Float64List class
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) factory
- Creates a Float64List of the specified length (in elements), all of whose elements are initially zero. [...]
- Float64List.fromList(List<
double> elements)factory - Creates a Float64List with the same length as the
elementslist and copies over the elements. [...] - Float64List.sublistView(TypedData data, [int start = 0, int? end]) factory
- Creates a Float64List view on a range of elements of
data. [...] - Float64List.view(ByteBuffer buffer, [int offsetInBytes = 0, int? length]) factory
- Creates a Float64List view of the specified region in
buffer. [...]
