【中文标题】在 Flutter 2 和 XCode 12.5 更新后发生的 Flutter unknown iOS 构建中的错误

【英文标题】：Error in Flutter unknown Error in iOS build, occurred after Flutter 2 and XCode 12.5 update

【发布时间】：2021-06-11 11:09:37

【问题描述】：

我的应用程序一直在运行，并且将在 android 和 ios 上发布，但几天前在我更新到 Flutter 2.0 和 XCode 12.5 后，“flutter run”仅在 iOS 中失败。 我将 XCode 降级到 12.4 仍然无法正常工作。

【问题讨论】：

我认为您需要更新 ios 文件夹中的 AppFramework.plist 部署目标。我以前遇到过这个问题。 Podspec 文件应该被删除并使用flutter clean。 Pod repo update 然后确保您更新了 AppFramework.plist 和 Info.plist 上的部署目标。它应该可以工作。

我用最新的 Flutter 和 xcode 重新创建了项目，我尝试删除 podfile、pods 并使用 pod init、安装、更新多次无效，用 podfile 更新了问题

已解决，包升级和项目中要更新的新包配置

【参考方案1】：

运行对我有用的 pod update 有需要更新的包。 同样的事情发生了我的应用程序没有构建我运行 flutter clean 然后 flutter pub get 然后 pod update 为我解决了它。

【讨论】：

试过不行，尝试了所有基本的东西，更新pod，检查证书，从头开始创建新项目

lib/widgets/PdfRender.dart:14:8 what is the code error at this line

我认为这与第二行错误无关，不断变化，未能构建应用程序导致继续错误

【参考方案2】：

我的 pod 文件看起来像这样并且完美运行
