@jacob314 @gspencergoog Did you see this behavior on the latest flutter master channel? Or somewhere else?

Bump dart/language_model to 9fJQZ0TrnAGQKrEtuL3-AXbUfPzYxqpN_OBHr9P4hE4C

I still don't totally understand why there are two revisions of the package specified here, but an older model is currently being distributed with a newer version of analysis server. That's causing dart-lang/sdk#39079.

Yes, latest Flutter master:

Flutter 1.10.15-pre.253 • channel density • [email protected]:gspencergoog/flutter.git
Framework • revision 3cc69eacaf (3 minutes ago) • 2019-10-25 08:55:02 -0700
Engine • revision 8d6b74aee6
Tools • Dart 2.6.0 (build 2.6.0-dev.8.2 1bd6e20d76)

I've had it happen several more times, same stack trace.

Thanks! This will be fixed once flutter/engine@c272b18 is picked up in the next roll.
