Changing the glow colour of PolylineGlowMaterialProperty

is there a way to access / change the Glow Colour of the PolylineGlowMaterialProperty?
It seems by default it is always white?

The PolylineGlowMaterialProperty does take a color, see:

Thanks for the answer.
However, I was looking for the glow color not the line-color.
I looked within the source but the glow colour ( the white ) is not set there explicitly.

Looks like this isn’t supported. If you’d like to add support for this we’d be happy to review a pull request! See the contributing guide here:
