Describe the bug I can't compile my (android) app in release mode after upgrading google_sign_in_android to 6.1.22. I get errors (10+) like:

[ +1 ms] Missing class com.google.android.gms.auth.api.credentials.CredentialPickerConfig$Builder (referenced from: void fman.ge.smart_auth.SmartAuthPlugin.requestHint(io.flutter.plugin.common.MethodCall, io.flutter.plugin.common.MethodChannel$Result))

To Reproduce Steps to reproduce the behavior:

1. Have both smart_auth and google_sign_in_android latest versions in a flutter project with android
2. flutter build apk --release --verbose

Screenshots N/A

Additional context So, going through the release notes, google_sign_in_android says they upgraded play-services-auth to 21.0.0 (url) The release notes of play-services-auth say that there is a major breaking change: they removed Credentials API! (https://developers.google.com/android/guides/releases#february_15_2024) The settings.gradle of this plugin I see it depends on play-services-auth 20.7.0 (https://github.com/Tkko/flutter_smart_auth/blob/be97b1bcfb3169d90ab5792393afea574d964630/android/build.gradle#L56)

I guess 21 is preferred over 20.7 during compilation, so no wonder why those classes mentioned in the error log can not be found.

This is why I think this is worthy of a bug report for smart_auth: can you please support the new Credential Manager API?

Did you implemented the Credential Manager API?

Hi @Tkko @gourgouris i am ready to take up this issue but before starting i want some more info about that with the latest version we get something known as GetPhoneNumberHintIntentRequest.builder() which is completely different from the previous versions, whats you take on this ? Like i want to know your views on this

Edit i am taking about this version implementation 'com.google.android.gms:play-services-auth:21.2.0'

In version 3.0.0 com.google.android.gms:play-services-auth: was upgraded to 21.3.0. Additionally, I removed the com.google.android.gms:play-services-auth-api-phone:18.0.1 and added new credentials manager. So, this should not be a problem anymore, feel free to open the issue if it isn't solved in new update.
