ViewProvider<T> class
The ViewProvider is the only provider that can watch other providers.
Its builder is similar to a normal Provider.
A common use case is to define a view model that depends on many providers.
Don't worry about the ref, you can use it freely inside any function.
The ref will never become invalid.
