在我使用问题部分的--can标志后，出现了其他内容。

我从appbrewery颤振课程中获取了这个颤振应用程序的所有材料。这是在我尝试制作MIcard项目时发生的。有没有解决这个问题的想法？

Answer 1

我也遇到了同样的错误，我进一步尝试：

1. 颤振干净
2. flutter pub在终端中获取，问题解决了！

Answer 2

转到pubspec。yaml文件，尝试执行包get | Pub get，然后再次构建项目。

Answer 3

对我有用的是：删除你的pubspec。锁定，然后在您的pubspec中按“Pub Get”。yaml，它将重新生成pubspec。再次锁定文件，应该可以解决问题。
