A fixed-length list of 8-bit unsigned integers.
For long lists, this implementation can be considerably more space- and time-efficient than the default List implementation.
Integers stored in the list are clamped to an unsigned eight bit value. That is, all values below zero are stored as zero and all values above 255 are stored as 255.

Constructors
- Uint8ClampedList(int length)
-
Creates a Uint8ClampedList of the specified length (in elements), all of whose elements are initially zero.
factory - Uint8ClampedList.fromList(List<int> elements)
-
Creates a Uint8ClampedList of the same size as the
