# updateAll method

void updateAll(

1. V update(
   1. K key,
   2. V value
   )

)
override

Updates all values.

Iterates over all entries in the map and updates them with the result of invoking `update`.

    final terrestrial = <int, String>{1: 'Mercury', 2: 'Venus', 3: 'Earth'};
    terrestrial.updateAll((key, value) => value.toUpperCase());
    print(terrestrial); // {1: MERCURY, 2: VENUS, 3: EARTH}

## Implementation

    void updateAll(V update(K key, V value)) {
      _map.updateAll(update);
    }
