如何在Flutter中禁用开关选项卡 [英] How to disabled switch tab in flutter

问题描述

在我的帮助页面中，我具有此切换选项卡，但是我想知道如何禁用它，以便当用户单击单词"Trending"时，它不会执行任何操作.

In my help page, I have this switch tab but I'm wondering how can I disabled it so that when a user click on the word "Trending", it will not do anything.

我只想显示现在的方式，无论用户在哪里单击，但现在只要用户单击趋势"一词，选项卡就会切换.

I just want to display the way it's right now no matter where the user click but right now the tab got switch when ever a user click on the the word "trending".

对于我如何禁用它的任何帮助或建议，我们将不胜感激.

Any help or suggestion on how I can disabled it will be really appreciated.

 Widget tabBarWidget() {
    return Container(
      decoration: BoxDecoration(
          borderRadius: BorderRadius.circular(1),
          border: Border.all(color: Colors.grey, width: 1)),
      child: TabBar(
        controller: TabController(length: 2, vsync: this),
        tabs: [
          Tab(
            text: 'Recommended',
          ),
          Tab(
            text: 'Trending',
          )
        ],
      ),
    );
  }

推荐答案

尝试添加这种空函数调用或像这样的onTap为空

Try this adding empty function call or null onTap like this

Widget tabBarWidget() {
    return Container(
      decoration: BoxDecoration(
          borderRadius: BorderRadius.circular(1),
          border: Border.all(color: Colors.grey, width: 1)),
      child: TabBar(
        controller: TabController(length: 2, vsync: this),
        onTap:(i){}, // or onTap: null,
        tabs: [
          Tab(
            text: 'Recommended',
          ),
          Tab(
            text: 'Trending',
          )
        ],
      ),
    );
  }
