String text

Gets or sets the text in the text box.

Implementation

String get text {
  if (_helper.isLoadedField) {
    IPdfPrimitive? str;
    final IPdfPrimitive? referenceHolder =
        _helper.dictionary![PdfDictionaryProperties.v];
    if (referenceHolder != null && referenceHolder is PdfReferenceHolder) {

        stream.decompress();
        final List<int> bytes = stream.dataStream!;
        final String data = utf8.decode(bytes);
        str = PdfString(data);
      } else if (textObject is PdfString) {

    }
    _text = str != null && str is PdfString ? str.value : '';
    return _text!;
  }
