android - 由于Firebase分析导致Gradle失败

Question

我按照说明将Android应用添加到Firebase项目中，但运行代码时出现以下错误:

FAILURE: Build failed with an exception.

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

我该如何解决？我只是从官方的Firebase文档中复制并粘贴，而我正在使用Flutter。
应用程序/build.gradle

apply plugin: 'com.google.gms.google-services'
dependencies {
    implementation 'com.google.firebase:firebase-analytics'
    ...
}

android / build.gradle

dependencies{
  classpath 'com.google.gms:google-services:4.3.4'
  ...
}

您需要为依赖项指定一个版本号。您可以在release notes中找到最新版本。

implementation 'com.google.firebase:firebase-analytics:17.5.0'

但是，由于您使用Flutter标记了此问题，因此，如果要构建Flutter应用程序，则可能应遵循 documentation中的说明。

To use this plugin, add firebase_analytics as a dependency in your pubspec.yaml file. You must also configure firebase analytics for each platform project: Android and iOS (see the example folder or https://codelabs.developers.google.com/codelabs/flutter-firebase/#6 for step by step details).

您可以在 Firebase documentation for Flutter中进一步阅读:

dependencies:
  firebase_analytics: ^5.0.2
