如何使用 fastlane 缩短 Flutter iOS 应用程序的构建时间

Question

我的问题是，当使用 Firebase 时（cloud_firestore特别是），Flutter iOS 应用程序的构建时间变得很长，以至于我在 Bitrise 上的 CI 构建超时（28flutter build --release分钟，fastlane 的 20 分钟以上build_ios_app）。所以我无法在我的 CI 上执行完整的 iOS 构建。缓存当然是可能的，但首先必须完成初始构建：/

根据本指南，在使用 Fastlane 使用 Xcode 进行存档时，有必要重建 iOS 应用程序。然而，在官方 Github 存储库上有一个关于引入直接从 Flutter 发布 IPA 文件的命令的讨论，但目前这是不可能的。

我的问题是 - 有没有什么方法可以缩短这个构建时间，例如通过跳过 fastlane 步骤中的构建，只是将 .app 文件辞职并存档到 .ipa？我不能自己让它工作。

在这里，你可能会发现一个样品扑应用与cloud_firestore功能。

您可以在下面找到我的 Bitrise 和 fastlane 配置：

这是快速通道：

我遇到了同样的问题，我使用https://github.com/invertase/firestore-ios-sdk-frameworks的 Cloud Firestore 框架的预编译二进制文件修复了这一问题，如下所示：

# ...
target 'Runner' do
  pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '6.26.0'

# ...
end
