[Flutter 2.5.0] Nested Scrollables in PageView produces error logs but app works normally #89864

iandis · 2021-09-10T15:41:41Z

Steps to Reproduce

Create a PageView that's structured like this

PageView(
  controller: _pageController,
  onPageChanged: _onPageChanged,
  children: [
     CustomScrollView(
        slivers: [
           SliverToBoxAdapter(ListView), // horizontal
           SliverToBoxAdapter(ListView), // horizontal
           SliverToBoxAdapter(ListView), // horizontal
         ],
      ),
      CustomScrollView(
         slivers: [
            SliverToBoxAdapter(ListView), // horizontal
            SliverToBoxAdapter(ListView), // horizontal
         ],
      ),
...

Run the app on web (debug mode)
Do some vertical scrolling on the first page of PageView
Move to the second page using

_pageController.animateToPage(
     index,
     duration: const Duration(milliseconds: 500),
     curve: Curves.fastLinearToSlowEaseIn,
 );

Do some vertical scrolling on the second page

Expected results:
No error logs

Actual results:
Exception thrown by the animation library

Notes:

The issue disappears if I add ScrollController to each of the CustomScrollViews
With or without the workaround, the app runs normally

Same problem here: "The provided ScrollController is currently attached to more than one ScrollPosition."

danagbemava-nc · 2021-09-13T07:50:59Z

Hi @iandis, please provide a minimal complete reproducible code sample?

Thank you

iandis · 2021-09-13T09:10:25Z

@danagbemava-nc Sure.

Code

  }
}

  const MyHomePage({Key? key}) : super(key: key);

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final PageController _pageController = PageController();
  final ValueNotifier<int> _bottomNavNotifier = ValueNotifier<int>(0);

  void _onPageChanged(int index) {
    _bottomNavNotifier.value = index;
  }

  void _movePageTo(int index) {
    _pageController.animateToPage(
      index,
      duration: const Duration(milliseconds: 500),
      curve: Curves.fastLinearToSlowEaseIn,
    );
  }

  Widget _listItemsBuilder(BuildContext context, int index) {
    return const Padding(
      padding: EdgeInsets.only(bottom: 40, right: 10),
      child: SizedBox(
        width: 200,
        child: ColoredBox(
          color: Colors.grey,
          child: Center(
            child: Text('X Item'),
          ),
        ),
      ),
    );
  }

  Widget get _sliver {
    return SliverToBoxAdapter(
      child: SizedBox(
        height: 450,
        child: ListView.builder(
          padding: const EdgeInsets.all(20),

    );
  }

    return [
      CustomScrollView(slivers: List<Widget>.filled(3, _sliver)),
      CustomScrollView(slivers: List<Widget>.filled(3, _sliver)),
    ];
  }

  List<BottomNavigationBarItem> get _bottomNavBarItems {
    return const [
      BottomNavigationBarItem(
        icon: Icon(Icons.home),
        label: 'Home',
      ),
      BottomNavigationBarItem(
        icon: Icon(Icons.person),
        label: 'Profile',
      ),
    ];
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: PageView(
        controller: _pageController,
        onPageChanged: _onPageChanged,
        children: _pages,
      ),
      bottomNavigationBar: ValueListenableBuilder<int>(
        valueListenable: _bottomNavNotifier,
        builder: (_, int currentIndex, __) {
          return BottomNavigationBar(
            items: _bottomNavBarItems,
            currentIndex: currentIndex,
            onTap: _movePageTo,
          );
        },
      ),
    );
  }
}

If the error logs do not appear, try quickly move to the next or previous page after scrolling vertically

danagbemava-nc · 2021-09-14T13:15:10Z

@iandis, do you use the gesture-based/scroll wheel scrolling or click-drag scrolling?

iandis · 2021-09-14T19:32:07Z

@danagbemava-nc it was scroll-wheel scrolling, running on desktop mode web, not the mobile mode one.

danagbemava-nc · 2021-09-15T07:16:51Z

Hi @iandis, thanks for filing the issue.

I could not reproduce it with Curves.fastLinearToSlowEaseIn, but after changing to Curves.easeIn I was able to reproduce it.

Tested on macOS and web, issue is reproducible on both master and stable. It's possible it affects all desktop platforms but this does not reproduce on android or iOS with the sample code provided.

The error message does however provide a clear way to solve the issue.

Regardless, I will label it for visibility.

updated code sample

Hi there! It looks like you are having scrollbar issues on desktop (+ web running on desktop).

This is because Scrollbars are automatically applied to ScrollViews on desktop platforms by the ScrollBehavior.
In this case, there are two vertical ScrollViews. By default, when not provided a ScrollController, all vertical ScrollViews attach to the PrimaryScrollController. Likewise, when not provided a unique ScrollController, the Scrollbar will look to the PrimaryScrollController for information about the ScrollView/Position it is associated with. When the Scrollbar does this here, it finds more than one ScrollPosition. A Scrollbar can only represent one ScrollView at a time, so it results in an error.

I believe this is expected behavior. Providing a unique ScrollController to one or both of your ScrollViews should resolve your issue, or you can configure your ScrollBehavior as you like using the information in this guide.

iandis · 2021-09-23T17:21:49Z

Hi thank you for the clarification. I think it's clear now that when I provide ScrollControllers to the ScrollViews, this error log does not appear.

But I think instead of throwing error from the Animation Library, it would be better to throw it from the ScrollView instead so people would not be confused of the error message and would be able to resolve it.

Piinks · 2021-09-23T18:25:56Z

Great! I am glad that resolved your issue. I think it is coming from the animation library because the OP is executing an animation on the ScrollView.

_pageController.animateToPage(
     index,
     duration: const Duration(milliseconds: 500),
     curve: Curves.fastLinearToSlowEaseIn,
 );

In that case the error message is accurate, and provides an explanation of what the issue is and how to resolve it. If there is something else we can add to the error message, please let us know. :)
Otherwise, we can close this issue.

iandis · 2021-09-24T07:01:56Z

I agree with you about the error message being accurate, however the stacktrace doesn't look helpful to users since it points at the Animation Library and not the problematic ScrollView. Other than that I think is okay.

@Piinks We now do know the error is from auto implemented scrollbar on desktop. So we need to assign a ScrollController to every TabBarView or PageView to bypass the error only, wasn't that so redundant and annoying?

I am still insist on that, the default behavior of TabView+ListView as tab, should works on all platforms.

Maybe, can flutter provide such a solution, optionally change the default controller from PrimaryScrollController to creating a new fallback ScrollController if not supplied. For example, we can set it in ScrollConfiguration.

Disable auto implementation of scrollbar is not a solution, just escape from the problem.

The triaged-desktop label is irrelevant if there is no team-desktop label or fyi-desktop label.
