@override Future<String?> load(String key)

Loads the value associated with the given key.

Returns null if no value exists for the key. Returns the serialized string if a value exists.

Throws an exception if the load operation fails.

Implementation

@override
Future<String?> load(String key) async {
  loadCount++;
  if (loadDelay != null) await Future<void>.delayed(loadDelay!);
  if (loadError != null) throw loadError!;
  return _data[key];
}
