Apple sign-in video will also come out soonish. In the mean while, what other Flutter content would you like to see on this channel?

[nikitachernenko]

dude, you saved my day!! It was pretty non-obvious for me before where I need to use android service id vs web service id, and why it is web service id for android if I use native sign in...
mobile dev is slightly confusing, but thanks a lot!!

[hantuedan]

Supabase have to add the crucial feature for all real word app like transaction native feature or batch on db. Otherwise we can't chose supabase to to make a good apps.

[michaelrogers]

This was quite clear for the most part, but there were 3 different client IDs, which one gets pasted into Supabase?

It seems I haven't found a tutorial for Sign in with Apple using Supabase and Flutter.
By the way, how can I link multiple OAuth logins to the same account? I mean binding both Apple and Google to the same account.
Of course, it should also work for Web and Android

[gkumartube]

[wgolyoko]

The google_sign_in plugin `signIn` method is deprecated on the web, and will be removed in Q2 2024.

[giaretz]

The login on iOS works perfectly but the one on Android doesn't work. It keeps giving me the same error Unhandled Exception: PlatformException(sign_in_failed, 10:, null, null)
