Hi Alberto Monteverdi, 

 

Greetings from syncfusion. 

 

We do not have direct support to print the PDF document, instead we can print the PDF document with the help of printing package. Kindly try the following code in your end and let us know whether it achieves your requirement. 

1. Import the following package in your main.dart.

import 'package:printing/printing.dart'; 

 

2. Add the following code to preview the generate PDF file. With the help of onDocumentLoaded callback, the PDF document can be passed to printing widget.

3.  import 'dart:typed_data'; 

4.  import 'package:flutter/material.dart'; 

5.  import 'package:syncfusion_flutter_pdfviewer/pdfviewer.dart'; 

6.  import 'package:printing/printing.dart'; 

7.  void main() {​​​​​​​​ 

8.    runApp(MaterialApp( 

9.      title: 'Syncfusion PDF Viewer Demo', 

10.     home: HomePage(), 

11.   )); 

12. }​​​​​​​​ 

13. /// Represents Homepage for Navigation 

14. class HomePage extends StatefulWidget {​​​​​​​​ 

15.   @override 

16.   _HomePage createState() => _HomePage(); 

17. }​​​​​​​​ 

18. class _HomePage extends State<HomePage> {​​​​​​​​ 

19.   final GlobalKey<SfPdfViewerState> _pdfViewerKey = GlobalKey(); 

20.   @override 

21.   Widget build(BuildContext context) {​​​​​​​​ 

22.     return Scaffold( 

23.       appBar: AppBar( 

24.         title: const Text('Syncfusion Flutter PDF Viewer'), 

25.         actions: <Widget>[ 

26.           IconButton( 

27.             icon: const Icon( 

28.               Icons.bookmark, 

29.               color: Colors.white, 

30.             ), 

31.             onPressed: () {​​​​​​​​ 

32.               _pdfViewerKey.currentState?.openBookmarkView(); 

33.             }​​​​​​​​, 

34.           ), 

35.         ], 

36.       ), 

37.       body: SfPdfViewer.asset( 

38.         'assets/sample.pdf', 

39.         key: _pdfViewerKey, 

40.         onDocumentLoaded: (PdfDocumentLoadedDetails details) async {​​​​​​​​ 

41.           final Uint8List bytes = Uint8List.fromList(details.document.save()); 

42.           await Navigator.push<dynamic>( 

43.               context, 

44.               MaterialPageRoute<dynamic>( 

45.                   builder: (BuildContext context) => SafeArea( 

46.                         child: PdfPreview( 

47.                           build: (PdfPageFormat format) => bytes, 

48.                         ), 

49.                       ))); 

50.         }​​​​​​​​, 

51.       ), 

52.     ); 

53.   }​​​​​​​​ 

54.    } 

 

Please let us know if you have any doubts.

Dilli babu.
