越来越cloud_firestore：0.9.0依赖关系打破了扑扑的应用程序

我已将cloud_firestore：^ 0.9.0程序包添加到新的flutter项目中，因此我创建了一个新的flutter项目，仅用于测试Firebase程序包。

并在“ package get”之后得到此错误，并启动了项目。

重建步骤：

1. 复制pubspec.yaml cloud_firestore的Firebase软件包版本：^ 0.9.0并将其添加到pubspect.yamel文件中。并获得包裹。
2. 在Firebase网站上创建帐户后，下载了google-services.json。

3. FLUTTERAPP / android / buld.grundle ive添加了这一行代码

   classpath'com.google.gms：google-services：4.2.0'

4. 最后我添加了FLUTTERAPP / android / app / build.grundle这样的代码

   应用插件：“ com.google.gms.google-services”

启动了应用程序。
