【问题讨论】：

你做了flutter更新了吗？你有哪个版本的？ @Hakiza Flutter 版本 1.20.3，dart 版本 2.9.2，是的，我做了 Flutter 更新您找到解决方案了吗？如果是，请分享。 【参考方案1】：

Jimmy Anderson 运行flutter upgrade 后，您需要检查现有项目使用的dependencies 是否也是最新的。

version 1.20.1 出现同样的错误，解决方案是删除 Pods 文件夹，pubspec.lock 文件：

)：完全清除所有指向链接的点：

flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec

)：最后运行这些：

rm ios/Podfile
rm pubspec.lock
flutter run

如果有人有最新的答案，可以完成这个临时解决方案。

【参考方案2】：

这些步骤帮助我解决了类似问题

android

删除pubspec.lock文件 flutter clean（在你的项目目录中） flutter pub get flutter build apk --release

然后我看到我的 Android 构建失败，这是一些与依赖相关的问题，我修复了这些问题。然后重复上面的步骤1。之后我的Android构建成功了。

然后尝试按照以下步骤进行 iOS 构建删除了ios目录中的Pods文件夹删除了ios目录下的Podfile.lock文件 cd ios pod install pod update cd .. flutter clean flutter pub get flutter build ios --release

然后我的 iOS 构建成功了

【参考方案3】：

这些步骤对我有用：

flutter build

flutter build ios
