maxByOrNull<R extends Comparable<R>> method

E? maxByOrNull<R extends Comparable<R>>(R selector(E element))

Implementation

E? maxByOrNull<R extends Comparable<R>>(R Function(E element) selector) {
  if (isEmpty) return null;
  var maxElement = first;
  var maxValue = selector(maxElement!);
  for (final element in this) {
    final value = selector(element);
    if (value.compareTo(maxValue) > 0) {
      maxElement = element;
      maxValue = value;
    }
  }
  return maxElement;
}
