Text Selection not working in Webview when showing in pageview

[uc-ach]

When I am showing webview in Pageview builder, text selection doesn't work in Webview

Below is my code to reproduce issue, I am testing it on android device, having android 10 OS

my main.dart
`
import 'dart:io';
import 'package:flutter/material.dart';
import 'package:flutter/widgets.dart';
import 'package:preload_page_view/preload_page_view.dart';
import 'package:webview_flutter/webview_flutter.dart';
import 'package:webview_test/page.dart';
void main() {
runApp(MyApp());
}

class MyApp extends StatelessWidget {
    @override
    Widget build(BuildContext context) {
        return MaterialApp(
        title: 'PreloadPageView Demo',
        home: PreloadPageViewDemo(),
    );
}
}

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

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

class _PreloadPageViewState extends State {

@override
void initState() {
super.initState();
if (Platform.isAndroid) WebView.platform = SurfaceAndroidWebView();
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text("PreloadPageView Demo"),
),
body: Container(
child: PreloadPageView.builder(
preloadPagesCount: 5,
itemBuilder: (BuildContext context, int position) => DemoPage(position),
controller: PreloadPageController(initialPage: 1),
onPageChanged: (int position) {
print('page changed. current: $position');
},
)));
}
}`

my page.dart

`import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';
import 'dart:io';
class DemoPage extends StatefulWidget {
DemoPage(this.index);
final int index;

@OverRide
_DemoPageState createState() => _DemoPageState();
}

class _DemoPageState extends State {
@OverRide
void initState() {
super.initState();
if (Platform.isAndroid) WebView.platform = SurfaceAndroidWebView();
}

@OverRide
Widget build(BuildContext context) {
print('Page loaded: ${widget.index}}');

return Center(
child: WebView(
initialUrl: 'https://flutter.dev',
javascriptMode: JavascriptMode.unrestricted,
//onWebViewCreated: (controller) => _controller = controller,
),
);
}
}`

Please guide me if I am doing anything wrong
