A listenable that wraps around the PageController.

Page Controller Listenable

A listenable that wraps around the PageController.

This listenable extends ValueListenable<double> and can be quickly passed into animations, where the type check would fail against the PageController.

Example

class ExampleWidgetState extends State<ExampleWidget> {
  late PageController _pageController;
  late PageControllerListenable _pageControllerListenable;

  @override
  void initState() {
    _pageController = PageController();
    _pageControllerListenable = PageControllerListenable(_pageController);
    super.initState();
  }

  @override
  void dispose() {
    _pageControllerListenable.dispose();
    _pageController.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return WidgetWithSomeAnimation(
      animation: _pageControllerListenable,
      child: ...
    );
  }
}

There's a hook included too.

Hook example

class ExampleWidget extends HookWidget {
  @override
  Widget build(BuildContext context) {
    final pageController = usePageController();
    final pageControllerListenable = usePageControllerListenable(pageController);

    return WidgetWithSomeAnimation(
      animation: pageControllerListenable,
      child: ...
    );
  }
}
