# operator []= method Null safety

void operator []= (

1. String key,
2. dynamic value

)
override

Associates the `key` with the given `value`.

If the key was already in the map, its associated value is changed. Otherwise the key/value pair is added to the map.

## Implementation

    void operator []=(String key, dynamic value) {
      throw new UnsupportedError("Not supported");
    }
