添加firebase依赖项时渐变生成失败

我想在我的应用程序中使用Firebase，但每当我添加特定于Firebase的依赖项（例如：“cloud\u firestore:”或“Firebase\u analytics:^0.3.3”）时，我都无法构建该应用程序。当我进行颤振运行时，我收到以下输出：

因为如果您想在Android上运行Firebase，您需要添加Android依赖项

在

build.gradle

项目级文件中，您需要添加：

dependencies {
  // other dependencies might already be here

  classpath 'com.google.gms:google-services:3.1.2'
}

对于你的应用程序级别

build.gradle

，在最底部添加：

并非每个Dart的Firebase插件页面都有此信息，它展示了如何与Android和iOS集成

---

另外，在使用Android时，确保您的设备安装了Google Play services。

我已经这样做了，此外，在设置firebase Android项目时，我添加了以下说明：将'com.Google.firebase:firebase core:16.0.0'编译到应用程序级build.gradle文件中，当删除/注释掉它时，它似乎解决了问题。@Marko那么，我所说的是适用的，而你只是添加了太多？问题显然有点更深，我的修复不是真正的修复，这段视频很好地涵盖了它：

apply plugin: 'com.google.gms.google-services'
