var productList = MutableLiveData<ArrayList<Fnblist>>() fun add(subitem: Subitem, position: Int) { productList.value?.get(position)?.subitems?.get(0)?.count = 2 } not observing on property change.. need help

Because LiveData don’t know if the content of the object changed.

Then. What's solutions for this

add

productList.setValue(productList.value)

it only observes changes of the list, not the items within the list
