If LiveData<T: Any>’s getter returns T?, but the setter only takes T values (non null), and I provide a default value right away (val a = MutableLiveData<String>().apply { value = “” }) - is there any way there the livedata’s value can be null again? Like some under the hood stuff happening? Would be nice it I could call value?.copy() of data class live data without the ? and a default value after that

You might want to subclass

MutableLiveData

with a class whose constructor takes a parameter (i.e. the default value) and then overrides the

getValue

function, asserting it's not null

Yes my plan was to do exactly that. Thank you 🙂
