我真的对Flutter感到沮丧：

C:\Users\User\dev\DIR\app-project\android\app\src\main\java\io\flutter\plugins\GeneratedPluginRegistrant.java:19: error: cannot find symbol
      flutterEngine.getPlugins().add(new com.amazonaws.amplify.amplify_analytics_pinpoint.AmplifyAnalyticsPinpointPlugin());
                                                                                         ^

我真的不知道为什么这个错误是弹出了几天以来，没有任何改变。我没有直接使用这个依赖项。已经试图从我的PC和项目以及完全删除Flutter。后来我安装flutter新鲜，也克隆了项目.
我也试过：

flutter clean
flutter pub cache repair
flutter pub get

有人能帮我吗？
