我使用这两个软件包：

barcode_scan: ^0.0.3
fluttie: ^0.3.0

当我尝试运行我的应用程序时，我收到以下错误：

D8: Program type already present: android.support.v4.app.INotificationSideChannel

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.

https://developer.android.com/studio/build/dependencies#duplicate_classes. Program type already present: android.support.v4.app.INotificationSideChannel

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。但我的应用程序需要两个。我如何忽略重复的类或只解决这个问题呢？
