我在我的应用程序中使用flutter_smartlook进行监控。它工作正常，但升级到最新版本后4.1.7.运行时开始出错。如果我降级到4.1.5。它工作正常。有人知道出了什么问题吗？
为了使用最新的Flutter版本3.13.0，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：

刚刚得到了smartlook的支持回复。在这里张贴他们的回应：
“目前，我们的SDK中唯一可以与3.12.x版本的flutter一起使用的版本是预发布的https://pub.dev/packages/flutter_smartlook/versions/4.1.8-flutter3.13.0。请使用那个，你不应该面对这个问题，让我知道如果你有任何进一步的问题。

他们搞砸了一点与释放，现在一个新的版本4.18是出来，但它不支持flutter13，所以如果你定义你的依赖在清单与插入符号

flutter_smartlook: ^4.1.8-flutter3.13.0

它不会工作，你需要通过删除插入符号来坚持确切的版本：

flutter_smartlook: 4.1.8-flutter3.13.0

我希望他们能很快合并扑13的变化，主要分支，它已经出了几个月了。

dart 非抽象类“CustomCanvas”缺少这些成员的实现
