Side Effects with ValueNotifier

Did you know?

By registering a ValueNotifier listener, you can perform various side effects such as:

• Updating a ScrollController, PageController, AnimationController, etc.
• Showing a dialog
• Navigating to another route

Note: This works with ChangeNotifier, too. 💡

Important: side effects should never be performed from the build method.
