A RenderCustomMultiChildLayoutBox expected a child of type RenderBox but received a child of type RenderSliverStickyHeader.

I use this library has this error

A RenderCustomMultiChildLayoutBox expected a child of type RenderBox but received a child of type RenderSliverStickyHeader.

RenderObjects expect specific types of children because they coordinate with their children during layout and paint. For example, a RenderSliver cannot be the child of a RenderBox because a RenderSliver does not understand the RenderBox layout protocol.
The RenderCustomMultiChildLayoutBox that expected a RenderBox child was created by: CustomMultiChildLayout ← AnimatedBuilder ← DefaultTextStyle ← AnimatedDefaultTextStyle ← _InkFeatures-[GlobalKey#ba9f9 ink renderer] ← NotificationListener ← PhysicalModel ← AnimatedPhysicalModel ← Material ← PrimaryScrollController ← _ScaffoldScope ← Scaffold ← ⋯
The RenderSliverStickyHeader that did not match the expected child type was created by: SliverStickyHeader ← _BodyBuilder ← MediaQuery ← LayoutId-[<_ScaffoldSlot.body>] ← CustomMultiChildLayout ← AnimatedBuilder ← DefaultTextStyle ← AnimatedDefaultTextStyle ← _InkFeatures-[GlobalKey#ba9f9 ink renderer] ← NotificationListener ← PhysicalModel ← AnimatedPhysicalModel ← ⋯
The relevant error-causing widget was:
Scaffold file:///home/dev_03/flutter-app/test_header/lib/main.dart:69:12
When the exception was thrown, this was the stack:
#0 ContainerRenderObjectMixin.debugValidateChild. (package:flutter/src/rendering/object.dart:2993:9)

You cannot use a Sliver in a CustomMultiChildLayout. This package is only intended to be used in a scroll view (like CustomScrollView).
