getMeta method

@override Future<AtMetaData?> getMeta(String key)

Returns the metadata associated with key.

Implementation

@override
Future<AtMetaData?> getMeta(String key) async {
  // The earlier version returns "null" when key is not present in the
  // cache map. To preserve the existing behaviour, returning "null"
  // when KeyNotFoundException is thrown.
  try {
    return (await get(key.toLowerCase()))?.metaData;
  } on KeyNotFoundException {
    return null;
  }
}
