missing space before :

Done.

+ public:
+  Dart_Port Id() const { return raw_ptr()->send_port_->ptr()->id_; }

maybe

send_port()->ptr()->id_;

+
+  RawSendPort* send_port() const { return raw_ptr()->send_port_; }
+
+  RawInstance* handler() const { return raw_ptr()->handler_; }
+  void set_handler(const Instance& value);

where is set_handler implemented ?
maybe it should also be a const.
