operator []= method

  1. @override
void operator []=(
  1. K key,
  2. V 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

@override
void operator []=(K key, V value) {
  if (_isReadonly) {
    throw UnsupportedError('Attempted to change a read-only map field');
  }
  ArgumentError.checkNotNull(key, 'key');
  ArgumentError.checkNotNull(value, 'value');
  _wrappedMap[key] = value;
}
