fetchSignInMethodsForEmail method
Returns a list of sign-in methods that can be used to sign in a given user (identified by its main email address).
This method is useful when you support multiple authentication mechanisms if you want to implement an email-first authentication flow.
An empty List is returned if the user could not be found.
A FirebaseAuthException maybe thrown with the following error code:
- invalid-email:
- Thrown if the email address is not valid.
Implementation
Future<List<String>> fetchSignInMethodsForEmail(String email) {
throw UnimplementedError('fetchSignInMethodsForEmail() is not implemented');
}
