【问题讨论】：

animation 参数被github.com/flutter/flutter/pull/50180 拆分和重命名。因为显然没有使用 CupertinoFullscreenDialogTransition 的现有测试，所以该更改不会破坏任何测试，也不被视为破坏性更改。
@jamesdlin，好的，我期待相同的 - 但是如何在我不知道的拉取请求中找到此类信息。如何解决这个问题的一个问题？我应该怎么做？
从Error: No named parameter with the name 'animation'. 错误消息中，很明显CupertinoFullscreenDialogTransition 构造函数参数发生了变化。从那里我搜索了 flutter git 存储库以查找实现 CupertinoFullscreenDialogTransition 的位置，运行 git blame 以查看哪些提交修改了参数，并查看了其提交描述以找到引用的拉取请求。
你能告诉我们你在项目的 pubspec.yaml 文件中使用了哪些包/插件
我遇到了同样的问题，这修复了我的项目：See

【解决方案1】：

您需要检查构造函数上设置的参数名称，如错误中所述：Found this candidate, but the arguments don't match. CupertinoFullscreenDialogTransition

错误指向这个参数：Error: No named parameter with the name 'animation'.

检查 docs 的 CupertinoFullscreenDialogTransition，构造函数需要 primaryRouteAnimation 和 secondaryRouteAnimation。
