilesLoaded = true;
    });
    print("_tilesLoaded--->" + _tilesLoaded.toString());
  }

  @override
  void initState() {
    _copyTilesIntoPlace();
    super.initState();
  }

When I run the app twice, cache.db loaded successfully.

I don't know how to load it properly.
