Here are my codes:

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

class PDFViewerContainer extends StatefulWidget {


  const PDFViewerContainer({
    Key? key,
  }) : super(key: key);

  @override
  State<StatefulWidget> createState() {
    return PDFViewerContainerState();
  }
}

class PDFViewerContainerState extends State<PDFViewerContainer>  {
  late PDFDocument document;
  bool isLoading = true;
  String url = "https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf";

  @override
  void initState() {
    Future.delayed(Duration.zero,() async {
      document = await PDFDocument.fromURL(url);
      setState(() {
        isLoading = false;
      });
    });
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    if (isLoading){
      return CircularProgressIndicator();
    } else {
      return PDFViewer(document: document,);
    }
  }
}
