sortByNumber<T> static method

void sortByNumber<T>({ required List<T> items, required num by(T a), bool descending = false, })

Sorts the given list by the given parameter by. Default sorting order is ascending. This can be changed by setting the descending to true.

Implementation

static void sortByNumber<T>({
  required List<T> items,
  required num Function(T a) by,
  bool descending = false,
}) {
  for (int i = 0; i < items.length; i++) {
    for (int j = i; j < items.length; j++) {
      if (descending) {
        if (by(items[i]) < by(items[j])) {
          dynamic currentValue = items[j];
          items[j] = items[i];
          items[i] = currentValue;
        }
      } else {
        if (by(items[i]) > by(items[j])) {
          dynamic currentValue = items[j];
          items[j] = items[i];
          items[i] = currentValue;
        }
      }
    }
  }
