Linked Scroll Controller error when use ListView, _LinkedScrollPosition cannot change controllers once created.

[anhlevfx]

Hello, I have problem when use linked_scroll_controller lib package

I create a stateless widget (A) include 3 list view and link them with LinkedScrollControllerGroup.
I put A in as item of parent list view (B).
Problem is when I scroll B, usually I got an error log below

_LinkedScrollPosition cannot change controllers once created.
'package:linked_scroll_controller/linked_scroll_controller.dart':
Failed assertion: line 139 pos 12: 'linkedPosition.owner == this'

I set key for each item of B but problem still happen randomly.

Please help me resolve this.

Check his implementation of the package here, maybe it'll answer your question:

You have to add a new UniqueKey() to each widget that has a linked controller.
