removeWhere method

void removeWhere(
  1. bool test(
    1. K,
    2. V
    )
)

Removes entries that match the predicate.

Example:

final map = {'a': 1, 'b': 2, 'c': 3};
map.removeWhere((k, v) => v > 1); // {'a': 1}

Implementation

void removeWhere(bool Function(K, V) test) {
  final List<K> keysToRemove = <K>[];
  forEach((K key, V value) {
    if (test(key, value)) {
      keysToRemove.add(key);
    }
  });
  for (final K key in keysToRemove) {
    remove(key);
  }
}
