使用 qrscan 和 flutter_facebook_auth 在 flutter 应用程序中重复依赖项

问题描述

是的，我知道这听起来很少见，但是当 gradle 运行时，会在任务 ':app:checkDebugDuplicateClasses' 和 'com.google.zxing.*' 中给出重复依赖项。显然，一个 Flutter 包使用 com.github.leyan95:android-zxingLibrary:0.1.2-PRE，另一个使用 com.google.zxing:core:3.3.3，并且两者都有 com.google.zxing.BarcodeFormat 类。

输出如下：

FAILURE: Build Failed with an exception.

* What went wrong:

关于从哪里开始寻找解决方案的任何想法？

解决方法

我找到了解决方案，我唯一需要做的就是在gradle中添加下一行

configurations.all {
    exclude group: 'com.google.zxing',module: 'core'
}

希望解决方案可以帮助其他人。
