ListEquality<E> class

Equality on lists.

Two lists are equal if they have the same length and their elements at each index are equal.

This is effectively the same as IterableEquality except that it accesses elements by index instead of through iteration.

The equals and hash methods accepts null values, even if the isValidKey returns false for null. The hash of null is null.hashCode.
