"Named Argument Constructor" option missing in Generate menu for Flutter in Giraffe

[Wasmund1]

Steps to Reproduce

In a Flutter Project when right clicking a class and then clicking Generate (or simply CMD N) the option "Named Argument Constructor" is missing in Giraffe.

In earlier versions you could use this to create a constructor for this class:

class Foo{ final String bar; }

that would look like this :

const Foo({ required this.bar, });

This feature was added in https://github.com/dart-lang/sdk/commit/fa5d596d6d592be3a8a065df12ea811392a8553c. Looking at the list of versions, it was first available in 3.1.0-196.0.dev, and you use Dart version 3.0.5.

Closing, since this is not a plugin issue.

@Wasmund1 if you need further assistance on this topic, post to dart-lang/sdk

My bad this option as shown above came from the Dart Data Class Plugin
