return The log message. throws BiosealException An error has occurred during Bioseal Library execution.

## Implementation

    String getMessage() {
      Pointer<Char> pMessage = nullptr;
      Pointer<Int> pMessageSize = calloc.allocate(1);
      pMessageSize[0] = -1;
      try {
        var err = biosealSDK.id3BiosealLogItem_GetMessage(_pHandle.value, pMessage, pMessageSize);
        if (err == BiosealError.insufficientBuffer.value) {
          pMessage = calloc.allocate(pMessageSize.value);
          err = biosealSDK.id3BiosealLogItem_GetMessage(_pHandle.value, pMessage, pMessageSize);
          if (err != BiosealError.success.value) {
            throw BiosealException(err);
          }
        }
        final vMessage = utf8.decode(Uint8List.fromList(pMessage.cast<Uint8>().asTypedList(pMessageSize.value)));
        return vMessage;
      } finally {
        calloc.free(pMessage);
        calloc.free(pMessageSize);
      }
    }
