Flutter Error：java.lang.NoSuchFieldError PREFER_HIGHEST_OR_REMOTE_VERSION_NO_FORCE_STAGING

分类：Flutter作者：编程之家原文地址

我试图解决这个问题,但它一直给我同样的错误.

我使用以下firebase服务：

> Firebase Auth
> 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.

我在Android上更新了版本 – >的build.gradle.但现在又出现了另一个错误.

BUILD FAILED in 54s

Finished with error: Please review your Gradle project setup in the android/ folder.

解决方法:

我相信这是因为Google的一半FlutterFire插件使用的是旧版本的Android版本.因此,我已经指定了在我的应用程序级build.gradle中使用的版本.这可能不是一个永久的解决方案,但似乎已经在同一时间停止了崩溃.

在app level build.gradle中,将以下内容添加到依赖项：

implementation 'com.google.firebase:firebase-core:16.0.4'
implementation 'com.google.firebase:firebase-analytics:16.0.4'
implementation 'com.google.firebase:firebase-auth:16.0.4'
implementation 'com.google.firebase:firebase-firestore:17.1.1'
implementation 'com.google.firebase:firebase-functions:16.1.1'
implementation 'com.google.firebase:firebase-messaging:17.3.3'
implementation 'com.google.firebase:firebase-storage:16.0.3'

让我知道这个是否奏效.

编辑：仅添加您正在使用的Firebase插件的实现行.您可以找到每个here的最新版本.
