operator []= method

void operator []=(
  1. String key,
  2. Object? 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

void operator []=(String key, Object? value) {
  if (value == null) {
    _properties.remove(key);
  } else {
    _properties[key] = value;
  }
}
