firebase - 无法使用 Flutter 和 cloud_firestore 构建项目

Question

我一直在努力弄清楚如何让 flutter 的 cloud_firestore 插件正常工作，但到目前为止，还没有一个构建完成。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进行操作:https://codelabs.developers.google.com/codelabs/flutter-firebase/我的代码与第 9 步完全相同

这里是错误:

$ flutter run

我希望有人对此有所了解，我对 pod 系统不是很熟悉，但我相信问题出在此处。

Answer 1

您可能需要在 pubspec.yaml 中更新您的依赖项。我在使用 cloud_firestore v0.6.x 时遇到了这个问题。我能够通过更新到最新的 cloud_firestore 来解决这个问题.我也更新到最新firebase_auth . (这些链接会将您带到源代码，以便您找到当前的最新版本。)

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'
