`stful` macro should not generates public API with private type

The stful macro generates a StatefulWidget with the following problematic createState implementation (assuming the generated widget has been named Foo):

@override
_FooState createState() => _FooState();

This is violating the library_private_types_in_public_api lint and bad style because among other things it exposes the private _FooState type in the API docs. Private types shouldn’t be exposed in public API. Instead, the macro should generate the following createState getter:

@override
State<Foo> createState() => _FooState();

(That’s also the what we use for that getter in the framework.)

Agree. Face this problem today when upgrading to 3.0

Great, thanks for confirming!
