我正在尝试运行包含“堆栈”的应用程序，但它给了我一个错误：

/C:/flutter/.pub-cache/hosted/pub.dartlang.org/convex_bottom_bar-2.6.0/lib/src/stack.dart:43:25: Error: The getter 'ClipBehavior' isn't defined for the class 'Stack'.
 - 'Stack' is from 'package:convex_bottom_bar/src/stack.dart' ('/C:/flutter/.pub-cache/hosted/pub.dartlang.org/convex_bottom_bar-2.6.0/lib/src/stack.dart').
Try correcting the name to the name of an existing getter, or defining a getter or field named 'ClipBehavior'.
          clipBehavior: ClipBehavior,
                        ^^^^^^^^^^^^

【解决方案1】：

正如错误所说，您正在使用名为 ClipBehaviour 的变量你应该在哪里使用 Clip 类的变量（你朋友的代码可能正在工作，因为他在他的代码中定义了一个名为 ClipBehaviour 的变量，而你没有）

   Stack(
        clipBehavior: Clip.none,
        children: const <Widget>[
          SizedBox(
            width: 100.0,
            height: 100.0,
          ),
        ],
      );

就这样看看有没有帮助

【讨论】：

它不起作用，我们都有完全相同的代码。我添加了 (clipBehavior: Clip.none,) 但仍然是同样的问题。还有什么想法吗？
你有没有给你的其他类命名为 Clip？导致我认为发生这种情况的唯一其他原因是因为您已命名任何小部件或类 Clip 并且颤振认为您想要覆盖现有的 Clip 类并给您一个错误。这是我唯一能想到的。

【解决方案2】：

这就是诀窍。谢谢

  clipBehavior: Clip.none,
