flutter报错，tabbarview 嵌套listview

因为布局比较复杂，并不是单纯的简单嵌套，所以暂时未找到解决办法，解决中

======== Exception caught by rendering library =====================================================
The following assertion was thrown during performLayout():
RenderCustomMultiChildLayoutBox object was given an infinite size during layout.

This probably means that it is a render object that tries to be as big as possible, but it was put inside another render object that allows its children to pick their own size.
The nearest ancestor providing an unbounded height constraint is: RenderIndexedSemantics#0efe1 relayoutBoundary=up37 NEEDS-LAYOUT
...  needs compositing
...  parentData: index=0; keepAlive; layoutOffset=0.0 (can use size)
...  constraints: BoxConstraints(w=360.0, 0.0<=h<=Infinity)
...  semantic boundary
...  size: Size(360.0, 20.0)
...  index: 0
The constraints that applied to the RenderCustomMultiChildLayoutBox were: BoxConstraints(w=360.0, 0.0<=h<=Infinity)
The exact size it was given was: Size(360.0, Infinity)

See /docs/development/ui/layout/box-constraints for more information.

The relevant error-causing widget was: 
  Scaffold file:///Users/rainsonking/AndroidStudioProjects/app_kw_plat/lib/components/list/kw_list_label.dart:114:20
