)
Creates an Int8List view of the specified region in the specified
byte buffer. Changes in the Int8List will be visible in the byte
buffer and vice versa. If the offsetInBytes
index of the region is not
specified, it defaults to zero (the first byte in the byte buffer).
If the length is not specified, it defaults to null, which indicates
that the view extends to the end of the byte buffer.
Throws RangeError if offsetInBytes
or length
are negative, or
if offsetInBytes
+ (length
* elementSizeInBytes) is greater than
the length of buffer
.
