Flutter Solve: 'Offset is outside the bounds of the DataView' error only on Firebase Hosti-CodePudding

Code saving file:

   on<GeneratePDFFromInvoice>((event, emit) async {
      final aspHeaderLogo =
          await rootBundle.loadString('assets/images/asp_logo.svg');
      final aspFooterSlogan =
          await rootBundle.loadString('assets/images/asp_slogan.svg');
      final fontBold = Font.ttf(
          await rootBundle.load('fonts/Mulish/static/Mulish-Regular.ttf'));
      final regFont = Font.ttf(
          await rootBundle.load('fonts/Mulish/static/Mulish-Bold.ttf'));

      final pw.Document pdf =
          pw.Document(theme: PDFTheme(fontBold, regFont).themeData());

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

Error from browser console is:

Uncaught RangeError: Offset is outside the bounds of the DataView

The error occurs regardless of which browser I am on, but only happens when I deploy Firebase. There is no error on localhosting. The error doesn't seem to happen when I don't load a font into the PDF. Also using pdf_package link below. https://pub.dev/packages/pdf

CodePudding user response：

await rootBundle.load('assets/fonts/Mulish/static/Mulish-Bold.ttf'));

Simple type was the issue. missing 'assets' directory reference. Thanks to @Greg Fenton
