mapEntryKeys<K, V> static method

ConvertingComparator<MapEntry<K, V>, K> mapEntryKeys<K, V>(
  1. Comparator<K> comparator
)

Creates a comparator that compares MapEntry objects by their keys.

🔧 Example:

final entries = [
  MapEntry('c', 1),
  MapEntry('a', 3),
  MapEntry('b', 2),
];
entries.sort(ConvertingComparator.mapEntryKeys((a, b) => a.compareTo(b)));
// Sorted by key: a, b, c

Implementation

static ConvertingComparator<MapEntry<K, V>, K> mapEntryKeys<K, V>(Comparator<K> comparator) {
  return ConvertingComparator<MapEntry<K, V>, K>(comparator, _MapEntryKeyConverter<K, V>());
}
