v4buffer method
v4buffer() Generates a RNG version 4 UUID
By default it will generate a string based off mathRNG, and will
place the result into the provided buffer
. The buffer
will also be returned.
If you wish to have crypto-strong RNG, pass in UuidUtil.cryptoRNG.
Optionally an offset
can be provided with a start position in the buffer.
The first argument is an options map that takes various configuration options detailed in the readme.
Implementation
List<int> v4buffer(
List<int> buffer, {
Map<String, dynamic> options: null,
int offset: 0,
}) {
var _buf = parse(v4(options: options));
if (buffer != null) {
buffer.setRange(offset, offset + 16, _buf);
}
return buffer;
}
