flutter多个可滚动widget嵌套使用报错问题:Viewports expand in the scrolling direction to fill their container
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#6af77 relayoutBoundary=up3 NEEDS-LAYOUT NEEDS-PAINT
creator: IndexedSemantics ← NotificationListener<KeepAliveNotification> ← KeepAlive ←
AutomaticKeepAlive ← SliverList ← MediaQuery ← SliverPadding ← Viewport ← _ScrollableScope ←
IgnorePointer-[GlobalKey#20f10] ← Semantics ← Listener ← ⋯
parentData: index=0; layoutOffset=0.0 (can use size)
constraints: BoxConstraints(w=360.0, 0.0<=h<=Infinity)
semantic boundary
size: MISSING
index: 0
一开始是listview嵌套listview,我以为是类似Android里面那样,高度问题导致子view不显示,通过转换Column、Container…都不显示,但是我单独拿出来不放在listview中,能正常显示-------这是所暴露的问题,历时好一会之后;
listview里面包含的是Widget,并不是Scaffold; 所以子布局不能外围应用Container
在你引入的子布局模块时,要注意该模块return的是什么,对比下面
如下图 Colusm 里面 包含多个自定义的垂直布局
