Uint16List asUint16List([int offsetInBytes = 0, int length])

Creates a Uint16List view of a region of this byte buffer.

The view is backed by the bytes of this byte buffer. Any changes made to the Uint16List will also change the buffer, and vice versa.

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

The start index and length must describe a valid 16-bit aligned range of the buffer:

  • offsetInBytes must not be negative,
  • offsetInBytes must be divisible by two,
  • length must not be negative, and
  • offsetInBytes + length * 2 must not be greater than lengthInBytes.
