代碼保存檔案：
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);
});
來自瀏覽器控制臺的錯誤是：
Uncaught RangeError: Offset is outside the bounds of the DataView

無論我使用哪種瀏覽器都會發生錯誤，但僅在我部署 Firebase 時才會發生。本地主機沒有錯誤。當我沒有將字體加載到 PDF 中時，該錯誤似乎不會發生。也使用下面的 pdf_package 鏈接。 https://pub.dev/packages/pdf
uj5u.com熱心網友回復：
等待 rootBundle.load('assets/fonts/Mulish/static/Mulish-Bold.ttf'));
簡單型別是問題所在。缺少“資產”目錄參考。感謝@Greg Fenton
