我在我的应用程序中使用 flutter_smartlook 进行监控。它工作正常，但升级到最新版本 4.1.7 后。运行时开始出现错误。如果我降级到4.1.5。一切正常。谁能知道出了什么问题吗？
为了使用最新的 Flutter 3.13.0 版本，我别无选择，只能将软件包升级到 4.1.7。或者我必须使用旧的 Flutter 版本 3.10.6
错误：
/Users/casperonflutter/.pub-cache/hosted/pub.dev/flutter_smartlook-4.1.7/lib/wireframe/element_descriptors/canvas_descriptor.dart:7:7: Error: The non-abstract class 'CustomCanvas' is

Try to either
- provide an implementation,
- inherit an implementation from a superclass or mixin,
- mark the class as abstract, or
- provide a 'noSuchMethod' implementation.
