I have a pdf_screen.dart file that will show a PDF directly when opened, does anyone can explain me how to use the functions of this library called flutter pdf viewer just to show my pdf?

Flutter PDF Viewer Library Example

 class _PdfScreenState extends State<PdfScreen> 

 final DocumentSnapshot document;
 String path;
 var dir;

 _PdfScreenState(this.document);


 @override
 void initState() 
 super.initState();
 getPdf();
 

 Future<void> getPdf() async 
 try 
 dir = await getApplicationDocumentsDirectory();
 setState(() 
 path = "$dir.path/$document["title"].pdf";
 );
 catch (e) 
 print(e);
 
 


 @override
 Widget build(BuildContext context) 

 if (path == null) 


 print("loading");
 return Container(
 color: Colors.white,
 child: Center(
 child: CircularProgressIndicator(backgroundColor: Colors.blueAccent,
 ),
 ),
 );
 else 

 return Container(
 child: ??; // I need to show my PDF here, I need to pass the path 
 // variable but PdfViewer is a function and it doesn't 
 // return a widget, how to implement?

As the readme says, this library launches a new intent, so it replaces your Flutter app in the stack until you use the back button. The example is clear how to achieve this.

However, as the readme continues, a proof-of-concept is available allowing you to render the PDF inside your Flutter app. Check out the branch from github to explore more.

A proof of concept for inline PDFs is available at the inline branch.
