오류

선생님 덕분에 해결이 됐습니다. 정말 감사합니다.

그럼 라이브러리 버전간의 문제가 있었던 것 같네요.

일단 저랑 맞췄는데도 안 된다면 로그인 코드를 확인해 보셔야 할 듯 하네요. 로그인 버튼 눌렀을 때  _handleSignIn() 만 하시면 됩니다.

https://github.com/junsuk5/flutter_insta_clon/blob/master/lib/login_page.dart

그리고 rootPage도 확인해 보세요.

https://github.com/junsuk5/flutter_insta_clon/blob/master/lib/root_page.dart

혹시 버전에 문제가 있나 생각해서 모든 버전을 선생님하고 동일하게 했습니다.

그리고 main()도 선생님처럼 같은 코드를 짜고 firbase_core 라이브러리도 없애고 돌렸는데 에러같은건 안뜨는데 로그인 버튼을 누른 뒤 화면 전환이 안되는거 같습니다.

선생님 일단 제가 firebase_auth: ^0.18.0+1로 돌렸었는데요 선생님 말대로 버전을 낮춰서 pub get을 했는데 

Because firebase_auth >=0.10.0 <0.15.5 depends on firebase_core ^0.4.0 and instagram_clone depends on firebase_core ^0.5.0, firebase_auth >=0.10.0 <0.15.5 is forbidden.

So, because instagram_clone depends on firebase_auth ^0.14.0+5, version solving failed.

pub get failed (1; So, because instagram_clone depends on firebase_auth ^0.14.0+5, version solving failed.) 

이런 문구가 떠서 firebase_core 버전을 0.4.0으로 낮춰서 돌렸습니다. 그랬더니

이런 문제가 떴습니다.

이런 말이 뜹니다. 

에러메시지의 라인 번호에 해당하는 코드 확인이 안 되어 어느 부분이 문제인지 모르겠네요.

코드는 제 코드와 같기 때문에

라이브러리 버전을 제꺼와 동일하게 해도 같은 에러가 발생하는지 확인해 보시겠어요?

추가적으로 전체적인 에러를 다 보여드리면

코드부분은 선생님께서 올려주신 깃헙을 보고 다시 맞춰서 코드를 짰습니다.

에러메시지만 봤을 때 FirebaseUser 타입을 User 타입 변수에 대입하려고 해서 발생한 에러 같습니다.

에러가 발생한 부분의 코드를 보여주시면 좀 더 알려드릴 수 있을 것 같습니다.
