请注意flutter build ios 可以完美运行，没有任何警告或错误。

但是当我这样做时flutter build ios --obfuscate --split-debug-info=/_app/obfuscate

因为这个错误而失败：

我从 *** 收到一个错误，因此无法在不截断警告的情况下提交，因此我在中间将其切断。如果您需要更多这些警告，请询问我，我会将其发送给您..

我在这里缺少什么？即使在发布模式下，该应用程序也能正常工作。只有当我添加--obfuscate 标志时，它是这样的。

【参考方案1】：

最后我解决了这个问题。但是解决方案很乏味，我不确定这是否是最好的解决方案。但我认为这是稳健的解决方案：

flutter clean

然后它起作用了……至少对我来说。

还有其他解决方案吗？

【参考方案2】：

清理所有不需要的文件，从终端运行此命令

flutter clean && rm ios/Podfile ios/Podfile.lock pubspec.lock && rm -rf ios/Pods ios/Runner.xcworkspace
