The following assertion was thrown while applying parent data.:
**Incorrect use of ParentDataWidget.**
The ParentDataWidget Expanded(flex: 1) wants to apply ParentData of type FlexParentData to a RenderObject, which has been set up to accept ParentData of incompatible type ParentData.
Usually, this means that the Expanded widget has the wrong ancestor RenderObjectWidget. Typically, Expanded widgets are placed directly inside Flex widgets.
The offending Expanded is currently placed inside a RepaintBoundary widget.
Firstly, you dont need Expanded directly inside TabBarView that is wrapped with ListView.
Also the for the second tab item, seems you like to scroll without PhysicalModel. For the background I am using Stack here.
