任务'：app：processDebugResources'的Flutter Execution失败

Question

当Flutter beta v1.0.0出局时，我离开了我的扑动项目一段时间。现在我将我的项目移动到一个带有最新Flutter（稳定版v1.2.1）和Dart的新系统，并遇到了这个构建异常问题。

请注意，此项目在我的旧桌面扑动医生输出正常工作

由于我很久以后回来了，我不知道Flutter经历了什么变化，任何人都可以帮助我

颤振的输出在当前系统上运行

缺少的资源仅在API 28中添加。您需要将compileSDKversio文件中的build.gradlen更新为版本28。
