我一直在试图弄清楚如何制作cloud_firestore插件以实现功能，但到目前为止，还没有完成单个构建。我每次都有很多错误......我正在尝试为iOS iPhoneX模拟器构建
我已按照此代码实验室的说明操作：https://codelabs.developers.google.com/codelabs/flutter-firebase/ 我的代码与第9步完全相同
以下是错误：

我希望有人能对此有所了解，我对pods系统不是很熟悉，但我相信问题来自于此。

您可能需要在 pubspec.yaml 中更新您的依赖项。我在cloud_firestore v0.6.x中遇到过这个问题。我能够通过更新到最新的cloud_firestore来解决这个问题。我还更新到最新的firebase_auth。 （这些链接将带您到源，以便您可以找到当前的最新版本。）
<强> pubspec.yaml
dependencies:
flutter:
sdk: flutter
ons class for iOS style icons.
cupertino_icons: ^0.1.2
cloud_firestore: '^0.7.3'
firebase_auth: '^0.5.11'

我认为这可能与iOS pods发布的新v5（昨天）有关。这个和firebase有许多重大变化。我不熟悉颤动，但为我修复此问题的方法是在我的Podfile中将“pod'Firebase / Core'”更改为“pod'Firebase / Core'，'〜＆gt; 4.13.0'”。
