【问题描述】：

将 Flutter 从 1.9.7 升级到 v1.12.13+hotfix.5 后，我的应用程序构建失败。我遇到了以下异常：

[ +124 ms] > Task :draw:compileFossDebugSources UP-TO-DATE
[   +5 ms] > Task :draw:assembleFossDebug UP-TO-DATE

Gradle build failed to produce an .apk file. It's likely that this file was generated under C:\flutter_projects\my_branch\iamflexi_app\build, but the tool couldn't find it.

但是，当我在 Android Studio 中的 Android 模块中打开我的应用程序时，它运行良好，但是当我尝试使用 Flutter 运行时，出现了该错误。

【问题讨论】：

你已经升级到 gradle 6 与其他人不匹配。要查看已弃用的内容，请使用：***.com/questions/51610420/…

如果你愿意，你也可以降级 gradle 版本

distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-all.zip 这是我在 gradle-wrapper.properties 文件中的 gradle 版本，它在Flutter 1.9.7 版，但在我升级到 Flutter 1.12 版后，我收到了这个错误。

我不知道为什么，但看看：***.com/a/59453116/6658129

【参考方案1】：

使用 Android Studio 可能会提示您升级项目的设置（即 gradle 版本）。此问题的快速解决方法是降级到项目以前的 gradle 版本，如之前在 cmets 中提到的。您还可以尝试查看此 GitHub 问题线程 ahttps://github.com/flutter/flutter/issues/45681 上发布的建议，看看是否有任何适合您的方法。
