flutter gradle 异常退出（firebase 身份验证）

Question

我正在尝试使用我的颤振应用进行 Firebase 身份验证。

• 在 firebase 上注册了我的应用。
• 将 googleservices.json 复制到应用目录中。
• 按照 Firebase 的指示复制依赖项。

尝试在代码之前测试我的应用程序（在通过 USB 连接的我的 android 手机上），并显示以下错误：

壳牌：

Answer 1

我认为问题出在谷歌服务版本中。只需将其替换为

com.google.gms:google-services:4.2.0

在build.grade项目级别再试试。
