# Multiplatform LiveData

Réimplémentation of android LiveDatas on kotlin-multiplatform

It wraps reals livedatas on Android, and uses an Observable-Pattern on iOS

It works exactly the same as Android LiveDatas : https://developer.android.com/topic/libraries/architecture/livedata

`KLiveData` Read only observable

`KMutableLiveData` Read / Write observable

`KMediatorLiveData` Read / Write observable, capable of listen `KLiveData`

Transformations like `map` and `switchmap` are available too

```kotlin

class MainViewModel(val premiumManager: PremiumManager) {

    private val _viewState = KMediatorLiveData()

    

    val viewState = KLiveData()

        get() = _viewState

    init {

        _viewState.value = ViewState("not premium")

        _viewState.addSource(premiumManager.premium()) {

            if(it) {

                _viewState.value = ViewState("premium")

            } else {

                _viewState.value = ViewState("not premium")

            }

        }

    }

}

```

```kotlin

class ViewState(

    val userStatus: String

)

```

```kotlin

class PremiumManager {

    private val premium = KMutableLiveData()

    fun premium() : KLiveData {

        return premium

    }

    fun becomePremium() {

        premium.value = true

    }

    init {

        //default value

        premium.value = false

    }

}

```

 [ ![Download](https://api.bintray.com/packages/florent37/maven/multiplatform-livedata/images/download.svg) ](https://bintray.com/florent37/maven/multiplatform-livedata/_latestVersion)

Uses a kotlin reimplementation of livedatas

```groovy

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

```

## android

Uses inside the jetpack's LiveDatas

 [ ![Download](https://api.bintray.com/packages/florent37/maven/multiplatform-livedata/images/download.svg) ](https://bintray.com/florent37/maven/multiplatform-livedata/_latestVersion)

```groovy

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

```

You can retrieve the real livedatas stored inside :

```

KLiveData.toLivedata : LiveData

KMutableLiveData.toMutableLiveData : MutableLiveData

KMediatorLiveData.toMediatorLivedata : MediatorLivedata

```

And create KLiveDatas from jetpacks LiveDatas

```

LiveData.toKLivedata: KLiveData

MutableLiveData.toKMutableLiveData: KMutableLiveData

MediatorLiveData.toKMediatorLivedata: KMediatorLiveData

```
