Question

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,
                        ^^^^^^^^^^^^

我的 flutter doctor 一切都很好，没有错误，我的 flutter sdk 是最新版本。我队友的应用程序在她身上运行良好。请帮忙

Answer 1

正如错误所说，您正在使用名为 ClipBehaviour 的变量您应该在哪里使用类 Clip 的变量（您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，而您没有）

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

就这样看看有没有帮助

这就是窍门。谢谢

  clipBehavior: Clip.none,

没有为“Stack”类定义 getter ClipBehavior
