Flutter module local notification foreground push in ios not working

Flutter module을 가지고 이것 저것 테스트 하는데 이상한 현상이 있어서 기록해요. 

Flutter module에서 Local notification 기능을 넣고, 그 상태로 iOS에서 로컬 푸시를 보내면 Foreground background 아주 잘 오는데 이상하게 이 module을 다시 native iOS에 넣어서 테스트를 하면 foreground 에서는 푸시가 오지 않는 현상이 있습니다. 

이것을 해결하기위해 아래 처럼 코드를 수정을 하면 정상 동작을 확인할수 있습니다.
