Multiplatform LiveData

Multiplataform Livedata

Réimplémentation of Android Livedatas em Kotlin-Multiplatform

Ele envolve Reals Livedata no Android e usa um padrão observável no iOS

Funciona exatamente da mesma forma que o Android Livedata: https://developer.android.com/topic/libraries/architecture/livedata

KLiveData<T> Leia apenas KMutableLiveData<T> leia / escreva observável KMediatorLiveData<T> leia / escreva observável, capaz de ouvir KLiveData

Transformações como map e switchmap também estão disponíveis

 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
    }
}

comum

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

iOS

Usa uma reimplementação de Kotlin de Livivedatas

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

Android

Usa dentro das Livivedatas do Jetpack

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

Você pode recuperar as verdadeiras Livivedatas armazenadas dentro:

 KLiveData<T>.toLivedata : LiveData<T>

KMutableLiveData<T>.toMutableLiveData : MutableLiveData<T>

KMediatorLiveData<T>.toMediatorLivedata : MediatorLivedata<T>

E crie klivedatas a partir de jetpacks

 LiveData<T>.toKLivedata: KLiveData<T>

MutableLiveData<T>.toKMutableLiveData: KMutableLiveData<T>

MediatorLiveData<T>.toKMediatorLivedata: KMediatorLiveData<T>
