# addAll method

void addAll (Map<String, dynamic> other)
override

Adds all key/value pairs of `other` to this map.

If a key of `other` is already in this map, its value is overwritten.

The operation is equivalent to doing `this[key] = value` for each key and associated value in other. It iterates over `other`, which must therefore not change during the iteration.

## Implementation

    void addAll(Map<String, dynamic> other) {
      throw new UnsupportedError("Not supported");
    }
