CachedNetworkMarker class

The generator of custom marker. To show the custom marker on Google map for flutter, you have to pass the bitmap to BitmapDescriptor. This class will generate the custom marker with specified image url, and returns the bitmap. You can only use circleAvatar for now, but maybe more shapes will be added in the future. All marker bitmaps will be cached on user local for a month.

Your image will be resized automatically with original aspect ratio. The size of image will be decided with params for each generators.
