Flutter 升级到Android X后出现Firebase问题

失败：生成失败，出现异常

• 出了什么问题： 无法确定任务“：firebase_core:CompiledBugAIDL”的依赖项
  图书馆com.google.firebase:firebase iid正被其他各种图书馆在[[20.0.1,20.0.1]]请求，但解析为17.0.3。禁用插件并使用./gradlew:app:dependencies检查依赖关系树

• 尝试： 使用--stacktrace选项运行以获取堆栈跟踪。使用--info或--debug选项运行以获得更多日志输出。使用--scan运行以获得完整的洞察力

• 得到更多的帮助

在4s中生成失败 已完成，但出现错误：Gradle任务assembleDebug失败，退出代码为1
