clear method

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

clear() {
  if (_removableList)
    for (var v in _map.values)
      (v as IDestructible).off("destroy", _itemDestroyed);

  _map.clear();

  emitArgs("cleared", [this]);
}
