If you do not use dart:ffi you may stop reading now.

We're making a breaking change in dart_api.h to disallow invoking Dart_NewWeakPersistentHandle and Dart_NewFinalizableHandle with Pointer and subtypes of Struct.

If you are using the dart_api in this way, please let us know your use cases by replying in the breaking change issue.
