Flutter - 在两个固定容器之间插入一个 Listview

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(
      backgroundColor: Colors.indigo[900],
      appBar: AppBar(
        backgroundColor: Colors.white,
        elevation: 0,
        automaticallyImplyLeading: false,
        leading: IconButton(
            icon: Icon(Icons.arrow_back_ios_rounded,
                color: Colors.red[400], size: 25.0),
            onPressed: () {
              uD.clearSearchList();
              Navigator.pushReplacementNamed(context, StudentHomeScreen.id);
            }),
        title: Text(

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.
