Multiplatform LiveData

multiplatform livedata

redimplémentation من Android Livedatas على Kotlin-Multiplatform

يلف readatas على Android ، ويستخدم نماذج يمكن ملاحظتها على iOS

إنه يعمل تمامًا مثل Android Livedatas: https://developer.android.com/topic/libraries/architecture/livedata

KLiveData<T> اقرأ فقط KMutableLiveData<T> قراءة / كتابة KMediatorLiveData<T> القراءة / الكتابة يمكن ملاحظتها ، قادرة على الاستماع KLiveData

تتوفر التحولات مثل map و switchmap أيضًا

 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
    }
}
