【问题描述】：
我试图解决这个问题，但它总是给我同样的错误。
我使用以下 Firebase 服务：
- Firebase 身份验证
- Firebase 数据库
- Firebase 存储
- Firebase 消息传递
我希望能解决这个问题，感谢任何帮助，谢谢。

我更新了 Android -> build.gradle 上的版本。但现在又出现了另一个错误。

【问题讨论】：
-
您使用的是最新版本吗？
-
你的意思是java版本？
-
库版本。它们需要保持最新状态。
-
我已经更新了 Dart 和 Flutter 版本。但是从java我不知道我是否将它更新到最新版本，我在哪里可以查看它？
-
@DomingoMG 我绝不是 Gradle 专家（也只是想解决这个问题）。我去了
android/gradle/wrapper/gradle-wrapper-properties并将第6行从distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip更改为distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip，它似乎正在工作。你能尝试和建议吗？
