thank you for the video!

What does child parameter do?

[@legardemontcho6739]

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?

[@ChrisC97232]

I think the package States_rebuilder uses this under the hood.
Very powerful stuff

[@saccarus5685]

What benefit does using this provide over setstate?

[@ziadahmed6807]

setState rebuilds the whole widget tree. On the other hand using the value listenable builder rebuilds only the child with the new value

[@saccarus5685]

​@Ziad Ahmed that's nice! Less redraws are always better

[@phuongtran-qh5kq]

It also react to changes, we can return different widgets reactively

[@kasimcan]

Hi there, how can I ensure that this number doesn't reset when I exit the application?

[@FlutterMapp]

Check the new video on this channel (Data architechture). We use shared preference to save data locally 👍

[@lumiplex404]

@@FlutterMapp can you mention the link here ???

[@phuongtran-qh5kq]

@@lumiplex404 check for sharepreference package. It will store data in your phone and will not get deleted unless you want so

[@ahmedsherif948]

But state management much stronger than this!
