如何禁用颤振开关 [英] How can I disabled flutter switch

问题描述

在我的帮助屏幕中，我有此开关，其目的是不做任何事情，而只是按原样显示.

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.

但是我现在遇到的问题是，尽管它什么也没做，但是用户可以拖动开关，所以我试图弄清楚如何禁用它，这样没人可以拖动开关按钮

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())
            ],
          ),
        ),
      ),
    );
  }

推荐答案

要禁用您的 Switch ，请将其 onChanged 方法编辑为null

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),
  // ...
),
