Erkrankung von Android Livedatas auf Kotlin-Multiplattform
Es wickelt Reals Livedatas auf Android und verwendet ein beobachtbares Muster auf iOS
Es funktioniert genauso wie bei Android LivedAtas: https://developer.android.com/topic/libraries/architecture/livedata
KLiveData<T> Lesen Sie nur beobachtbare KMutableLiveData<T> Read / Write Observable KMediatorLiveData<T> Read / Write Observable, Hören Sie KLiveData in der Lage
Transformationen wie map und switchmap sind ebenfalls verfügbar
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
}
