There's no need to explicitly type the constructor parameter in this case. Maybe
it's time to give it a better name than _s too?

Done and good call. After I sent this out, I realized making it a nicely named
public field would let you get at the raw message, which toString() doesn't.
Renamed to "message".

+  String toString() => "FormatException: '$_s'";
   final String _s;
 }
