How to highlight/toggle the image color?

[TheCodeCache]

Here is an input image -

I need to change this to below format -

Apologies for the tiny images.

If we observe the difference b/w the above two images, structure wise they both are same, it's just that their colors are toggled especially the center part of the image, which is white in the first image whereas it toggled black in the second.

How to switch/toggle color of a given image?
Is there any attribute on some flet image control or something similar, which highlights the image or achieve the above effect,?

Kindly advice!

You can try ShaderMask control to see if it suites your needs.
