decodeObject<T extends Coding> method Null safety

T? decodeObject<T extends Coding>(
  1. String key,
  2. T inflate(
      )
    )

    Returns the instance of T associated with key.

    inflate must create an empty instance of T. The value associated with key must be a KeyedArchive (a Map). The values of the associated object are read into the empty instance of T.

    Implementation

    T? decodeObject<T extends Coding>(String key, T Function() inflate) {
  final val = _getValue(key);
  if (val == null) {
    return null;
  }

  if (val is! KeyedArchive) {
    throw ArgumentError(
      "Cannot decode key '$key' into '$T', because the value is not a Map. Actual value: '$val'.",
    );
  }

  return _decodedObject(val, inflate);
}
