Coloring of the dotted selection line

[hartmannj]

Is there a way to set the color of the dotted selection line?
E.g. seen here: https://google.github.io/charts/flutter/example/interactions/selection_callback_example

Currently to change the color you would have to extend an existing style (MaterialStyle) or create your own. This is then applied to StyleFactory.style which affects all charts in your application.
