Identity class

An Identity exists solely to return the specified argument Status from its update() method. An Identity compares equal to another Identity if they are both constructed with the same Status.

Example:

void identityExample() {
  final success = const Identity(Status.success);
  // always returns the specified Status
  assert(success.update() == Status.success);
  assert(success.update() == Status.success);

  final otherSuccess = Identity(Status.success);
  // two instances with the same Status compare as equal
  assert(success == otherSuccess);
  assert(success.update() == otherSuccess.update());
}
