Flutter--Android resource linking failed报错解决

一个依赖引发的崩溃啊……
我其实啥都没干，之前一直运行的好好的，这是在flutter中新加了一个插件，然后程序就炸了……

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugResources'.
> Android resource linking failed
  error: resource style/Theme.AppCompat.DayNight.Dialog (aka com.softfoxapp.soft_fox_app:style/Theme.AppCompat.DayNight.Dialog) not found.
  error: failed linking references.


* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

原因是缺少依赖……，那为什么之前也没有就可以呢？

解决办法：
在Android的build.gradle中添加：

    implementation 'androidx.appcompat:appcompat:1.0.0-alpha1'
