updated title - this seems like a crash in ListFactorySpecializer.transformListGenerateFactor.

Aside - it may be worth also looking into adding our typical crash wrapper to the transformers as well, so we can provide more context on the error location.

I think this is actually a bad cast in CFE code. Tentative fix: https://dart-review.googlesource.com/c/sdk/+/303420

when can we expect this to be released? it's a quite while now.

Update:
Still happens in Flutter 3.10.3 (Dart SDK build number 3.0.3), but only when building for web. Building for iOS seems to work fine.
