# Float64x2List class abstract final

A fixed-length list of Float64x2 numbers that is viewable as a TypedData.

For long lists, this implementation will be considerably more space- and time-efficient than the default List implementation.

It is a compile-time error for a class to attempt to extend or implement `Float64x2List`.

Implemented types
  - TypedDataList<Float64x2>
  - TypedData

## Constructors

Float64x2List(int length)
  Creates a Float64x2List of the specified length (in elements), all of whose elements have all lanes set to zero.
  factory
Float64x2List.fromList(List<Float64x2> elements)
  Creates a Float64x2List with the same length as the `elements` list and copies over the elements.
  factory
Float64x2List.sublistView(TypedData data, [int start = 0, int? end])
  Creates an Float64x2List view on a range of elements of `data`.
  factory
Float64x2List.view(ByteBuffer buffer, [int offsetInBytes = 0, int? length])
  Creates a Float64x2List view of the specified region in `buffer`.
