Try to give listview properties shrinkWrap: true and try with expanded or without expanded

You could use CustomScrollView slightly differently to achieve that:

CustomScrollView(
      slivers: [
        SliverFillRemaining(
          hasScrollBody: true,
          child: ListView.builder(
            itemBuilder: (context, index) {
              return Text("${index}");
            },
            itemCount: 5,
          ),
        )
      ],
    )

You should use SliverList inside CustomScrollView.

CustomScrollView(
  slivers: [
    SliverList(
        delegate: SliverChildBuilderDelegate(
      childCount: 5,
      (context, index) {
        return Text("${index}");
      },
    )),
  ],
),
