Difference between LiveData, MutableLiveData

Question

I know that the MutableLiveData extends LiveData, but what is the difference between them (in usage). What are appropriate use cases, means when to use the correct one from the two?

Use Live Data when you don't intend to modify it in the future otherwise Mutable Live Data — Tarun Sharma, Nov 29 '20 at 07:35

LiveData is immutable while MutableLiveData is mutable. MutableLiveData extends LiveData and provides methods like setValue() and postValue().

`LiveData` provides methods `setValue()` and `postValue()` too but they are protected, not public – pskink Oct 12 '18 at 05:45
Please why are they protected? – George Udosen Feb 15 '19 at 00:42

Because it is not mutable. – ecth Jun 18 '19 at 17:10

@GeorgeUdosen Because they are available to the subclass (or creating classes like `MutableLiveData`) but are not part of the public interface. – Ellen Spertus Mar 10 '20 at 17:12
