Flutter RefreshIndicator not displaying in column

Time：04-14

I'm trying to implement RefreshIndicator in a webview , for that I wrap my web view in a column. Problem is RefreshIndicator not displaying in top. I have tried by wrap column into a singlechildscrollview then given physics: const AlwaysScrollableScrollPhysics(), but getting exception RenderBox was not laid out. How can I fix the issue ?

body:RefreshIndicator(
                    onRefresh: ()=>webViewController.reload(),
                    child: Column(
                    children: [
                     Expanded(
                       child: WebView(
                          javascriptMode: JavascriptMode.unrestricted,
                          userAgent: 'random',
                          initialUrl: 'https://stackoverflow.com/',

                          onWebViewCreated: (webViewController){
                            this.webViewController = webViewController;
                          },
                     ),
            ),
        ],
    ),
),

Update :

To implement RefreshIndicator I take the hight using JavaScript , my mail dart is like below

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


void main() {
    runApp(
        const MaterialApp(
            home: WebViewApp(),
        ),
    );
}

class WebViewApp extends StatefulWidget {
    
    const WebViewApp({Key? key}) : super(key: key);

    @override
    State<WebViewApp> createState() => _WebViewAppState();
}

class _WebViewAppState extends State<WebViewApp> {
    late WebViewController webViewController;
    double pageHeight = 100;

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

    @override
    Widget build(BuildContext context) {
        return WillPopScope(
        onWillPop: () async {
            if(await webViewController.canGoBack()){
                webViewController.goBack();
                
                return false;
            }else{
                return true;
            }
        },
        child: Scaffold(
                appBar: AppBar(
                    backgroundColor: const Color.fromRGBO(234, 53, 45, 1),

                    actions: [
                        IconButton(
                            onPressed: () async {
                                if(await webViewController.canGoBack()){
                                    webViewController.goBack();
                                }   
                            }, 
                            icon: const Icon(Icons.arrow_back),
                        ),
                        IconButton(
                            onPressed: ()=>webViewController.reload(), 
                            icon: const Icon(Icons.refresh)
                        )
                    ],

                    title: const Center(child: Text('GameClub')),
                ),

                body: RefreshIndicator(
                    onRefresh: ()=>webViewController.reload(),
                    child: SingleChildScrollView(
                        physics: const AlwaysScrollableScrollPhysics(),
                        child: Container(
                            height: pageHeight,
                            child: WebView(
                                javascriptMode: JavascriptMode.unrestricted,
                                userAgent: 'random',
                                initialUrl: 'https://stackoverflow.com/',
        
                                onWebViewCreated: (webViewController){
                                    this.webViewController = webViewController;
                                },
        
                                onPageFinished: (url) async{
                                    print(url);
                                    var result = await webViewController.runJavascriptReturningResult("document.body.scrollHeight");
                                    setState(() {
                                        pageHeight = double.parse(result);
                                    });
                                    print(pageHeight);
                                },
                                
                            ),
                        ),
                    ),
                ),
            ),
        );
    }
}

It's working fine in iOS also working fine in some android device, but in some device I'm getting below error and app is crashing.
