A fixed-length list of 16-bit signed integers that is viewable as a TypedData.
For long lists, this implementation can be considerably more space- and time-efficient than the default List implementation.

Constructors
- Int16List(int length)
- Creates an Int16List of the specified length (in elements), all of whose elements are initially zero.
- Int16List.fromList(List<int> elements)
-
Creates a Int16List with the same length as the
elements
list and copies over the elements. - Int16List.view(ByteBuffer buffer, [int offsetInBytes = 0, int length])
-
Creates an Int16List view of the specified region in
buffer
.
