    bug plugin not working

    hi, i'm using this plugin and out of nowhere the plugin stopped working and gives this error:

    /opt/flutter/.pub-cache/hosted/pub.dartlang.org/pdf_viewer_jk-2.1.2/lib/src/document.dart:75:14: Error: The class 'File' is abstract and can't be instantiated. file = File("${dir.path}/file.pdf"); ^^^^ /opt/flutter/.pub-cache/hosted/pub.dartlang.org/pdf_viewer_jk-2.1.2/lib/src/document.dart:83:26: Error: Non-nullable variable 'file' must be assigned before it can be used. document._filePath = file.path; ^^^^ /opt/flutter/.pub-cache/hosted/pub.dartlang.org/pdf_viewer_jk-2.1.2/lib/src/document.dart:86:24: Error: Non-nullable variable 'file' must be assigned before it can be used. {'filePath': file.path, 'clearCacheDir': clearPreviewCache}); ^^^^

    edit: I also tested with the code that is in the github repository and gives the same problem

    @jawadsahil Because every version of flutter_test from sdk depends on async 2.6.1 and pdf_viewer_jk >=2.1.3 depends on async ^2.7.0, flutter_test from sdk is incompatible with pdf_viewer_jk >=2.1.3.

  • App crashes when navigating rapidly between pages using the BottomBar navigation buttons

    App crashes when navigating rapidly between pages using the BottomBar navigation buttons

    The app crashes when I navigate rapidly using the BottomBar navigation buttons. It does not happen while scrolling between pages. Also, sometimes the first page of the PDF is rendered as a rectangular placeholder image. Here is my code:

    class PdfView extends StatefulWidget {
  final String? pdfUrl;

  PdfView({Key? key, this.pdfUrl}) : super(key: key);

  @override
  _PdfViewState createState() => _PdfViewState();
}

class _PdfViewState extends State<PdfView> {
  bool _isLoading = true;

  PDFDocument? document;

  String title = "Loading";

  @override
  void initState() {
    super.initState();
    loadDocument();
  }

  Future<void> loadDocument() async {
    setState(() {
      _isLoading = true;
      title = "Loading";
    });
    document = await PDFDocument.fromURL(widget.pdfUrl!);
    setState(() {
      _isLoading = false;
    });
  }

  @override
  Widget build(BuildContext context) {
    return SafeArea(
      child: Scaffold(
        body: _isLoading
            ? Center(
                child: CircularProgressIndicator(

  • XMLHttpRequest error on fetching pdf from url

    XMLHttpRequest error on fetching pdf from url

    I have a functional android app in which I fetch pdf from url and display the fetched pdf in app, now I am trying to make the same work for web. I have put the code to fetch the pdf from url in try catch like this:

    if (kIsWeb) launch(pdfBillUrl);  
try {
      PDFDocument pdfDocument = await PDFDocument.fromURL(pdfBillUrl);
      ...
    } catch (error) {
      showDialog(
        context: context,
        builder: (context) {
          return AlertDialog(
            content: Text(error.toString()),
            actions: <Widget>[
              TextButton(
                child: const Text('OK'),
                onPressed: () => Navigator.of(context).pop(),
              )
            ],
          );
        },
      );
    }

    I am able to successfully open the pdf in chrome by using the url_launcher package and using it before try block and it works but the catch block is still triggered regardless.

    So I am displaying the error text and it says XMLHttpRequest error, in Chrome console, I can see

    Access to XMLHttpRequest at <pdf_url> from origin 'http://localhost:49306' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
