Has anyone implemented a Kotlin solution to creating non-nullable LiveData types? Trying to think of the best way to do this.. Right now I have an extension function which will get the value only if it's not null, otherwise throw (as the value should never be null), but I'd much rather do it as a functionality of the setter and force the LiveData to have an initialization value as well as not being able to set it to null.

My solution is to use

Flow

and bridge it to

LiveData

, not exposing

MutableLiveData

, and I observe only notNull values, with an extension (that I can link if you want)

Please do! That sounds very promising

I think AndroidX LiveData KTX now has these but I'm not sure. Anyway, here are my extensions: https://github.com/LouisCAD/Splitties/blob/de82f24a60bb92198a120634971c41e86dc72c24/modules/arch-lifecycle/src/androidMain/kotlin/splitties/arch/lifecycle/LiveData.kt#L21 The obsolete API annotations are because I plan to remove overlap with KTX artifacts. To bridge a

Flow

to a

LiveData

, here's what you can do with latest LiveData KTX (should be in stable now):

val yourLiveData = liveData {
    myFlow.collect { myData ->
        /*this@liveData.*/emit(myData)
    }
}

LiveData KTX, you mean the third party library? Or is this a part of AndroidX?
