dart - 如何从 Dart 的范围中获取随机数？

Question

如何在类似于 c# Random.Next(int min, int max); 的范围内获得随机数；

Answer 1

import 'dart:math';

final _random = new Random();

/**
 * Generates a positive random integer uniformly distributed on the range
 * from [min], inclusive, to [max], exclusive.
 */
int next(int min, int max) => min + _random.nextInt(max - min);
