【中文标题】在 iOS 中不推荐使用 Flutter 依赖项

【英文标题】：Flutter dependencies are deprecated in iOS

【问题描述】：

我知道许多 Flutter 开发人员在他们的应用程序中使用了许多不同的包。现在，我正在尝试在 ios 中构建我的应用程序的最终版本，但这让我很头疼。我正在使用诸如 image_picker、flutter_local_notifications、flutter_inappwebview、firebase_messaging 等软件包。由于 Firebase 库的兼容性问题，我需要将 min. iOS 10.0。

这些是一些库的版本，在构建到 iOS on Simulator 时会出错。

image_picker: ^0.6.7+22
flutter_local_notifications: ^4.0.1
flutter_inappwebview: ^4.0.0+4

# Only Firebase_messaging gives errors between Firebase libraries but 
# I would like to show you the versions of all of them
firebase_admob: ^0.11.0+1
firebase_messaging:
firebase_core: ^0.7.0
firebase_auth: ^0.20.0+1
cloud_firestore: ^0.16.0

与 firebase_messaging 相关的一小部分警告

还有这些不推荐使用的方法，警告输出中不推荐使用的 UI 元素错误。 当我以分钟为目标时。 iOS 9.0，这次GoogleMobilAds、FirebaseInstanceID、flutter_inappwebview-4.0.0+4等报错。

因此，无论我的目标是什么平台，在为 iOS 构建时我都无法避免错误和警告。知道如何解决由于弃用的东西而导致的长段错误消息吗？

【问题讨论】：

您通过更改代码而不是目标版本来修复弃用警告。或者您忽略它们（毕竟它们是警告）并在下次升级时处理技术债务。

@tehhowch 这不是忽略。我认为它阻止我在 iOS 中构建应用程序。有没有其他建议的可能性？你认为这是因为 Xcode 中的新构建系统吗？

【参考方案1】：

升级到新的 Flutter 版本解决了我的问题。如果有人看到这一点，请考虑升级您的依赖项和 Flutter。

【讨论】：

我在 Flutter 2.5.3 (codemagic) 中仍然收到那些“在 iOS 10.0 中首次弃用”的警告。

【参考方案2】：

我遇到了同样的问题，即使我将 minimumOSVersion 设置为 11.0 ，并且 IPHONEOS_DEPLOYMENT_TARGET 设置为 11.0 ，仍然显示不推荐使用的错误，可能是 Xcode 的问题，顺便说一句，我使用 Xcode 12.4 和 12.2 仍然错误
