thenComparing method

Comparator<T> thenComparing(
  1. Comparator<T> other
)

Chains another comparator to be used if this comparator returns 0 (equality).

If compare(a, b) returns 0, the other comparator will be used.

Example

final byLength = Comparator.comparing((s) => s.length);
final thenAlpha = byLength.thenComparing(Comparator.naturalOrder<String>());

final list = ['foo', 'bar', 'baz'];
list.sort(thenAlpha.compare);
print(list); // [bar, baz, foo]

Implementation

Comparator<T> thenComparing(Comparator<T> other) => _ChainedComparator(this, other);
