BreakingUpgrade verdict

5 breaking changes.

In plain terms
  • If your config uses `assetId` for ffi-native, you must rename it to `asset-id`.
  • Objective-C block parameters and returns now use a generic Dart type, and the old generated wrapper class is no longer constructible.
  • You must enable Automatic Reference Counting for the generated Objective-C code, or it will not compile.
  • Struct fields that are enums now get an extra typed Dart enum member, unless you configure enums as integers.
