Expo-go React-Native application that uses Google Authentication in Firebase
问题
我正在使用Expo构建React-Native应用程序，并使用Expo Go进行测试。我需要使用Google来对Firebase用户进行身份验证。
我成功地使用电子邮件+密码对Firebase用户进行了身份验证，但无法使用Google进行身份验证。
我已经花了好几天的时间在网络（以及Stack Overflow）上寻找解决方案，但没有找到明确的或真正有效的示例。
提出的方法包括：'signInWithRedirect'和'signInWithPopup'（在React-Native中都不适用），'expo-google-sign-in'（已弃用）和'Expo-auth-session'（似乎是最新的方法，但很多人声称它在expo-go中不起作用）。
我正在尝试的事情是否可能？是否有任何可用的示例？
否则，有没有推荐的方法来在我的应用程序中使用Google对Firebase用户进行身份验证（例如，使用构建而不是expo-go，或使用Expo Dev Clients来增强expo-go等）？请提供任何有效的示例。
非常感谢，我感到非常绝望 
英文:
I am building a React-Native application with expo and test it with expo-go. I need to authenticate users to Firebase using Google.
I managed to authenticate users in Firebase with email+password, but not with Google.
I have spent several days looking for solutions on the web (and Stack-Overflow) and could not find anything definite or an example that actually works.
The proposed methods were: 'signInWithRedirect' and 'signInWithPopup' (both do not work in React-Native), 'expo-google-sign-in' (deprecated) and 'Expo-auth-session' (seems to be the latest method, but many claim it does not work with expo-go).
Is what I try to do even possible? is there a working example anywhere?
Otherwise, what would be the recommended way to authenticate users with Google in Firebase in my application (e.g., use builds instead of expo-go, or use Expo Dev Clients to enhance expo-go, etc.) - any working example please?
Many thanks in advance, I am getting desperate

我成功地通过Expo SDK 47在Expo Go上使Firebase Google身份验证工作。随着2023年2月发布的Expo SDK 48，我认为在Expo Go上无法再使其工作。请参阅SDK 48更新的说明。
我曾不愿迁移到Expo Dev Clients，但它比预期的顺利，所以我建议勇敢尝试并继续使用Expo Dev Client。我认为您需要一个付费的苹果开发者帐户来创建构建。我使用这种方法遇到的另一个问题是，我似乎无法在预览构建中使身份验证流程工作，尽管在开发构建中可以正常工作。请参阅我的问题此处，其中嵌入了我的代码示例，该示例在开发构建中可以正常工作。
英文:
I managed to get firebase google auth working through Expo Go using Expo SDK 47. With the release of Expo SDK 48 in February 2023, I believe it is no longer possible to get it working with Expo Go. See explanation of the SDK 48 updates here.
I was reluctant to migrate to Expo Dev Clients, but it went smoother than anticipated, so I would recommend biting the bullet and moving forward with Expo Dev Client. I believe you will need a paid apple developer account to create the builds. The other issue I'm having with this method, is that I cannot seem to get the authentication flow working in a preview build, although it works fine in the development build. See my question here which has my code sample embedded, which works with the development build.

经过浪费了荒谬的时间（大约一周）后，我最终放弃了，转而使用React-Native CLI而不是Expo。仅仅几个小时之内，使用React-Native-Firebase包（使用原生代码）进行Google身份验证时，我没有遇到任何问题。
（顺便说一句 - 我尝试在dev-client中使用React-Native-Firebase，但无法使其正常工作）
英文:
After spending a ridiculous amount of time on this (about a week) I finally gave up and moved to React-Native CLI instead of Expo.
In just a few hours, using the React-Native-Firebase package (that uses native code) I had no problems authenticating with Google.
(BTW - I tried to use React-Native-Firebase in a dev-client, but was not able to make it work)

抱歉，代码部分不提供翻译。以下是已翻译的部分：
"A bit late to the party guys, but we've just spent about 2 days making it work. Check out our blog post about it. It is definitely possible, even with Expo SDK 48. There is a link in the blog post to a git repo included where you can find a working example. Hope it helps some of you. :)"
