A fixed-length list of IEEE 754 double-precision binary floating-point numbers 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
- Float64List(int length)
-
Creates a Float64List of the specified length (in elements), all of whose elements are initially zero.
factory - Float64List.fromList(List<double> elements)
