use a column with 2 parts, title as a textbutton and above the list

Container(
                child: Column(
              children: [
                TextButton(
                  onPressed: () {
                    hideList = !hideList;
                  },
                  child: Text("Title"),
                ),
                hideList ? ListView() : Container(),
              ],
            ))

something like this

In order to add a Text widget above a list, both widgets should be inside a column and important thing to note is that ListView widget must be inside a Expanded widget and for the text widget to be clickable, use GestureDetector.

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(),
      body: Container(
        padding: const EdgeInsets.all(16),
        child: Column(
          children: [
            GestureDetector(
                onTap: () {}, child: const Text("Some text above the list")),
            Expanded(
              child: ListView.builder(
                itemCount: 50,
                itemBuilder: (context, i) {
                  return Container(
                      margin: const EdgeInsets.all(16),
                      color: Colors.pinkAccent,
                      child: Text("$i"));
                },
              ),
            ),
          ],
        ),
      ),
    );
  }
