Detailed Description

A MessageCodec using unencoded binary messages, represented as ByteBuffers.

This codec is guaranteed to be compatible with the corresponding BinaryCodec on the Dart side. These parts of the Flutter SDK are evolved synchronously.

On the Dart side, messages are represented using ByteData.
