ScrollController attached to multiple scroll views

I don't have easy steps to reproduce this, sorry. The error message said to file an issue so here I am.

════════ Exception caught by gesture ═══════════════════════════════════════════
The following assertion was thrown while handling a gesture:
ScrollController attached to multiple scroll views.
'package:flutter/src/widgets/scroll_controller.dart':
Failed assertion: line 109 pos 12: '_positions.length == 1'

2

Either the assertion indicates an error in the framework itself, or we should provide substantially more information in this error message to help you determine and fix the underlying cause.
In either case, please report this assertion by filing a bug on GitHub:
  https://github.com/flutter/flutter/issues/new?template=2_bug.md

When the exception was thrown, this was the stack
#2      ScrollController.position
package:flutter/…/widgets/scroll_controller.dart:109
#3      ScrollController.offset
package:flutter/…/widgets/scroll_controller.dart:116
#4      _ReorderableListContentState._scrollTo
package:reorderableitemsview/reorderableitemsview.dart:331
#5      _ReorderableListContentState._wrap.<anonymous closure>.<anonymous closure>
package:reorderableitemsview/reorderableitemsview.dart:631
#6      _DragTargetState.didEnter
package:flutter/…/widgets/drag_target.dart:693
...
Handler: "onStart"
Recognizer: DelayedMultiDragGestureRecognizer#c450e
════════════════════════════════════════════════════════════════════════════════

I'm using reorderableitemsview: ^1.0.0, which is where the exception in question is being thrown from.

I do not manually create any scrollcontrollers, resolutions found https://stackoverflow.com/questions/52484710/flutter-scrollcontroller-attached-to-multiple-scroll-views don't apply

reorderableitemsview is a 3rd party plugin, please open an issue in the dedicated github
or provide your flutter doctor -v, your flutter run -v
and a minimal reproducible code sample without 3rd party plugins

I understand that reorderableitemsview is a third party plugin, and I understand that it's frustrating not having a minimal code sample.

I'd like to make clear that I'm not asking for help -- I'm just doing what the flutter error message specifically told me to do.

Here's flutter doctor -v and flutter run -v

flutter run -v (only up to where it started printing my own application code, since nothing interesting or from the flutter framework happened after that)

Hi @0xNF
Can you please provide a minimal complete reproducible code sample and its flutter run -v logs without using third part packages?
Thank you
