MutableLiveData<T> class

An Updateable LiveData as the name suggests

This is defined separately from LiveData to avoid access to consumers of the LiveData(UI) to modify the state directly You'd expose a LiveData<T> publicly from a ViewModel while backing it using a private MutableLiveData<T> like this

class CounterViewModel extends ViewModel {
  final MutableLiveData<int> _counter = MutableLiveData(0);

  LiveData<int> get counter => _counter;

  void increment() {
    _counter.value++;
  }
}
