发行版Android中的Flutter中缺少MissingPluginException [英] MissingPluginException in flutter in release mode android

问题描述

当您尝试在发布模式下构建apk时，许多插件都无法正常工作，但是这些插件在调试模式下可以完美运行

Many plugins aren't working in flutter when you try to build a apk in release mode , but these plugins are working perfectly in debug mode

有人建议将gradle版本更改为3.5，但有时使用的插件可能与 file_picker_cross

Some recomend changing the gradle version to 3.5 , but sometimes the plugins used may not be compatible with the same like file_picker_cross

其他人在构建apk时建议使用-no-shrink 选项，即 flutter build apk --release --no-shrink

Others recomend using --no-shrink option while building the apk i.e flutter build apk --release --no-shrink

这些解决方案都不适合我，我发现这个解决方案埋在github问题对话中

None of that solutions worked for me , i found this solution burried in a github issue conversation

检查以下解决方案

推荐答案

最近扑朔迷离的proguard规则正在弹出未正确注册的插件

Looks like the recent proguard rules in flutter is ejecting the plugins which arent registering properly

在项目的 app/build.gradle

更改

buildTypes {
        release {
            signingConfig signingConfigs.release
        }
    }

到

buildTypes {
        release {
            shrinkResources false
            minifyEnabled false
            signingConfig signingConfigs.release
        }
    }

添加的额外两行似乎跳过了proguard规则部分，从而免除了您的噩梦，这只是暂时的解决方法，可能很快就会解决

The added extra 2 lines seems to skip the proguard rules part thereby saving your from the nightmare , this is just a temporary work around , there might be a fix soon from flutter

当然，这会跳过proguard优化，但现在至少可以使用该代码；)

Ofcourse this skips the proguard optimization , but atleast the code works now ;)

我一直在浪费时间将近6个小时，却不知道解决方案，所以我将其发布在这里给其他人

I have been wasting my time for almost 6 hours without knowing the solution ,so I am posting it here for others
