  - onMessage
```
@UiThread
void onMessage(@Nullable
               ByteBuffer message,
               @NonNull
               BinaryMessenger.BinaryReply reply)
```
    Handles the specified message.
    Handler implementations must reply to all incoming messages, by submitting a single reply message to the given BinaryMessenger.BinaryReply. Failure to do so will result in lingering Flutter reply handlers. The reply may be submitted asynchronously.
    Any uncaught exception thrown by this method will be caught by the messenger implementation and logged, and a null reply message will be sent back to Flutter.
    
    Parameters:
    
    message - the message ByteBuffer payload, possibly null.
    
    reply - A BinaryMessenger.BinaryReply used for submitting a reply back to Flutter.
