Hi, is there a reason to not mark null-safety version as stable?
p.s. Thanks for your work, I'm using your package everywhere...
Some useful combinators could be added:
One of the breaking changes of adopting null safety is the following.
final n = Some(3);
// pass
n.fold(() => null, (x) => x);
// can't pass
n.getOrElse(null);
Current getOrElse
implementation is this.
A getOrElse(A caseElse) => fold(() => caseElse, (A a) => a);
I couldn't find the signature accepting n.getOrElse(null)
. It can be bypassed by using fold
directly so it doesn't require an immediate action, but it can be a consideration point.
It seems the package does not support NNBD and has no branch for it. Can I make a PR?
Foreigners who doesn't know background of the names may try finding constructors from Either
and Option
.
Either
and Option
is closed class, and inseparable from the derived types. I think this is adoptable and can help beginners.
