PDF view widget constant rebuild during view

Question

I am using syncfusion PDFviewer in a simple app to display a PDF from a URL using flutter. When I check the performance tap it shows the widget constantly rebuilding even though the page is fully loaded and I'm not interacting with the emulator. I'm not sure if this is supposed to be happening, but I don't see this for any other screen. Also occurs when accessing a PDF in assets or local file. Does this need a callback or setstate to stop the refresh? I know the words, but not the techniques.

Below is my code:

import 'package:flutter/material.dart';
import 'package:syncfusion_flutter_pdfviewer/pdfviewer.dart';

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

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
 return MaterialApp(
  title: 'SF PDFViewer Test',
  theme: ThemeData(
    primarySwatch: Colors.blue,
  ),
  home: MyHomePage(),
 );}}

 class MyHomePage extends StatefulWidget {
 @override
 _MyHomePageState createState() => _MyHomePageState();}

 class _MyHomePageState extends State<MyHomePage> {
 @override
 Widget build(BuildContext context) {
 return Scaffold(
   appBar: AppBar(
     title: Text('SF PDF Viewer Example'),),
  body: Center(),
  floatingActionButton: FloatingActionButton(
    onPressed: () => Navigator.push(
        context, MaterialPageRoute(builder: (context) => PdfViewerApp())),
    tooltip: 'View PDF',
    child: Icon(Icons.document_scanner_rounded),
  ),);}}

 class PdfViewerApp extends StatelessWidget {
 const PdfViewerApp({Key? key}) : super(key: key);

@override
Widget build(BuildContext context) {
 return SafeArea(
   child: Scaffold(
     appBar: AppBar(
       title: Text('SF PDFViewer'),
    ),
    body:
      Container(
        child: 
   SfPdfViewer.network('http://www.pdf995.com/samples/pdf.pdf'),
      ),),);}}
