ListenableProxyProvider5<T, T2, T3, T4, T5, R extends Listenable?> class
A variation of ListenableProvider that builds its value from values obtained from other providers.
See the discussion on ChangeNotifierProxyProvider for a complete explanation on how to use it.
ChangeNotifierProxyProvider extends ListenableProxyProvider to make it work with ChangeNotifier, but the behavior stays the same. Most of the time you'll want to use ChangeNotifierProxyProvider instead. But ListenableProxyProvider is exposed in case someone wants to use a Listenable implementation other than ChangeNotifier, such as Animation.
