const를 왜 없애줘야 하나요?ㅜㅜ

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

class HomeScreen extends StatelessWidget {
  WebViewController? controller;

  const HomeScreen({Key? key}) : super(key: key);
// 여기서 왜 const를 없애야 하나요?ㅜㅜ
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Colors.orange,
        title: Text('Code Factory'),
        centerTitle: true,
      ),
      body: WebView(
        onWebViewCreated: (WebViewController controller) {},
        initialUrl: 'https://blog.codefactory.ai',
        javascriptMode: JavascriptMode.unrestricted,
      ),
    );
  }
}
