LiveData emit / emitSource

LiveData를 사용하다 보면 가끔 emit / emitSource 라는 애들을 보게 됩니다.

 

설명을 찾아보면 복잡하게 되어 있는데

 

emit -> 값을 반환

emiteSource -> livedata를 반환 

 

이렇게 생각해주시면 됩니다.

 

아래는 예제입니다.

 

gradle에 넣어주고

def lifecycle_version = '2.4.1'

implementation "androidx.lifecycle:lifecycle-livedata-ktx:$lifecycle_version"
