How to compare two images and highlight the difference in new image in flutter?

I am a flutter developer. My need is to compare two images and highlight the difference (between two images) in a new image in flutter?

Two images First image and Second image.

My requirement is to compare those images and highlight the difference region in another image Difference image. I am trying to achieve screenshot based UI testing in flutter and need to fail the test cases if there is any differences between two images.

Please find the below screenshots for reference.

Is there any package in flutter/dart to achieve the same output?

Thanks and regards,

Ashwin
