Webview 설치를 위해 터미널에서 실행 및 pubspec.yaml에 추가된 것은 확인 했습니다.
강의 내용 중 android -> app-> build.gradle 에서 버전을 19로 수정하라고 해서 수정도 했습니다.
그런데 이상하게 build.gradle에서 error1개가 발생하구요 (라인 11, GradleException 에 빨간 줄(G 대문자 밑에요)이 생기고 quick fix도 업습니다.
그리고 mail.dart에서 2개의 error가 발생 합니다.
새로 추가한 widget (line 194 ~ line 207) 에서 발생된 에러는 quick fix로 수정할 수 있다고 하시는데 저한태는 그 옵션이 나타나지 않습니다.
