设置 firebase 时出现错误

Question

当我将 firebase 连接到 android studio 上的 flutter 项目时，我收到此错误，我已经完成了他们在 firebase 安装部分中提到的所有设置

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'android'.
> Could not resolve all files for configuration ':classpath'.
   > Cannot resolve external dependency com.google.gms:google-services:4.4.1 because no repositories are defined.

Answer 1

这是因为，buildscript{} 中没有存储库列表。

您可以通过从 allprojects{} 复制存储库列表并将其粘贴到 buildscript{} 中来解决此问题。

以下是解决此问题的方法，

buildscript {
  repositories {
    google()
    mavenCentral()
  }
  dependencies {
    classpath 'com.google.gms:google-services:4.4.1'
  }
}

allprojects {
  repositories {
    google()
    mavenCentral()
  }
}
