无法确定任务 ':firebase_core:compileDebugAidl' 的依赖关系

Question

我正在使用 flutter 为 IOS 和 Android 构建应用程序。 刚刚添加了在 IOS 上完美运行的 Firebase_Auth 功能。 但是，当我尝试在 Android 模拟器上运行该应用程序时，我收到以下错误：

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':firebase_core:compileDebugAidl'.
> Could not resolve all task dependencies for configuration ':firebase_core:debugCompileClasspath'.
   > Could not find com.google.firebase:firebase-common:.
     Required by:
         project :firebase_core

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

此 GitHub 问题展示了解决方案。

更新android/app/build.gradle中的 Firebase SDK 对我有用：

rootProject.ext {
  set('FlutterFire', [
    FirebaseSDKVersion: '26.3.0'
  ])
}
