我在Flatter中的firebase存储依赖性中有一个问题我有另一个与firebase配合良好的项目，但我不知道为什么会出现此问题，我搜索了解决方案，但没有结果。当我尝试构建应用程序时，任何人都能帮上忙。它会给我以下错误：`构建失败，出现异常。

What went wrong:
A problem occurred configuring project ':firebase_storage'.

* Could not load compiled classes for build file 'C:\src\flutter\.pub-cache\hosted\pub.dartlang.org\firebase_storage-10.0.1\android\build.gradle' from cache.
* Failed to notify project evaluation listener.

   * Could not get unknown property 'android' for project ':firebase_storage' of type org.gradle.api.Project.
   * Could not find method implementation() for arguments [project ':firebase_core'] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.`
