public View onCreateView(@NonNull
                         LayoutInflater inflater,
                         @Nullable
                         ViewGroup container,
                         @Nullable
                         Bundle savedInstanceState)

This override of onCreateView inflates the Fragment using findViewById(), retrieves a reference to the MainViewModel and starts the loading animation.

Overrides:

onViewCreated

public void onViewCreated(@NonNull
                          View view,
                          @Nullable
                          Bundle savedInstanceState)
