在 VScode 中将依赖项添加到 gradle 后无法同步

Question

我尝试配置我的颤振项目以使用 firebase。在将firebase中提到的行添加到Gradle构建后，我添加了所有依赖项并且无法同步。 如何在 vscode 中同步。

增加了对 firebase 的依赖：

在项目中 -> android -> 应用程序 -> build.gradle ：

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

在项目中 -> gradle -> build.gradle：

 dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        **classpath 'com.google.gms:google-services:4.3.3'**
    }

IN 项目 -> pubspec.yaml

firebase_auth: ^0.14.0+5

还跑了flutter pub get

错误日志：

使用 Firebase 时，您需要下载 google-services.json 文件并将其添加到您的项目中：

Where do I place Googleservices.json in Flutter app in order to solve 'google-services.json is missing'

然后在android/build.gradle，需要添加google() maven仓库：

buildscript {
  repositories {
    // Check that you have the following line (if not, add it):
    google()  // Google's Maven repository
  }
  dependencies {
    ...
    // Add this line
    classpath 'com.google.gms:google-services:4.3.3'
  }
}

allprojects {
  ...
  repositories {
    // Check that you have the following line (if not, add it):
    google()  // Google's Maven repository
    ...
  }
}

在android\app\build.gradle里面，你需要添加google-service插件：

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