Flutter: Link an identity to a user

Links an oauth identity to an existing user. This method supports the PKCE flow.

• The Enable Manual Linking option must be enabled from your project's authentication settings.
• The user needs to be signed in to call linkIdentity().
• If the candidate identity is already linked to the existing user or another user, linkIdentity() will fail.

Parameters

• provider

  (Required)

  The provider to link the identity to.

• redirectTo

  (Optional)

  The URL to redirect the user to after they sign in with the third-party provider.

• scopes

  (Optional)

  A list of scopes to request from the third-party provider.

• authScreenLaunchMode

  (Optional)

  The launch mode for the auth screen. Defaults to `LaunchMode.platformDefault`.

• queryParams

  (Optional)

  Additional query parameters to be passed to the OAuth flow.
