remove method

@override bool remove(Object? value)

Removes value from the set.

Returns true if value was in the set, and false if not. The method has no effect if value was not in the set.

If value requires removal multiple times, the required removal counter is decremented. Otherwise, value is removed.

Implementation

@override
bool remove(Object? value) {
  if (!_inner.contains(value)) return false;
  final newCount = _counts[value]! - 1;
  if (newCount == 0) {
    _inner.remove(value);
    _counts.remove(value);
  } else {
    _counts[value as E] = newCount;
  }
  return true;
}
