I can't reproduce it under macOS.

I can reproduce this. Looking into it now.

[jcollins-g]

This is a problem with inconsistent special object handling (at least). #1554

[chalin]

@jcollins-g - after downgrading dartdoc to version 0.20.0 I was able to generate the docs. I assume that we can use 0.20.0 for the next little while (in case you have more pressing issues to address)?

[jcollins-g]

0.20.0 is shortly going to stop working >dev-69.0. So this is pretty high on my list to get fixed.

[jcollins-g]

And strangely, despite fixing the problem I saw and testing to make sure that this exception didn't happen, after merging I see it again.

[jcollins-g]

Might be related to the SDK version -- I'm using 69.2 post merge and 69.0 is what I tested the fix against.

[jcollins-g]

Angular was broken with two problems -- one that I fixed in #1729, and this one. It looks like this issue only occurs when [dynamic] is part of a comment reference, and only with an updated version of the analyzer/SDK.
