# getValue method

String getValue()

Gets the value of the text field.

return Value of the text field. throws DocumentException An error has occurred during Document Library execution.

## Implementation

    String getValue() {
      Pointer<Char> pValue = nullptr;
      Pointer<Int> pValueSize = calloc.allocate(1);
      pValueSize[0] = -1;
      try {
        var err = documentSDK.id3DocumentTextField_GetValue(_pHandle.value, pValue, pValueSize);
        if (err == DocumentError.insufficientBuffer.value) {
          pValue = calloc.allocate(pValueSize.value);
          err = documentSDK.id3DocumentTextField_GetValue(_pHandle.value, pValue, pValueSize);
          if (err != DocumentError.success.value) {
            throw DocumentException(err);
          }
        }
        final vValue = utf8.decode(Uint8List.fromList(pValue.cast<Uint8>().asTypedList(pValueSize.value)));
        return vValue;
      } finally {
        calloc.free(pValue);
        calloc.free(pValueSize);
      }
    }
