This is an app I'm trying to create, I'm trying to add a button to get to the menu, but I don't know where to add it.

 @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Column(
        children: [
          Expanded(
              child: Container(
            color: Colors.black,
            child: Center(
                child: Stack(
              children: [
                Updown(
                  updownY: UpdownY,
                )
              ],
            )),
          ))
        ],
      ),
    );
  }
}

Hope someone with a good heart can guide me in this difficult matter.

It should be something like this assuming you use ElevatedButton

  @override
      Widget build(BuildContext context) {
        return Scaffold(
          body: Column(
            children: [
              Expanded(
                  child: Container(
                color: Colors.black,
                child: Center(
                    child: Stack(
                  children: [
                    Updown(
                      updownY: UpdownY,
                    ),
                GestureDetector(
            onLongPress: () => "Navigate",
            child: const Image(
              height: 60,
              image: AssetImage("assets/your_asset.jpg"),
            ),
          )
                  ],
                )),
              ))
            ],
          ),
        );
      }
    }

If you meant you want to show the AppBar menu, so you can try this:

Scaffold(
            appBar: AppBar(
              title: Text('My app'),
              centerTitle: true,
)

Or if you meant to add a normal button to the screen, so you can add many kinds of buttons (elevated - material - text - ...etc).

In general I use MaterialButton, it's simply to use it, like this:

MaterialButton(
              onPressed: () {},
              color: Colors.blueAccent,
              child: const Text('Test button'),
            ),
