Thanks for thinking about improving this!

For some reason it's not triggering, but CI is supposed to include a formatting check against these files with dart format. Running dart format will revert many of these changes. I'll work on fixing that check. (Edit: #11027)

What do you think about instead moving the docregion comments above the previous line (like child: ...)? It will end up showing some extra information, but I think that's okay considering the examples. We can remove those properties with other code excerpt functionality if needed as well.

No worries! I went ahead and moved the comments and added replacement instructions for the code excerpt tool. You can check out the commit 9346457 to see what I did.

As for the error, let me know if you hit it again and I'd be happy to fix it or work through a solution with you.

Thanks again for doing this!!
