@Nullable
T getMessagePrototype()
```
    An instance of the expected message type, typically used as a schema and helper for producing other message instances. The null value may be a special value for the marshaller (like the equivalent of Void), so it is a valid return value. null does not mean "unsupported" or "unknown".
    It is generally expected this would return the same instance each invocation, but it is not a requirement.
