What does this mean, ViewBinding has type safety and null safety?

I guess your answers are there:
https://developer.android.com/topic/libraries/view-binding#findviewbyid

View binding has important advantages over using `findViewById`:

* Null safety: Since view binding creates direct references to views, there's no risk of a null pointer exception due to an invalid view ID. Additionally, when a view is only present in some configurations of a layout, the field containing its reference in the binding class is marked with @Nullable.

* Type safety: The fields in each binding class have types matching the views they reference in the XML file. This means that there's no risk of a class cast exception.
