问题是BottomNavigationBarItem中没有title属性,而是使用label

另外,第一张图片中的错误提示说label等于null

英文:

the problem is that there is no property title in the BottomNavigationBarItem, instead use label

also the error in the first picture says, that label is equal to null

底部导航栏项目中没有名为'title'的参数。您需要使用'label'来为BottomNavigationBarItem小部件提供文本,并直接使用字符串。

因此,更新后的代码将如下所示:

bottomNavigationBar: BottomNavigationBar(
  items: const <BottomNavigationBarItem>[
    BottomNavigationBarItem(
      icon: Icon(
        Icons.home,
      ),
      label: '首页',
    ),
    BottomNavigationBarItem(
      icon: Icon(
        Icons.message,
      ),
      label: '消息',
    ),
    BottomNavigationBarItem(
      icon: Icon(
        Icons.person,
      ),
      label: '个人资料',
    ),
  ],
)
英文:

Bro there's not parameter with name 'title' in the BottomNavigationBarItem. you need to use label for giving the text in the BottomNavigationBarItem widget and it aspects string directly.

So the updated code would look like this:

bottomNavigationBar: BottomNavigationBar(
    items: const &lt;BottomNavigationBarItem&gt;[
      BottomNavigationBarItem(
          icon: Icon(
            Icons.home,
          ),
          label: &#39;Home&#39;,
      ),
      BottomNavigationBarItem(
        icon: Icon(
          Icons.message,
        ),
        label: &#39;Messages&#39;,
      ),
      BottomNavigationBarItem(
        icon: Icon(
          Icons.person,
        ),
        label: &#39;Profile&#39;,
      ),
    ],
  ),

你应该使用"label"而不是"title"
