Flutter 'google_sign_in' 构建因 GTMAppAuth 问题而失败 - 未定义符号 _GTMBridgeAssetValid

【问题描述】：

如果我添加了 google_sign_in 包，我将无法构建 iOS 应用程序。

如果我尝试在 Flutter 稳定通道上构建项目，那么我从 Xcode 构建中得到错误输出： XCode 输出

【问题讨论】：

  • 尝试手动删除 pod 文件和 podlock 文件然后运行应用程序，让我知道结果以获得进一步帮助。
  • 我已经删除了pod文件和podlock文件，然后flutter clean，pod install。但未能构建同样的问题。
  • 您是否为 iOS 正确配置了 google_sign_in？如果还没有，请参考这里：pub.dev/packages/google_sign_in#ios-integration
  • 是的。我已经根据 iOS 集成指南从第 1 步到第 7 步（ GoogleService-Info.plist 和 Info.plist ）对其进行了配置。我也为 sign_in_with_apple 配置了它。但也未能构建相同的问题（未定义符号：_GTMBridgeAssetValidSelector）。它适用于 Flutter 稳定版 1.22 和 firebase 旧版本包。
  • 您是否在 Firebase 身份验证方法部分启用了 google 登录？

【解决方案1】：

我未能使用 GTMSessionFetcher 1.6.0 构建 iOS 应用程序。 所以我不得不通过编辑 Podfile 手动将其降级到 1.5.0。 我在 Podfile 中添加了以下行，然后运行“pod install”并再次构建项目，它可以工作。

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
  pod 'GTMSessionFetcher', '= 1.5.0'  # add this line.
end

我发现 GTMSessionFetcher 的最新版本是 1.6.1。 但无法使用

pod 'GTMSessionFetcher', '= 1.6.1'
