Flutter - Insert a Listview between two fixed containers - flutter

Question

This particular screen is composed of a large container (Height of screen) : This container is composed of three parts : A header (fixed container : 10% of screen size), a footer (fixed container : 10% of screen size) and a middle part : container : height of 80% of screen size.
I would like the middle container to be scrollable : so I inserted a LISTVIEW as the child of this container... but it keeps telling me I get a RenderFlex overflowed.... Why doesn't the content of the middle container scroll in between the header and the footer ??
Here is the code :
Scaffold(

Answer 1

You should replace the middle Container (the one with the 0.8 * MediaQuery height) with Expanded so it will take the available space between the 2 other Containers.
