Implementation

void dispose({required int sessionId}) {
  _validateId(sessionId, 'session id');
  final errorOut = calloc<_RitoOwnedBuffer>();
  try {
    final status = _dispose(sessionId, errorOut);
    if (status != 0) {
      throw _nativeError(status, errorOut);
    }
  } finally {
    _bufferFree(errorOut);
    calloc.free(errorOut);
  }
}
