*<Null safety>*

int lowerBoundBy <K extends Comparable<K>>(E element, K keyOf(E), [int start = 0, int? end])

Implementation

int lowerBoundBy<K extends Comparable<K>>(E element, K Function(E) keyOf,
        [int start = 0, int? end]) =>
    algorithms.lowerBoundBy<E, K>(
        this, keyOf, compareComparable, element, start, end);
