# removeWhere method

1. @override

void removeWhere(

1. bool test(
   1. K key,
   2. V value
   )

)
override

Removes all entries of this map that satisfy the given `test`.

    final terrestrial = <int, String>{1: 'Mercury', 2: 'Venus', 3: 'Earth'};
    terrestrial.removeWhere((key, value) => value.startsWith('E'));
    print(terrestrial); // {1: Mercury, 2: Venus}

## Implementation

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