operator []= method

void operator []=(
  1. K key,
  2. V valueToSet
)

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.

void operator []=(K key, V valueToSet) {
  if (value == null) return null;
  update((_) => value?[key] = valueToSet);
}
