getRandomBytes function
Generates a list of random bytes of the specified length.
length The desired length of the byte list.
Returns a Uint8List containing cryptographically secure random bytes.
Implementation
Uint8List getRandomBytes(int length) {
final r = Uint8List(length);
for (var i = 0; i < length; i++) {
r[i] = _random.nextInt(255);
}
return r;
}
