[Flutter Web] PlatformException(error, InvalidPDFException: Invalid PDF structure., null, null)

[sherrylin728]

I used the following code, and it displays correctly on mobile, but I encounter the following error on the web app. Could you please help me identify the issue?

body:
      PdfViewer.openFile(
        widget.path!,
        viewerController: controller,
        onError: (err) => print(err),
        params: const PdfViewerParams(
          padding: 10,
          minScale: 1.0,
          // scrollDirection: Axis.horizontal,
        ),
      ),

Error message
PlatformException(error, InvalidPDFException: Invalid PDF structure., null, null)

observing a similar issue with Flutter web

does not work with PdfViewer.openAsset(...) or PdfViewer.openData(...)
also tried it with different version from 1.3.1 - 1.4.6, but never worked.

PlatformException(error, TypeError: Cannot read properties of undefined (reading 'getDocument'), null, null)

Basically, Web version uses different PDF engine from other platforms.
Do you test your PDF file with pdf.js Demo?

Any solution ? I am getting the same issue PlatformException(error, InvalidPDFException: Invalid PDF structure., null, null)

@RobertoGeek12
Basically, it means the PDF file is broken or somehow complex structure that pdf.js could not open due to some limitation or some bug.

So anyway, could you please firstly check whether it can be opened or not by pdf.js demo.

If the demo site can open it, it means the issue may be just a bug or a limitation of the pdf.js version used by pdfrx; the bug may be fixed by upgrading pdf.js used by pdfrx.
