JSon to Dart null safe사이트에서 conver to dart로 변경을 한 소스이면 에러가 나는것 같습니다.
&nbsp;
안드로이드 스튜디오에서 json to dart로 변경 후
photo_widget.dart에서 아래와 같이 변경 하니 에러가 나지 않습니다.
아래와 같이 하고 진행해도 괜찮을까요?
<pre style="background-color: #2b2b2b; color: #a9b7c6; font-family: 'Menlo',monospace; font-size: 9.8pt;">import 'package:flutter/material.dart'; import 'package:image_search/model/photo.dart'; class PhotoWidget extends StatelessWidget { final Photo photo; const PhotoWidget({ Key? key, required this.photo, }) : super(key: key); @override Widget build(BuildContext context) { return Container( decoration: BoxDecoration( borderRadius: const BorderRadius.all(Radius.circular(16.0)), image: DecorationImage( fit: BoxFit.cover, image: NetworkImage(photo.previewURL!), <-- 이렇게 변경 함 ), ), ); } }</pre>

앗.. 제실수가 맞습니다.
감사합니다.

StreamBuilder 부분 질문 드립니다.

위의 코드상에는 자세히 보이지는 않습니다만,
return Text('${snapshot.data}', style: TextStyle(fontSize: 30));
으로 되어 있습니다.

추가 질문 드립니다.
강의 소스중
<pre style="background-color: #2b2b2b; color: #a9b7c6; font-family: Menlo; font-size: 11.3pt;">Future<FirebaseUser> _hadleSignIn() async { GoogleSignInAccount googleUser = await _googleSignIn.signIn(); GoogleSignInAuthentication googleAuth = await googleUser.authentication; FirebaseUser user = await _auth.signInWithCredential(GoogleAuthProvider.getCredential(idToken: googleAuth.idToken, accessToken: googleAuth.accessToken)); return user; }</pre>
<pre style="background-color: #2b2b2b; color: #a9b7c6; font-family: Menlo; font-size: 11.3pt;">await _auth.signInWithCredential(GoogleAuthProvider.getCredential(idToken: googleAuth.idToken, accessToken: googleAuth.accessToken));</pre>
이부분에서 빨간줄이 생깁니다.

잘못된곳이 없지 싶은데요...

firebase 연동 후 빌드시 에러가 납니다.

감사합니다.
마지막에 알려주신 데로 수정하였더니 빌드에러가 나지 않아
