PlatformException opening normal PDF

[enricobenedos]

Describe the bug
Unable to show/open a simple PDF, common PDF readers simply open it.

To Reproduce
Steps to reproduce the behavior:

import 'package:flutter/material.dart';
import 'package:pdfx/pdfx.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});
  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  late PdfController _pdfController;

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

    _pdfController = PdfController(
      document: PdfDocument.openAsset('assets/20220520_1827_IT.pdf'),
    );
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: PdfView(controller: _pdfController),
    );
  }
}
