do you mind, Im trying to use cubit (watched your tutorial), and I am so confuse about applying it at the bottom navigation bar..

[@fozaibx1]

What if i want to use the value of the notifier in multiple screens? how can I do that?

[@meek6836]

Really nice video. When should we use ChangeNotifierBuilder and when valueNotifier?

[@dbestech]

When you want to work a on single value change use valueNotifier. It makes your code faster to run, Since you only work on one widget to rebuild. It's bound to a widget, rather than whole widget tree.

What exactly ValueNotifier provide us if we use it in our projects? Is that part clear in the video context? or missed

[@dbestech]

It gives the chance to work with individual variable properly. In once one sense it's cleaner than changenotifier

@@dbestech Thank you for your rapidly response. It is very useful then

@@dbestech btw, how about Riverpod? Is it covering the same architecture?

When people do tutorials, it's important to first explain the differences between ChangeNotifier, statefull and ValueNotifier. When will you suggest using ChangeNotifier and not ValueNotifier, for example?

@@dbestech Your article is more theoretical than practical. A reader should be able to understand your explanations with practical examples. For example, how many builds happen when you use a Consummer (Provider) compared to a ValueListenable (ValueNotifier)?

[@legardemontcho6739]

@@dbestech Thank you for your additional comments. However, to perfect your article, I suggest you use a practical example of state management where the use of the ValueNotifier is limited. This example will help the reader understand what you mean by simple and complex.
