temen2, ada yang pernah ngalamin gini:

pengen add by index or by item / element, buat list of SingeLiveEvent

val movieList = SingleLiveEvent<MutableList>()

movieListFromApi.forEachIndexed { index, movie -> movieList.value[i] = movie // ini ga bisa diakses

kalo ada yang nemuin error begindrang: Caused by android.support.v4.app.Fragment$InstantiationException: Unable to instantiate fragment id.gits.jasaraharjainternal.mvvm.santunan.listsantunan.ListSantunanFragment: could not find Fragment constructor

make sure ketika bikin fragment, ga perlu pake default constructor yaaa, dan buat pass / receive data dari luar ke fragment, pake arguments aja yaaa & pake singleton pattern newInstance(data: Int) = TestFragment().withArgs { putInt(ARGUMENT_TYPE, data) }
