Based on the provided code example, we found that the PDF file was being saved without an extension, which was causing the reported issue. We suggest you add the proper extension when writing files. You can refer to the following code example for further details.

  Future<void> _createPdf() async {

    PdfDocument pdfdocumento = PdfDocument();

    final page = pdfdocumento.pages.add();



        'Impressão Matricular', PdfStandardFont(PdfFontFamily.helvetica, 35));


    List<int> bytes = await pdfdocumento.save();


    pdfSaver(bytes, 'matricula_data.pdf');



  Future<void> pdfSaver(List<int> bytes, String fileName) async {

    Directory path =

        await getApplicationDocumentsDirectory(); // function for see directory if android or ios

    String outputPath = path.path;

    final file = File('$outputPath/$fileName');

    await file.writeAsBytes(bytes, flush: true);
