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，出现以下错误：

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'.

    在https://developer.android.com/studio/build/dependencies#duplicate_classes了解如何解决该问题。     程序类型已经存在：android.support.v4.app.INotificationSideChannel

在我看来，它们两个都使用同一类android.support.v4.app.INotificationSideChannel，因为当我尝试仅使用它们中的一个时，一切都很好。但是我的应用程序都需要。如何忽略重复的类或只是解决这个问题？
