Опущность слоя ранее использовалась в качестве Oldlayer. Flutter Carousel_slider ⇐ Android

[Anonymous]

Я использую библиотеку Carousel_slider в своем приложении Flutter, и если я скрипят свой экран до конца и, если прокрутите вернуться к вершине, где присутствует мой виджет трепета ══╡ EXCEPTION CAUGHT BY SCHEDULER LIBRARY ╞═════════════════════════════════════════════════════════
The following assertion was thrown during a scheduler callback:
Layer OpacityEngineLayer was previously used as oldLayer.
Once a layer is used as oldLayer, it may not be used again. Instead, after calling one of the
SceneBuilder.push* methods and passing an oldLayer to it, use the layer returned by the method as
oldLayer in subsequent frames.
'dart:ui/compositing.dart':
Failed assertion: line 88 pos 9: ''

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:
