# Uint16List.sublistView constructor

- @Since("2.8")

Creates a Uint16List view on a range of elements of `data`

.

Creates a view on the range of `data.buffer`

which corresponds
to the elements of `data`

from `start`

until `end`

.
If `data`

is a typed data list, like Uint16List, then the view is on
the bytes of the elements with indices from `start`

until `end`

.
If `data`

is a ByteData, it's treated like a list of bytes.

If provided, `start`

and `end`

must satisfy

0 ≤ `start`

≤ `end`

≤ *elementCount*

where *elementCount* is the number of elements in `data`

, which
is the same as the List.length of a typed data list.

If omitted, `start`

defaults to zero and `end`

to *elementCount*.

The start and end indices of the range of bytes being viewed must be multiples of two.

## Implementation

```
@Since("2.8")
factory Uint16List.sublistView(TypedData data, [int start = 0, int? end]) {
int elementSize = data.elementSizeInBytes;
end = RangeError.checkValidRange(
start, end, data.lengthInBytes ~/ elementSize);
int byteLength = (end - start) * elementSize;
if (byteLength % bytesPerElement != 0) {
throw ArgumentError("The number of bytes to view must be a multiple of " +
"$bytesPerElement");
}
return data.buffer.asUint16List(data.offsetInBytes + start * elementSize,
byteLength ~/ bytesPerElement);
}
```
