import 'package:dart_random_choice/dart_random_choice.dart';

void main() {
const List<String> foodOptions = ['burger', 'pizza', 'salad'];
const List<double> weights = [10, 20, 0.4];
String whatToEat = randomChoice<String>(foodOptions, weights);
// I probably won't be eating a salad...


Set<Point> cardinalDirections = {
Point(0, 1), Point(0, -1),
Point(1, 0), Point(-1, 0),
};
Point direction = randomChoice<Point>(cardinalDirections);
// Each direction is equally likely.


Runes alphabet = Runes('abcdefghijklmnopqrstuvwxyz');
int charCode = randomChoice<int>(alphabet);
String char = String.fromCharCode(charCode);
// Any iterable works!
