Consume scroll notification

Enable to nest mulitple ScrollShadow without the inner one interfering with the outer one

Hi @pixelshot91, I tried to reproduce your scenario of a ScrollShadow inside another ScrollShadow. However the behavior with and without your change for me is the same. Could you tell me which differences you found?
Thank you

I made two video showcasing the bug fix.
before_fix.webm
In this video, scrolling up and down works as expected, but when I scroll in the inner ScrollShadow, I have two huge shadows left and right, but there should not be. There should just be the little shadow left and right for each row.

after_fix.webm
In this video, evrything works as expected

The code used to create the video is available here:

The test is not mergeable yet. I need to add some 'expect' to check the position of the big shadow

[RichiB20]

Sorry, I tried the two scroll shadow in the same direction and I did't see any problem.
You're right, when you finish the test I will accept your PR.
Thank you for your work

I added the test and a 'flutter test' step in the workflow
