bool containsValue(

1. dynamic value

)
override

Whether this map contains the given `value`.

Returns true if any of the values in the map are equal to `value` according to the `==` operator.

    final moonCount = <String, int>{'Mercury': 0, 'Venus': 0, 'Earth': 1,
      'Mars': 2, 'Jupiter': 79, 'Saturn': 82, 'Uranus': 27, 'Neptune': 14};
    final moons3 = moonCount.containsValue(3); // false
    final moons82 = moonCount.containsValue(82); // true

## Implementation

    bool containsValue(dynamic value) => values.any((e) => e == value);
