Arrow become invisible if passing Colors.Grey as background color

Version 0.0.4

Since you allow to pass background color, it probably makes sense to allow customizing arrow colors, e.g. replace:

foregroundPainter: ArrowCustomPainter(Colors.grey),

with:

foregroundPainter: ArrowCustomPainter(arrowColor),

where arrowColor can be provided in a constructor.

I would like to second the idea of a configurable arrow color. In our app, all of the calls to action are of a particular background color and text/icon color. I'd like to make the arrow scroller adhere to that design. Any chance of implementation? Thanks!
