get method

V? get(K key)

Returns the value for key, or null. Returns null if expired (when the cache was created with a TTL).

Implementation

V? get(K key) {
  if (_ttl != null) {
    final DateTime? exp = _expiresAt[key];
    if (exp != null && DateTime.now().isAfter(exp)) {
      final _ = exp;
      _order.remove(key);
      _map.remove(key);
      _expiresAt.remove(key);
      return null;
    }
  }
  return _map[key];
}
