How can I disabled flutter switch

Question

In my help screen, I have this switch and the purpose for that is to do nothing but just display like the way it is.

But the problem I'm having right now, even though it doesn't do anything, the user can drag the switch so I'm trying to figure out how I can disabled it so that no one can drag the switch button.

    return Container(
      child: Card(
        color: Theme.of(context).primaryColor,
        margin: EdgeInsets.only(bottom: 30, top: 10),
        child: ListTile(
          title: Row(
            mainAxisAlignment: MainAxisAlignment.spaceBetween,
            children: <Widget>[
              Text("Dark Theme",
                  style: TextStyle(color: Theme.of(context).accentColor)),
              Switch(
                  value: true,
                  onChanged: (value) {},
                  activeColor: Theme.of(context).accentColor),
              Text("Light Theme", style: TextStyle())
            ],
          ),
        ),
      ),
    );
  }

To disable your Switch, edit its onChanged method to null like this

Switch(
  onChanged: null,
  value: true,
  inactiveThumbColor: Colors.tealAccent,
  inactiveTrackColor: Colors.tealAccent.withOpacity(0.5),
  // ...
),
