Hi @SercanKaya0

Do you have your code uploaded to a public repo where I can take a look at?

Also, could you confirm that you have done deep link set up as described here? https://supabase.io/docs/guides/with-flutter#setup-deep-links

[SercanKaya0]

Hello Tyler, Yes, I did it step by step, there is no open repo, but if you send an e-mail, I can send you an invitation, or I can picture the codes, I can do whatever is comfortable.

@SercanKaya0 Sure, in that case, maybe if you could upload your code to a separate public repo, that might be the easiest!

[SercanKaya0]

For you public tyler, You can find Supabase Helper in core/supabase/ https://github.com/SercanKaya0/ilango

@SercanKaya0 Thanks for this. Also, which platform were you using when you experienced this issue? iOS, Android, or web?

Also, which social login type did you test and did not come back to the app?

Lastly, what happens instead of coming back to the application? Does it just stay in the browser at localhost:3000?

[SercanKaya0]

iOS and android

There is another error, ios sends the following error when social login with real device for the 2nd time

PlatformException (PlatformException(Error, Error while launching https://cccxxxx.supabase.co/auth/v1/authorize?provider=facebook&redirect_to=ilango%3A%2F%2Flogin-callback%2F, null, null))

@SercanKaya0

Hi Tyler, i fix android just iOS don’t work

Great! What was the cause on Android?

So is it just Facebook login that you are testing, or are you using other login providers as well?

In addition to that, what happens when you fail to login? Does it take you to localhost:3000, or are you getting 5XX errors on browswer?

There is another error, ios sends the following error when social login with real device for the 2nd time

Could you explain in detail step by step to reproduce this?

[SercanKaya0]

It was erroneous with a slight / jump of mine on the Android device.

I got the error on all social logins. I tried facebook, google and got an error.. 1 - I am attaching the error I received after logging in as an image. 2 - The first time I sign in with the real device, only error supabase-community/supabase-dart#1 happens, but if I try to login for the 2nd time, it does the same error I mentioned in the previous commit.

[phamhieu]

I am attaching the error I received after logging in as an image.

I can't find your error image. Can you check again @SercanKaya0.

[bdlukaa]

This issue is happening to a lot of people. I'd recommend to wait for supabase-community/supabase-dart#5 to be fixed to use providers.

[KirioXX]

Hi, I see the same error when I try to use apple authentication on a iOS simulator and on a iOS device: it seems like the redirect to supabase is somehow failing, but when I close the window the authentication was successful. Are there any updates on that issue or can I somehow help to debug it?

[dshukertjr]

Thanks for following up @KirioXX!

Do you happen to have a public repo that we can take a look at with this issue?

[KirioXX]

No, sadly not it is a private project. But I'll be going to try to recreate it in a public project and come back to you.

[dshukertjr]

@KirioXX That would be awesome! Thank you so much for your help.

[KirioXX]

@dshukertjr Here you go: https://github.com/KirioXX/supabase_flutter_test_apple_auth That is pretty much the same setup that I have in my private project and it throws the same exception. Please let me know if I can help with anything else.

[dshukertjr]

@KirioXX thank you so much for this! I am also seeing the issue on an emulator. I will try to spot the cause on my end as well.

In the meanwhile, I noticed that in the screenshot you provided, the error says it's trying to open Supabase URL that starts with http and not https. Maybe there's something there?

[KirioXX]

Good spot @dshukertjr, I had the wrong URL there. But I see the same error with https:

[ashbressler]

Wanted to add a few things that I have observed while getting the same error.

1. If you look in the supabase admin, you can see that the last logged in date is updated, so things seem to be working on the back end side with getting the auth from Facebook.
2. Looking that the URL that's being launched, for me it's of the form: https://[myproject].supabase.co/auth/v1/authorize?provider=facebook&redirect_to=[my app id]%3A%2F%2Flogin-callback%2F, it seems as if part of the string is URL encoded (the redirect_to) but the rest of the URL string is not. This seems to be similar to the images in previous comments.

