PageTurn + Flutter WebView #9

Hi guys. I'm trying to use your plugin with Flutter WebView to render an epub file. The problem is that it seems that the PageTurn plugin doesn't work as expected when using Flutter WebView. All the pages are blank when using them together. Below the example main.dart I'm running:

import 'dart:convert';

import 'package:flutter/material.dart';
import 'package:page_turn/page_turn.dart';
import 'package:webview_flutter/webview_flutter.dart';

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

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
        visualDensity: VisualDensity.adaptivePlatformDensity,
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key}) : super(key: key);

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

class _MyHomePageState extends State<MyHomePage> {

  final _controller = GlobalKey<PageTurnState>();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: PageTurn(
        key: _controller,
        backgroundColor: Colors.white,
        showDragCutoff: false,
        lastPage: Container(child: Center(child: Text('Last Page!'))),
        children: <Widget>[
          for (var i = 0; i < 20; i++) WebViewWidget(),
        ],
      ),
      floatingActionButton: FloatingActionButton(
        child: Icon(Icons.search),
        onPressed: () {
          _controller.currentState.goToPage(2);
        },
      ),
    );
  }
}

class WebViewWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final htmlExample = "<!DOCTYPE html><html><body><h1>My First Heading</h1><p>My first paragraph.</p></body></html>";
    return WebView(
        initialUrl: Uri.dataFromString(
              htmlExample,
              mimeType: 'text/html',
              encoding: Encoding.getByName('utf-8')
            ).toString(),
        javascriptMode: JavascriptMode.unrestricted,
        initialMediaPlaybackPolicy: AutoMediaPlaybackPolicy.always_allow,
      );
  }
}

And the pubspec.yaml:
