MyDoc class

나의 문서가 변하면 위젯을 re-build 한다.

주의, 이 위젯은 로그인한 사용자의 문서 /users/<uid> 를 listen 하지 않는다. 정확히는 UserService.instance.changes 를 listen 한다.

즉, DB 업데이트가 있으면 listener 에 의해서 UserService.instance.user 가 업데이트 되고, UserService.instance.changes 이벤트가 발생한다.

사용자 로그인을 하지 않았거나, 로그인 중이거나, 사용자 문서가 존재하지 않으면, builder 파라메타로 전달되는 House User 는 null 이 될 수 있다.

사용자가 로그 아웃이나 계정을 변경하는 경우, UserService.instance.user 가 변하고, UserService.instance.changes 이벤트가 발생하여 잘 동작한다.

initialData 에 UserService.instance.changes 를 사용하여, 깜빡거림이 없도록 한다.
