Have you had a situation where you must select and rebuild the interface only to change specific fields of your ChangeNotifier?
Not convenient to use AnimatedBuilder with ChangeNotifier instead of ValueListenableBuilder?
Of course, I had to. So I made a simple extension that converts ChangeNotifier to ValueListenable and has filtering capabilities.
And transformation pipeline looks like this:
ChangeNotifier --- select & filter --> ValueListenable<Value>
For example, you can transform your AppModel and rebuild some parts of widgets when localization is changed and only when the language code has changed:
ValueListenableBuilder<Locale>( valueListenable: appModel.select<Locale>( (cn) => cn.locale, (prev, next) => prev.languageCode != next.languageCode ), builder: (context, locale, child) => Text(locale), )
Complete code of my extension:
