Multiplatform LiveData

Multiplatform livedata

Réimplémentation Android Livedatas di Kotlin-Multiplatform

Itu membungkus real livedata di android, dan menggunakan pola yang dapat diamati di iOS

Ini bekerja persis sama dengan Android Livedatas: https://developer.android.com/topic/libraries/architecture/livedata

KLiveData<T> BACA Hanya Observable KMutableLiveData<T> Baca / Tulis KMediatorLiveData<T> Baca / tulis yang dapat diamati, mampu mendengarkan KLiveData

Transformasi seperti map dan switchmap juga tersedia

 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
    }
}

Unduh

Tambahkan repositori

repositories {
    maven { url  " https://dl.bintray.com/florent37/maven " }
}

umum

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

iOS

Menggunakan reimplementasi Kotlin dari Livedata

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

Android

Penggunaan di dalam livedata jetpack

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

Anda dapat mengambil Livedata asli yang disimpan di dalam:

 KLiveData<T>.toLivedata : LiveData<T>

KMutableLiveData<T>.toMutableLiveData : MutableLiveData<T>

KMediatorLiveData<T>.toMediatorLivedata : MediatorLivedata<T>

Dan membuat klivedata dari jetpacks livedata

 LiveData<T>.toKLivedata: KLiveData<T>

MutableLiveData<T>.toKMutableLiveData: KMutableLiveData<T>

MediatorLiveData<T>.toKMediatorLivedata: KMediatorLiveData<T>
