[two_dimensional_scrollables] TableView crashes when scrolling too fast with mousewheel

Steps to reproduce

For my Flutter project i switched recently to two_dimmensional_scrollables and ditched my solution wih two scrollviews. The performance with this Widget is much better due to lazy loading.

Around the TableView.builder() Widget is use a ScrollConfiguration with a CustomScollbehaviour as parent to be able to scroll by dragging with mouse instead only to drag with touch.

I divided my TableView into smaller pieces to make use of the lazy loading.

Now i have the problem, that when scrolling fast enough with a mousewheel, due to faster scrollspeed or by showing more elements at the same time and scrolling slightly slower, the widget crashes and start to disappear when i continue scrolling. I get the following errors. Even a hot restart of the application doesn't recover the programm. I have to stop and restart the programm from scratch.

The problem does not appear when scrolling with any device using drag and drop, even for mouse Inputs.

What i tried:

I tried to invstigate the problem. The problem appears especially on devices with lower compute power. It also get worse, when the small pieces of the TableView need some calculation to build. I made the problem less worse by caching the already build widgets instead of rebuilding them when returning to an already visited spot in the Tableview.

Problem appears on the following Platforms: Web, Windows, Linux. For Android the problem not yet appeared, because there we were scrolling by touch and not with a mousewheel.

We were now at the current latest Version 0.2.1 with Flutter 3.19.5

Expected results

The TableView shouldnt crash when scrolling with MouseWheel

Actual results

The widgets crashes and starts to disappear when scrolling further.

Code sample

Call of the TableView Widget

ScrollConfiguration(
  behavior: MyCustomScrollBehavior(),
  child: TableView.builder(
      horizontalDetails: ScrollableDetails.horizontal(
        controller: horizontalScrollController,
        physics: BouncingScrollPhysics(),
      ),
      diagonalDragBehavior: diagonalDragBehavior,
      verticalDetails: ScrollableDetails.vertical(
          controller: _verticalController,
          physics: const AlwaysScrollableScrollPhysics(),
      ),
      cellBuilder: _buildCell,
      columnCount: Conf.timeToDisplay+1,
      columnBuilder: _buildColumnSpan,
      rowCount: numberOfRows,
      rowBuilder: _buildRowSpan,
      pinnedRowCount: (filterList.isNotEmpty)?2:1,
      pinnedColumnCount: 1,
  ),
);

Custom Scrollbehaviour:

class MyCustomScrollBehavior extends MaterialScrollBehavior {
  @override
  Set<PointerDeviceKind> get dragDevices => {
    PointerDeviceKind.touch,
    //PointerDeviceKind.invertedStylus,
    //PointerDeviceKind.stylus,
    PointerDeviceKind.mouse,
    PointerDeviceKind.trackpad,
    // etc.
  };
  ScrollPhysics get physics => AlwaysScrollableScrollPhysics();
}

A similar issue was fixed recently #141101 which should be available on master, so please switch to master, upgrade it and run your scenario again to confirm.

flutter channel master
flutter upgrade

@darshankawar

@darshankawar
Thank you for the fast response. I upgraded like mentioned. I'm now on Flutter (Channel master, 3.22.0-16.0.pre.57). It is now a bit harder to reproduce the error (faster scrolling and/or displaying more elements neccessary) but the error continue to happen. But now i get a new error message. Still no recovery with Hot Restart, only a complete new rebuild of the app help. Checked on this platforms and mods:

Linux, debug mode -> crashes
Linux, release mode -> crashes
Chrome, debug mode -> not crashing (but scrolling too slow to test it)
Chrome, release mode -> crashes

Windows version yet to Test.
Edit:
Windows, debug mode -> crashes
Windows, release mode -> crashes

@yahooooza

Thanks for the update @yahooooza
Can you provide us complete runnable reproducible code sample (ex: main.dart)?

@darshankawar

Appearently i cant provide code in a single file because of many dependencies. I will work on a strestest for this widget that i can share that should make the bad behaviour visible. Next week i'm on vacation, so this will take a bit. I will get back to you later. Thx @darshankawar

@darshankawar

Hi @darshankawar,

i build a stresstest that catches the principle of my projects two dimmensional scollable. Unfortunatley, i am not able to reproduce the error i get with my Project. Here is the stresstest in a main.dart file. This stresstest does not contains extra dependencies like riverpod or freezed that i use in my project.

stresstest.zip

During testing i found out, that i get different types of error messages at once. The messages are so large, that my terminal are not able to keep them all in storage. Here are three types of additional errors i was able to catch. I hope that helps.
