operator []= method

@override void operator []=(K key, V value)

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

@override
void operator []=(K key, V value) {
  if (_isReadOnly) {
    throw UnsupportedError('Attempted to change a read-only map field');
  }
  if (_checkKey != null) {
    _checkKey(key);
  }
  if (_checkValue != null) {
    _checkValue(value);
  }
  _wrappedMap[key] = value;
}
