min<T extends Comparable<Object>> function

T? min<T extends Comparable<Object>>(Iterable<T> iterable)

Returns the minimum value in the given iterable. Returns null if the iterable is empty.

Implementation

T? min<T extends Comparable<Object>>(Iterable<T> iterable) {
  final iterator = iterable.iterator;
  if (!iterator.moveNext()) return null;

  T minValue = iterator.current;
  while (iterator.moveNext()) {
    if (iterator.current.compareTo(minValue) < 0) {
      minValue = iterator.current;
    }
  }
  return minValue;
}
