파이어스토어 필드가 없을 때 오류처리

[김윤호]

안녕하세요.
플러터랑 파이어스토어 데이터베이스를 연결하고, 데이터 베이스 값들을 불러온 뒤에
Text(documentSnapshot['1_테스트']), 라고 했을 때 documentSnapshot에 ['1_테스트']라는 값이 없으면
아래와 같은 오류가 발생합니다

이걸 해결하기 위해서 Text(documentSnapshot['1_테스트'] ?? '오류'),
로 처리로 해도 아래와 같은 오류가 나타납니다.
이걸 어떻게 해결해야 될까요?

doc.data().toString().contains('id') ? doc.get('id') : '' 식으로 삼항연산자 쓰라는거같습니다
