PdfCompositeField class Null safety

Represents class which can concatenate multiple automatic fields into single string.

//Create a new pdf document
PdfDocument document = PdfDocument();
//Add the pages to the document
for (int i = 1; i <= 5; i++) {
  document.pages.add().graphics.drawString(
      'page$i', PdfStandardFont(PdfFontFamily.timesRoman, 11),
      bounds: Rect.fromLTWH(250, 0, 615, 100));
}
//Create the header with specific bounds
PdfPageTemplateElement header = PdfPageTemplateElement(
    Rect.fromLTWH(0, 0, document.pages[0].getClientSize().width, 300));
//Create the date and time field
PdfDateTimeField dateAndTimeField = PdfDateTimeField(
    font: PdfStandardFont(PdfFontFamily.timesRoman, 19),
    brush: PdfSolidBrush(PdfColor(0, 0, 0)));
//Create the composite field with date field
PdfCompositeField compositefields = PdfCompositeField(
    font: PdfStandardFont(PdfFontFamily.timesRoman, 19),
    brush: PdfSolidBrush(PdfColor(0, 0, 0)),
     text: '{0}       Header',
    fields: <PdfAutomaticField>[dateAndTimeField]);
//Add composite field in header
compositefields.draw(header.graphics,
    Offset(0, 50 - PdfStandardFont(PdfFontFamily.timesRoman, 11).height));
//Add the header at top of the document
document.template.top = header;
//Save the document.
List<int> bytes = document.save();
//Dispose the document.
document.dispose();
