Dart(DartObject)

Special Dart objects. These can only be sent from Rust to Dart

FinalizableHandle(Arc<FinalizableHandle>)

Can only be send from Rust to Dart. On Dart side this will be a FinalizableHandle instance. When handle gets garbage collected, the finalizer closure that FinalizableHandle was created with will be invoked.

You can send single FinalizableHandle instance to Dart more than once and it will always result in the same Dart object.

If the FinalizableHandle has already finalized it will be received as null.
