@sigmundch is this relevant for the feature? If so, who would be the person to tackle this?

On the VM side we implemented the ability to display this attribute for a class here
https://dart-review.googlesource.com/c/sdk/+/285360
The VM service API was modified for this and I presume the dwds would have to be changed to provide the same information.

Thanks for reaching out @itsjustkevin - @annagrin is the main contact here.

@annagrin for my understanding, are these features part of the sdk or in a package?

[sigmundch]

Most of it lives in the dwds package, which is outside the SDK. That said, now that devtools is linked through DEPS and released with the sdk, I'm not sure whether that adds some constraints.

@annagrin - let us know to make sure we properly track whether the SDK hash can be selected prior to the support being completely landed or not. If this is not blocking, we could potentially move it to the next milestone, post the beta cutoff

[itsjustkevin]

Friendly ping.
