To reproduce, run the dartanalyzer on https://github.com/dart-lang/glob/blob/master/test/list_test.dart

@scheglov The only labels in the source are for named arguments. Any idea what might be causing this?

[kevmoo]

@isoos – which version of the SDK?

[scheglov]

I cannot reproduce it.
I suspect this might have been fixed in a73c8d0.

[bwilkerson]

I thought that might be the case.

@isoos Please let us know if you continue to see this after upgrading to the next dev or stable release.

[kevmoo]

@isoos I haven't seen this is my runs, either – and I'm on 1.24-latest-dev

[isoos]

FWIW it was in SDK 1.23.