Base on item 2, is it possible that url_launcher is tripping up because it's trying to URL encode the entire URL string and throwing an error because part of it is already encoded? I have not dug into the code yet, but will try to when I'm back at my computer

[ashbressler]

I believe that it's this line in the GoTrue library that's causing the issue: https://github.com/supabase/gotrue-dart/blob/b9e8a88fedd4b7ca541d836b708d1afc27ff9bb2/lib/src/gotrue_api.dart#L308

I'll try to fork the GoTrue library and modify locally to see if it fixes the problem

[ashbressler]

Had a chance to dig in a bit. It seems that (on iOS at least, I have some other issues with Android right now so I can't confirm) that when you open a browser window in app it trips up on the redirect_to not being one of the supported url_launcher URL Schemes. Meaning that the redirect is back to a custom URL like com.test://login-callback and I think the in app browser window just can't handle that. Or it's possible that the in app browser doesn't support custom URL schemes.

What I did was add the parameter forceSafariVC: false to this line https://github.com/supabase/supabase-flutter/blob/57ad86984a4044fb471d164f4042342d5f1adb66/lib/src/supabase_auth.dart#L170 and it now launches the default browser, I sign in to the provider, it then asks me to launch my app and when I click yes it's then fully logged in.

One other thing I tried was to add something like this to the info.plist, thinking that iOS was blocking the custom URL scheme, but it didn't work:

<key>LSApplicationQueriesSchemes</key>
	<array>
		<string>[my custom scheme from the redirect_to]</string>
	</array>

Not sure if this is the proper solution.

I'm happy to submit a pull request if that would be helpful.

[c0c4i]

Any updates?

[marcocondrache]

Same problem here, +1

[Jay-flow]

I'm experiencing the same problem.

supabase-community/supabase-flutter#84

It does not return to the app only on iOS.

[ashbressler]

Update on my solution that does not require any to supabase-flutter.

In looking at the code for signInWithProvider, I realized that it was just calling signIn, which returns the provider login URL, and then launching the web view myself.

So I changed my login with Facebook to look like:

final response = await supabase.auth.signIn(
      provider: Provider.facebook,
      options: AuthOptions(
          redirectTo: kIsWeb ? null : 'com.my.url://login-callback/'),
    );
final success = await launch(response.url!,
    webOnlyWindowName: '_self', forceSafariVC: false);

Again, not sure if this is the best solution, but it's been working well for me and I don't have to change any of the supabase libraries so I'm happier with that.

[ashbressler]

One more update, so when I submitted the app using what said above it got rejected for launching the web browser and not a web view.

Looking at things again I saw that I was getting the auth messages in the debug console. So I added closeWebView() in my AuthState/onAuthenticated method and that seems to work ok.

I know the team is working on native auth flows so I think that should really help, but hopefully this works short term.

[Jay-flow]

@ashbressler Thx bro It's worked for me :)

The url_launcher package was updated 6.1.0 and the expression changed a little.

 GotrueSessionResponse res = await supabase.auth.signIn(
      provider: provider,
      options: AuthOptions(
        redirectTo: kIsWeb ? null : 'com.my.url://login-callback/',
      ),
    );

    if (res.url != null) {
      Uri authUri = Uri.parse(res.url!);
      await launchUrl(
        authUri,
        webOnlyWindowName: '_self',
        mode: LaunchMode.externalApplication,
      );
    }

      ),
    );

    if (res.url != null) {
      Uri authUri = Uri.parse(res.url!);
      await launchUrl(
        authUri,
        webOnlyWindowName: '_self',
        mode: LaunchMode.externalApplication,
      );
    }

This method is not available for Apple login. The loading screen continues to repeat. As the answer to @ashbressler , you must exit the web view directly.

Future<void> signInWithSocial(
    Provider provider,
  ) async {
    GotrueSessionResponse res = await supabase.auth.signIn(
      provider: provider,
      options: AuthOptions(
        redirectTo: kIsWeb ? null : 'app.artcalendar://login-callback/',
      ),
    );

    if (res.url != null) {
      Uri authUri = Uri.parse(res.url!);

      try {
        await launchUrl(
          authUri,
        );
      } on PlatformException {
       // Handling iOS Error Exception
        if (Platform.isAndroid) {
          rethrow;
        }
      }

      return;
    }

    alertError(t('SOCIAL_LOGIN_FAIL'));
  }

  @override
  void onAuthenticated(Session session) async {
    if (Platform.isIOS) {
      // Exit Login Web View
      await closeInAppWebView();
    }
  }

I know this is a temporary solution, but it works right now.

The following error is printed on iOS, and this seems to be a fundamental problem. It happens when I come back to the app from the safari.

how you fixed it? I encounter same problem.
