# asInt8List method

Int8List asInt8List ([int offsetInBytes = 0, int length ])

Creates a Int8List view of a region of this byte buffer.

The view is backed by the bytes of this byte buffer. Any changes made to the `Int8List` will also change the buffer, and vice versa.

The viewed region start at `offsetInBytes` and contains `length` bytes. If `length` is omitted, the range extends to the end of the buffer.

The start index and length must describe a valid range of the buffer:

- `offsetInBytes` must not be negative,
- `length` must not be negative, and
- `offsetInBytes + length` must not be greater than lengthInBytes.

## Implementation

    Int8List asInt8List([int offsetInBytes = 0, int length]);
