# updateAll method

1. @override

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

    @override
    void updateAll(V Function(K key, V value) update) {
      final updatedEntries = <K, V>{};
      forEach((key, value) {
        updatedEntries[key] = update(key, value);
      });
      updatedEntries.forEach((key, value) {
        this[key] = value; // Update in place
      });
    }
