ValueNotifier is a class that extends ChangeNotifier, which can hold a value and notify the widgets to any listener whenever the holding value gets changed.
You can find out more about the Flutter app development services page.
1.) Create a Scaffold.
2.) Create a Value Notifier.
3.) Change ValueNotifier values and use ValueListenableBuilder.
Inside Scaffold widgets, it Implements the basic material design visual layout structure. First, initialize the main app as a stateless widget.
This class provides APIs for showing drawers and bottom sheets. We can add the background color inside the scaffold widget.
It also supports special Material Design components, such as Drawers, AppBars, and SnackBars.
Value Notifier is used to create a new file value_notifiers.dart, that will hold all the valueNotifiers in one file. For this, we need to import value_notifiers.dart otherwise it will give an error.
However, We can use ValueListenableBuilder which returns only a Listenable and no ValueListenable and ValueListenableBuilder expects a Value Changenotifier. We can use AnimatedBuilder instead which despite its name is just a ListenableBuilder.
We can now run the app on how to create ValueNotifier in a flutter.
Hope this blog helps you to create ValueNotifier in a flutter.
So, I hope it will help you understand and get a brief idea about it.
