Current approach for Scoping State?

[opsb]

The example at https://rearch.gsconrad.com/flutter/scoping-state shows

(int, void Function()) scopedCount(WidgetHandle use, int startingCount) {
  final (count, setCount) = use.state(startingCount);
  return (count, () => setCount(count + 1));
}

but currently WidgetHandle doesn't appear to have the use.state (or use.data). Is there an approach to achieve the same with the current API?

Those are defined as extension methods over in rearch; thus:

import 'package:rearch/rearch.dart';

Ah yep, I just discovered that. It seems vscode isn't able to discover the import.
