How to load an existing pdf and print using printing in flutter

Question

I've been been trying to print an existing pdf file which is in sd card. So i added printing package to my flutter project to print pdf files.

Printing package link

I checked their documentation and i can't find a way to load and print pdf.

Fyi, i can create a pdf from image, text or whaetever it is and pass it to the Printing function. That works as anticipated.

final pdf = Document();

pdf.addPage(Page(
      pageFormat: PdfPageFormat.a4,
      build: (Context context) {
        return Center(
          child: Text("Hello World"),
        );
      })
);

await Printing.layoutPdf(onLayout: (PdfPageFormat format) async => pdf.save());

Any help to load existing pdf and print would be appreciable

Thanks

I finally find a way to print pdf using printing plugin.

You can directly print pdf by giving the online pdf url

To do so, just use the following dart snippet

http.Response response = await http.get('http://www.africau.edu/images/default/sample.pdf');
var pdfData = response.bodyBytes;
await Printing.layoutPdf(onLayout: (PdfPageFormat format) async => pdfData);

Don't forget to import http plugin

import 'package:http/http.dart' as http;

Thanks everyone for the help
