[syncfusion_flutter_pdfviewer] Error opening a PDF document - Invalid cross reference table

[saurabhDetharia]

Bug description

While loading some PDF documents in Flutter using SfPdfViewer.file returns an error. I have attached some PDFs for the reference.
computer_networks.pdf
sample.pdf

I also tried to load using the same file from the network source and it is having the same issue. Here is the source URL for the pdf I have used.

I have also referred here forum, but could not find the way to implement the below mentioned snippet (as suggested in the forum) in the SfPdfViewer. Is there any way to either resolve the exception or load such PDF files?

// Open an existing corrupted document from disk.
PdfLoadedDocument loadedDocument = new PdfLoadedDocument("Input.pdf", true);

Steps to reproduce

1. Create a new flutter web application
   flutter create syncfusion_pdfviewer_poc
2. Add syncfusion_flutter_pdfviewer package
   flutter pub add syncfusion_flutter_pdfviewer
3. Add SfPdfViewer widget to load the PDF.
4. Run the application.

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override

      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: SfPdfViewer.network(
