The application crashes when I try to load a pdf file from assets (Android)

Al-Krause-ex commented 2 years ago

When I load a pdf file from assets, my application crashes. The PDF file is 2 MB.

The code: import 'package:advance_pdf_viewer/advance_pdf_viewer.dart'; import 'package:flutter/material.dart';

class PdfPage extends StatefulWidget { const PdfPage({Key? key}) : super(key: key);

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

class _PdfPageState extends State<PdfPage> { PDFDocument? doc; var isLoading = false;

@override void initState() { isLoading = true; loadDoc(); super.initState(); }

Future loadDoc() async { doc = await PDFDocument.fromAsset('assets/pdfs/screen.pdf'); setState(() { isLoading = false; }); } @override Widget build(BuildContext context) { return Scaffold( body: Center( child: isLoading ? const CircularProgressIndicator() : PDFViewer(document: doc!), )); } }

Mistake:
