Hi,

I tried this package to download the pdf file in flutter web application using the below code and its working fine if i run this web application in localhost.

  final pdfData =
      await _generatePdf(eventdata, eventAttendeeEntry, typeOfReceipt);
  await Printing.layoutPdf(onLayout: (format) => pdfData);

  MimeType type = MimeType.PDF;
  String path = await FileSaver.instance.saveFile(
      'print_receipt_${eventAttendeeEntry.eventAttendeeEntryId}_${eventAttendeeEntry.eventAttendeeEntryPrintReceiptId}',
      pdfData,
      "pdf",
      mimeType: type);
  print('path = $path');

But if i deploy in server (firebase hosting) and then if i try then i get the below error. any idea? anything blocking in server?

oh sorry forgot to update this i did find a solution to this the code i used came cakked cross_file, link: https://pub.dev/packages/cross_file
Should note currently does not work on safari
The code is used is here:

      String fileName =
          '${event.invoice.projectNumber}-${event.invoice.invoiceNumber} Invoice.pdf';
      Uint8List fileData = await pdf.save();
      const String mimeType = 'application/pdf';
      final XFile pdfFile =
          XFile.fromData(fileData, mimeType: mimeType, name: fileName);
      await pdfFile.saveTo(fileName);

Hi @ranvirsahota, please test the latest updates and let me know

I'm receiving this error as well. But why does saveFile() return an error string instead of throwing an exception???
