I cannot repro this with current beta:

$ flutter --version

$ dart run ffigen --config ffigen.yaml

$ flutter analyze

No issues found! (ran in 3.2s)

Is there some repro step I'm missing @domesticmouse ?

Ahh, yep. Switch to beta branch first. The primary difference is that I've bumped the minimum Dart version to 3.0.0-0 which turns on Dart 3 semantics. The PR to land this branch to main is #1746

If you change your lower constraint, then you are selecting a new language version (3.0), which by design is considered opting into breaking changes. So it's not really "broken on Flutter 3.10"; it needs to be "upgraded to support the Dart 3 language version"

Updating ffigen seems to fix it:

dev_dependencies:
  ffigen: ^8.0.0-dev.3

I'm now determining when that will be published as a stable version.

ffigen 8.0.0 is out: https://pub.dev/packages/ffigen/versions/8.0.0
