BitmapDescriptor custom markers

[hsynksahin]

I've tryed to add a custom marker on the map. I can clearly say that some applications using something just like BitmapDescriptor.markerAnnotation but there is a custom black icon in the middle of it. Thoose apps written by swift I can say. But if there is a custom marker option, we can do the same too via flutter.

Why not add a constructor for marker that has parameters of hue, icon, size of icon (customizations for icon) etc.

Also there is a problem about BitmapDescriptor.fromAssetImage and byte version of it. That we can not change the size of the image we are using. After examined the package's code I've tryed this Bitmap to make scale work:

BitmapDescriptor.fromAssetImage(
      const ImageConfiguration(
        devicePixelRatio: 0.00001,
      ),
      'assets/images/logo/brand/black.png',
      mipmaps: false,
    ).then((bitmap) {
      _bitmap = bitmap;

      setState(() {});
    });

But there is no differance at all! that image is 230x230 pixels and its covering the half of the screen no mather what I do. I clearly need a scaling function or differant sizes of this asset for every single device pixel ratio...
