Sign In With Redirect

Use the signInWithRedirect method to allow users to sign in to the application using a redirect mechanism with an OAuth provider.

This option of user authentication is similar to the sign-in with popup auth method.

Ensure that your OAuth provider option has been enabled in your Firebase project.

Method

await FirebaseApp.firebaseAuth?.signInWithRedirect(providerId);

Parameters

• providerId (String): The OAuth provider ID (e.g., 'google.com', 'facebook.com') for the sign-in.

Return

• void: This method does not return a value.

This method initiates the OAuth sign-in process by redirecting the user to the provider's sign-in page, typically used for third-party authentication like Google or Facebook.
