Seeing the following unminified error:

Has this been fixed with tip of trunk Flutter? If not then we need to file a bug there.

It's hard to verify if this is still broken as we have another blocking issue on Chrome Canary: dart-lang/webdev#1087

[yjbanov]

I'm unable to reproduce in Chrome 86.0.4239.0. Can you please provide your chrome://version info?

[jpohhhh]

fwiw I'm on 86.0.4240.11 and seeing this

[harryterkelsen]

I filed an issue with dart2js to fix this in the compiler: dart-lang/sdk#43373

In the meantime I am landing a fix to the engine.

[yjbanov]

I think we can close this now?

[grouma]

I'm seeing this with the latest DevTools version pulled into package:dwds / package:webdev. (version 0.9.3+4)

@hterkelsen did your fix land?

This shouldn't be an issue anymore @grouma can you confirm if you still see this issue?
