Android MissingPluginException（在channel plugins.flatter.io/shared_preferences上找不到方法getAll的实现）-现有解决方案没有'；行不通-

我正在构建一个使用这些包的应用程序

• firebase_核心：^0.5.0
• firebase_分析：^5.0.16
• 云存储：
• firebase_消息：^7.0.0
• 颤振本地通知：^1.4.4+2
• 提供程序：^4.3.1
• http:^0.12.2
• 查看\u滑块：^1.0.5
• 颤振屏幕util:^2.3.0
• 共享的首选项：^0.5.12
• 滚动到索引：^1.0.6
• firebase_数据库：^4.0.0
• 图像选取器：^0.6.7+11
• 获取：^3.11.1

在调试模式下，一切都很正常，但是当我构建一个版本时，我得到了一个错误，我已经搜索了3天，所有我发现你需要的

flutter clean
pub get/ pub upgrade

尝试将get\u it版本降级为： 获取它：^3.0.3 然后在命令窗口中写入： 扑通

问题是缩小应用程序删除了一些重要代码，因此必须在proguard文件中解决它，因此我在proguard文件的底部添加了这一行

-keepclasseswithmembers class * {*;}

因此，它保留了所有类和函数，而不删除任何代码

这对我很有帮助
