demo中NestedScrollView 必现error

操作步骤：1、向下滑动触发load more ，2、向上滑到头下拉触发刷新

════════ Exception caught by rendering library ═════════════════════════════════ The following assertion was thrown during performLayout(): RenderBox.size accessed beyond the scope of resize, layout, or permitted parent access. RenderBox can always access its own size, otherwise, the only object that is allowed to read RenderBox.size is its parent, if they have said they will. It you hit this assert trying to access a child's size, pass "parentUsesSize: true" to that child's layout(). 'package:flutter/src/rendering/box.dart': Failed assertion: line 2009 pos 13: 'debugDoingThisResize || debugDoingThisLayout || _computingThisDryLayout || (RenderObject.debugActiveLayout == parent && size._canBeUsedByParent)'

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
