The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the incompatibility.

【问题讨论】：
试试answer 所说的内容。 【参考方案1】：删除android文件夹内的.gradle文件夹
在项目build.gradle文件中，升级你的类路径
例子： classpath 'com.android.tools.build:gradle:4.0.0'
转到android>gradle>gradle-wrapper.properties 文件并升级分发网址。
例子： distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.0-all.zip
使缓存无效并重新启动您的 android studio，它将下载新的 gradle 文件。
【讨论】：
【参考方案2】：通常，androidResourceLinkingFailed 错误通过清除缓存来解决。
如果您使用的是 Android Studio，请转到 File > Invalidate Caches / Restart 并重新启动您的 IDE，或在终端中运行此命令：flutter clean。
【讨论】：
我运行它并没有任何改变，但我会再次运行它以上是关于颤振：失败：构建失败并出现异常的主要内容，如果未能解决你的问题，请参考以下文章
