Multiplatform LiveData

Multiplataforma livedata

Réimplema de Android Ledatas en Kotlin-Multiplatform

Envuelve los reales Ledatas en Android y usa un patrón observable en iOS

Funciona exactamente igual que Android Ledatas: https://developer.android.com/topic/libraries/architecture/livedata

KLiveData<T> LEER SOLO KMutableLiveData<T> LEER / ESCRIBIR KMediatorLiveData<T> KLiveData OBSERVA

Transformaciones como map y switchmap también están disponibles

 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
    }
}
