CopyWith set null?

[jopmiddelkamp]

How does the copyWith method understand which argument has been set to null and, as a result, knows to reset that property?

It's relying on default values.

copyWith({param = sentinel}) {
  if (param!= sentinel) 
}

Thanks for your quick reply! I think I see what you mean now!
