This is what the debug console suggests:
The overflowing RenderFlex has an orientation of Axis.vertical. The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and black striped pattern. This is usually caused by the contents being too big for the RenderFlex. Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the RenderFlex to fit within the available space instead of being sized to their natural size. This is considered an error condition because it indicates that there is content that cannot be seen. If the content is legitimately bigger than the available space, consider clipping it with a ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex, like a ListView. The specific RenderFlex in question is: RenderFlex#33d4b relayoutBoundary=up2 OVERFLOWING: needs compositing creator: Column ← MediaQuery ← Padding ← SafeArea ← Stack ← LayoutBuilder ← SizedBox ← Center ← KeyedSubtree-[GlobalKey#bf933] ← _BodyBuilder ← MediaQuery ← LayoutId-[<_ScaffoldSlot.body>] ← ⋯ parentData: offset=Offset(0.0, 0.0) (can use size) constraints: BoxConstraints(0.0<=w<=500.0, 0.0<=h<=237.0) size: Size(500.0, 237.0) direction: vertical

And this on each text widget

How can I solve this issue?
Thanks for any help you can provide
CodePudding user response：
I think you can use bottomNavigationBar for adding that item. and use Column[HeaderWidget,Expanded(ListViwe)] or just body:ListView on Scaffold body .
You can play with decoration, It depends on your ux how you like to handle scroll event, you may like SliverAppBar on CustomScrolView
