Implementation

String? get outputText {
  StringBuffer buf = StringBuffer();

  if (output != null) {
    for (final o in output!) {
      if (o is OutputMessage) {
        for (final content in o.content.whereType<OutputTextContent>()) {
          buf.write(content.text);
        }
      }
    }
  }
  if (buf.isEmpty) {
    return null;
  }
  return buf.toString();
}
