containsKey method

  1. @override
bool containsKey(
  1. K key
)
override

returns true if the item is available in the cache. Take this with a grain of salt since the item may be evicted before it will be retrieved. It is better to use get and check for null returns.

Implementation

@override
bool containsKey(K key) {
  return _internalMap.containsKey(key);
}
