# removeWhere method

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

    void removeWhere(bool test(K key, V value)) {
      var keysToRemove = <K>[];
      for (var key in keys) {
        if (test(key, this[key] as V)) keysToRemove.add(key);
      }
      for (var key in keysToRemove) {
        this.remove(key);
      }
    }
