Flutter Dart数组固定长度分割成二维数组

标签：index List list len Dart result 数组 Flutter

将dart数组按照指定的长度分割，返回一个二维数组，实现list的split功能.

例如：

a = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19] splitList(a, 6):[[0, 1, 2, 3, 4, 5], [6, 7, 8, 9, 10, 11], [12, 13, 14, 15, 16, 17], [18, 19]]   Dart 方法代码： static List splitList(List list, int len) {     if (len <= 1) {       return [list];     }     List result = [];     int index = 1;     while (true) {       if (index * len < list.length) {         List temp = list.skip((index - 1) * len).take(len).toList();         result.add(temp);         index++;         continue;       }       List temp = list.skip((index - 1) * len).toList();       result.add(temp);       break;     }     return result;   }
