감사합니다 ~! 중급까지 고고싱~

BottomNavigation(TabBarView, Tab)사용시 개념 및 추가 질문

main.dart<pre class="hljs"><code>import 'package:flutter/material.dart';
import 'package:webview/screen/home_screen.dart';

void main() {
 runApp(
 const MaterialApp(
 home: HomeScreen(),
 ),
 );
}</code></pre>home_screen.dart<pre class="hljs"><code>import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';

class HomeScreen extends StatelessWidget {
 WebViewController? controller;
 final homeUrl = 'https://parkjh7764.tistory.com';
 HomeScreen({super.key}); //controller 가 const가 아니기 때문에 const를 없애준다.

 @override
 Widget build(BuildContext context) {
 return Scaffold(
 appBar: AppBar(
 title: Text('HwanE Blog'),
 centerTitle: true,
 backgroundColor: Colors.amber,
 actions: [
 IconButton(
 onPressed: () {
 if (controller != null) {
 controller!.loadUrl(homeUrl);
 }
 },
 icon: Icon(Icons.home_filled)),
 ],
 ),
 body: WebView(
 onWebViewCreated: (WebViewController controller) {
 this.controller = controller; //받아온 컨트롤러를 변수에 넣어준다.
 },
 initialUrl: homeUrl,
 javascriptMode: JavascriptMode.unrestricted,
 ),
 );
 }
}</code></pre>

const  지우고 저장하니 에러가 뜨네요

npm 버전 낮추어 해결하였습니다
