LinkIdentity does not work

[heeween]

Describe the bug
Email login and anonymous login, when manually linking a Google account, will redirect to the Google interface, then back to the default official website, and there are no further prompts. After returning, the link was not successful; requesting getUserIdentities still only shows one identity.

Automatic linking

It done Automatic linking for email users
When a new user signs in with OAuth, Supabase Auth will attempt to look for an existing user that uses the same email address. If a match is found, the new identity is linked to the user.

Manual linking

await Supabase.instance.client.auth.linkIdentity(OAuthProvider.google, redirectTo: "loginCallBackUrl");

add deeplinking to handle callback actions

You need to enable manual linking from your project's authentication

manually linking works for me

Thank your reply. I have switch on the 'Allow manual linking' in my project. And i am integrate supabase by this code. The console log will output 'Google sign-in response: true'. But when i get back the user ientities have only one object.
final response = await supabase.auth.linkIdentity( OAuthProvider.google, ); print('Google sign-in response: $response');
