'Flutter - How can I let a user erase part of an image and make it transparent?

My goal is to let a user selected image (via image_picker) and then use an eraser type tool to modify that image and make it transparent. Any ideas on how I should go about this?

What you need to do is not really straight forward but you can try image package out. So many things can be done with it.
