Greetings all! Is it possible that a `LiveData` with a backing property (MutableLiveData) inside the ViewModel to `Observe` and `Add` to an ArrayList can cause a race condition and a `Lock` is required? Provided that the ArrayList will get its value from a callback.

Uh, with the simple setup you've described, no it won't cause a race condition.
Observers are called on the singular main thread.

Here is my exact question if anyone would like to answer:
