Multiplatform LiveData

Multiplatform Livedata

Kotlin-Multiplatform에서 Android Livedatas의 réimplémentation

그것은 안드로이드에 실제 살아있는 실제를 랩핑하고 iOS에서 관찰 가능한 패턴을 사용합니다.

Android Livedatas : https://developer.android.com/topic/libraries/architecture/livedata와 정확히 동일하게 작동합니다.

KLiveData<T> 읽기 전용 관찰 가능한 KMutableLiveData<T> 읽기 / 쓰기 관찰 가능한 KMediatorLiveData<T> 관찰 가능성을 읽고 쓰기, KLiveData 들을 수 있습니다.

map 및 switchmap 과 같은 변환도 사용할 수 있습니다

 class MainViewModel ( val premiumManager : PremiumManager ) {
    private val _viewState = KMediatorLiveData < ViewState >()
    
    val viewState = KLiveData < ViewState >()
        get() = _viewState

    init {
        _viewState .value = ViewState ( " not premium " )

        _viewState .addSource(premiumManager.premium()) {
            if (it) {
                _viewState .value = ViewState ( " premium " )
            } else {
                _viewState .value = ViewState ( " not premium " )
            }
        }
    }
}

 class ViewState (
    val userStatus : String
)

 class PremiumManager {
    private val premium = KMutableLiveData < Boolean >()
    fun premium () : KLiveData < Boolean > {
        return premium
    }

    fun becomePremium () {
        premium.value = true
    }

    init {
        // default value
        premium.value = false
    }
}

기계적 인조 인간

Jetpack의 Livedatas 내부에 사용됩니다

implementation " com.github.florent37:multiplatform-livedata-android:1.0.0 "

내부에 저장된 실제 LIVEDATA를 검색 할 수 있습니다.

 KLiveData<T>.toLivedata : LiveData<T>

KMutableLiveData<T>.toMutableLiveData : MutableLiveData<T>

KMediatorLiveData<T>.toMediatorLivedata : MediatorLivedata<T>

그리고 Jetpacks Livedatas에서 Klivedatas를 만듭니다

 LiveData<T>.toKLivedata: KLiveData<T>

MutableLiveData<T>.toKMutableLiveData: KMutableLiveData<T>

MediatorLiveData<T>.toKMediatorLivedata: KMediatorLiveData<T>
