generate static method
Generates a random alphanumeric string
length
characters long.
Implementation
static String generate({int length = 32, int? seed, bool secure = false}) {
assert(length > 0);
assert(!secure || seed == null, 'Secure [Random]s don\'t accept seeds.');
final random = secure ? Random.secure() : Random(seed);
final charCodes = List<int>.generate(length, (_) {
late int codeUnit;

break;
case 1:
codeUnit = random.nextInt(26) + 65;
break;
case 2:
codeUnit = random.nextInt(26) + 97;
break;
}
return codeUnit;
});
