Description:

random string

random_string #
Simple library for generating random ascii strings.
Design goals and limitations #
While this package provides randomBetween for convenience, as the name implies, the design goal of this package
is for random generation of ascii strings, particularly for testing and not for cryptographic purposes.
With that stated, consider an alternative means of random number generation if your needs fall outside these goals
and limitations.
Usage #
A simple usage example:
import 'package:random_string/random_string.dart';
import 'dart:math' show Random;

main() {
print(randomBetween(10, 20)); // some integer between 10 and 20 where 0 <= min <= max <= 999999999999999
print(randomNumeric(4)); // sequence of 4 random numbers i.e. 3259
print(randomString(10)); // random sequence of 10 characters i.e. e~f93(4l-
print(randomAlpha(5)); // random sequence of 5 alpha characters i.e. aRztC
print(randomAlphaNumeric(10)); // random sequence of 10 alpha numeric i.e. aRztC1y32B

var r = Random.secure();
print(randomBetween(10, 20, provider: CoreRandomProvider.from(r))); // You can use a provider from Random.
print(randomBetween(10, 20, provider: _Provider())); // Or you can implement your own.
}

class _Provider with AbstractRandomProvider {
_Provider();
double nextDouble() => 0.5;
}
