title: UPDATE PDF preview content Flutter using printing Package?
body: <p>It is possible to UPDATE the content of PDF preview on Flutter using printing Package?</p>
  <p>I want to create a PDF preview using printing package for print a QR code and nothing else.</p>
  <p>I already created the PDF and show de QR from my String _data, but, when the app return back menu, and change the _data from TextField, also try to print again but the pdf created before keeps de last _data content, although in my debugging I confirmed the String _data content changes.</p>
  <p>My code is here in the stackOverFlow Spanish (sorry for that I'm newbie xd): <a href="https://es.stackoverflow.com/questions/498523/c%C3%B3mo-actualizar-la-vista-del-pdf-creado-con-printing-package-en-flutter-dart">https://es.stackoverflow.com/questions/498523/cómo-actualizar-la-vista-del-pdf-creado-con-printing-package-en-flutter-dart</a></p>
