我使用这两个包：
barcode_scan: ^0.0.3
fluttie: ^0.3.0
当我尝试运行我的应用程序时，我会得到以下错误：
D8: Program type already present: android.support.v4.app.INotificationSideChannel
FAILURE: Build failed with an exception.
* What went wrong:

在我看来，它们都使用相同的类android.support.v4.app.INotificationSideChannel，因为当我尝试只使用其中一个时，一切都很好。但我的申请表上需要这两个。我怎样才能忽略重复的类或只是解决这个问题？
我面临着与qr_code_scanner相同的冲突，解决方案是删除或更改其中一个的类。我不知道flutter是否有内置的方法来处理这种冲突。但是你可以尝试的是从git repo中获取包。这些更改将代码推送到你自己的repo中，并从你自己的git repo:中发布
