this might be just due to a missing strong mode dill, it might be fixed by the engine roll

jonahwilliams commented 4 years ago

The latest engine update did not resolve the situation

jonahwilliams commented 4 years ago

We need to produce both a weak and strong mode dill in the engine build, and conditionally switch based on the experiment.

Blocked on dart:_engine migration.

jonahwilliams commented 4 years ago

The dart_engine migration has landed, now waiting on https://github.com/flutter/engine/pull/19162 to land and roll

jonahwilliams commented 4 years ago

Fixed via https://github.com/flutter/engine/pull/19386
