android - flutter 错误无法确定任务 ':app:compileDebugJavaWithJavac'的依赖关系

Question

我只是创建了一个空应用程序，然后当我在模拟器上运行它时，发生了错误。

只有当我在 android 模拟器上运行时才会出现此错误，但 ios 工作正常。

现在我进入了 flutter beta channel 。

所以如果有人有任何想法，请告诉我。谢谢

这是错误日志

运行 Flutter Doctor，如果“android 许可证”部分有感叹号和警告颜色，请运行 flutter doctor --android-licenses。只要接受一切，就会幸福。这对我有用。
