How to load a pdf file from Application Directory in flutter? - pdf

Question

I am trying to load a PDF file from the application directory, I tried loading it from the url and it works and no I need to load the already downloaded PDF from the Application directory.
This is the package that I used to view PDF flutter_pdfview, while trying to load it from a url this works fine, now what I need is load an already downloaded pdf from the directory.
for loading file from directory i tried this:
var dir = await getApplicationDocumentsDirectory();
File file = File('${dir.path}/$pName.pdf');
bool fileExists = File(await '${dir.path}/$pName.pdf')
.existsSync();
if(fileExists)
{
urlPdfPath = file.toString();
print('url pdf path $urlPdfPath');
Navigator.push(context, MaterialPageRoute(builder: (context) {
return PdfViewer(
path: urlPdfPath,
product: pName,
);
}));
}
when i run this i got the exception
D/AndroidRuntime( 4565): Shutting down VM
E/AndroidRuntime( 4565): FATAL EXCEPTION: main
E/AndroidRuntime( 4565): java.lang.IllegalArgumentException: Unsupported value: java.io.FileNotFoundException: No such file or directory

In your Code:
Change - urlPdfPath = file.toString(); to urlPdfPath = file.path;
