Unhandled Exception: Cannot get renderObject of inactive element

Hello there. I've found this amazing project when looking for an alternative to inview_notifier_list (it doesn't support ListView.builder) and It was working as expected but when I try to scroll up so fast it gives me this error.

[VERBOSE-2:ui_dart_state.cc(209)] Unhandled Exception: Cannot get renderObject of inactive element.
In order for an element to have a valid renderObject, it must be active, which means it is part of the tree.
Instead, this element is in the _ElementLifecycle.defunct state.
If you called this method from a State object, consider guarding it with State.mounted.
The findRenderObject() method was called for the following element:
  StatefulElement#081b1(DEFUNCT)
#0      Element.findRenderObject.<anonymous closure>
package:flutter/…/widgets/framework.dart:4006
#1      Element.findRenderObject
package:flutter/…/widgets/framework.dart:4019
#2      TrackerState._handleFirstRender
package:flutter_tracker_widget/src/tracker_state.dart:68
<asynchronous suspension>

Is this project still maintained? and if so, is there a fix to this issue?

In inview_notifier_list the same error would happen if I tried to scroll too fast but it looks like it was solved with this commit.

I don't know if the commit above is relevant, but I hope it gives an idea about how to solve this issue.

Thank you for your incredible work and Good Luck.
