min<T> function

T min <T>(Iterable<T> i, [ Comparator<T> compare ])

Returns the minimum value in i, according to the order specified by the compare function, or null if i is empty.

The compare function must act as a Comparator. If compare is omitted, Comparable.compare is used. If i contains null elements, an exception will be thrown.

Implementation

T min<T>(Iterable<T> i, [Comparator<T> compare]) {
  if (i.isEmpty) return null;
  final Comparator<T> _compare = compare ?? Comparable.compare;
  return i.reduce((a, b) => _compare(a, b) < 0 ? a : b);
}
