android - 错误: package androidx.生命周期在flutter中不存在

Question

我想在flutter中使用local_auth插件，它需要Android生命周期，所以我安装了flutter_plugin_android_lifecycle，但是如果我尝试发布apk会出现这个错误:错误:
包 androidx.lifecycle 不存在。我尝试了很多东西，但我就是无法让它工作。

Answer 1

在 build.grable 插件文件夹中添加实现 'androidx.lifecycle:lifecycle-extensions:2.2.0' 将解决该问题。
