get method

@override Future<Uint8List?> get(String key)

Retrieves the value associated with the given key, or null if not present.

Updates hit/miss statistics accordingly. The operation is thread-safe.

Implementation

@override
Future<Uint8List?> get(String key) async {
  assert(key.isNotEmpty, 'key must not be empty');
  return await lock.synchronized(() {
    Uint8List? mapValue = map[key];
    if (mapValue != null) {
      hitCount++;
      return mapValue;
    }
    missCount++;
    return null;
  });
}
