Dismissible animation resets when listView is being rebuilt

[remi-martin]

Is there an existing issue for this?

• I have searched the existing issues
• I have read the guide to filing a bug

Steps to reproduce

1. Dismiss an item.
2. Drag to dismiss a second item while the first one is still animating.
3. When the first item is removed from the list, the drag position of the second item is reset.

Expected results

The dismissible widget should keep it's current state when another is successfully dismissed:

• Drag position.
• Waiting for onConfirm function.
• Resize animation.

Actual results

When the first item is removed from the list, the drag position and the resize animation of the second item are reset.

Code sample

Code sample

Since this issue can be reproduce in the official Dart pad.

Don't forget to call setState(() {}) to rebuild the list.

List<int> items = List<int>.generate(100, (int index) => index);

@override
Widget build(BuildContext context) {
  return ListView.builder(
    itemCount: items.length,
    padding: const EdgeInsets.symmetric(vertical: 16),
    itemBuilder: (BuildContext context, int index) {
      return Dismissible(
        background: Container(
          color: Colors.green,
        ),
        key: ValueKey<int>(items[index]),
        onDismissed: (DismissDirection direction) {
          setState(() {
            items.removeAt(index);
          });
        },
        child: ListTile(
          title: Text(
            'Item ${items[index]}',
          ),
        ),
      );
    },
  );
}

Hi @remi-martin Thanks for filing this issue. This might be a similar issue to a currently open issue #130211. Can you check this out to confirm it is?

[remi-martin]

Yes, it's the same issue, I struggled to find similar issues and only found ones without the list rebuild.
