Pet은 등록 시 사진이 없을 수 있는 객체이지 않나요?

만약 현재 Pet Entity 를 생성한다면 profileImage를 받지 않은 경우라면 Pet을 생성조차 못하는 상황으로 보입니다.

Kotlin 에서는 자바와 다르게 Null이 들어갈 수 있는 타입과, Null이 들어갈 수 없는 타입으로 나뉩니다.
String? 과 같은 타입으로 사용하면 Null이 들어갈 수 있는 String 이고 String 으로만 쓴다면 Null이 들어갈 수 없는 String 입니다.

Kotlin 에서는 왜 이것을 나누어 사용하는지 알아보면 좋을 것 같습니다~

Pet의 profileImage 와 동일하게 생성 시 memories 는 항상 그 값을 초기화 하도록 선언되어, 언제나 빈 리스트가 될 것 같은데 이 경우에는 Default 값을 사용해주는 것이 어떨까요?

컬럼 자체에서는 nullable = false 로 null이 들어갈 수 없는 상태로 선언 되었지만 해당 객체는 생성 시 null이 Default Value 로 들어가게 됩니다.

해당 부분에서 발생하는 문제가 있는지 확인해보면 좋을 것 같습니다.

Kotlin 에서는 var 로 선언한 프로퍼티는 자바의 맴버 변수, getter, setter 와 동일한 기능을 합니다. 또한 이를 주 생성자의 파라미터로 둔다면 생성자 또한 생성되게 됩니다.

만약 해당 객체를 생성한 후 임의로 값을 변경할 수 있다면 어떤 일이 발생할까요?
