asFloat64x2List abstract method Null safety

Float64x2List asFloat64x2List(
  1. [int offsetInBytes = 0,
  2. int? length]
)

Creates a Float64x2List view of a region of this byte buffer.

The view is backed by the bytes of this byte buffer. Any changes made to the Float64x2List will also change the buffer, and vice versa.

The viewed region start at offsetInBytes, which must be 128-bit aligned, and contains length 128-bit integers. If length is omitted, the range extends as far towards the end of the buffer as possible - if lengthInBytes is not divisible by 16, the last bytes can't be part of the view.

The start index and length must describe a valid 128-bit aligned range of the buffer:

  • offsetInBytes must not be negative,
  • offsetInBytes must be divisible by sixteen,
  • length must not be negative, and
  • offsetInBytes + length * 16 must not be greater than lengthInBytes.

Implementation

Float64x2List asFloat64x2List([int offsetInBytes = 0, int? length]);
