clear method

@override void clear()

Removes all entries from the map.

After this, the map is empty.

final planets = <int, String>{1: 'Mercury', 2: 'Venus', 3: 'Earth'};
planets.clear(); // {}

Implementation

@override
void clear() {
  _context.conditionallyRunInAction(() {
    if (isEmpty) {
      return;
    }
    if (_hasListeners) {
      final removed = Map<K, V>.from(_map);
      _map.clear();
      removed.forEach(_reportRemove);
    } else {
      _map.clear();
    }
    _atom.reportChanged();
  }, _atom);
}
