The sendCustomChallengeAnswer (javascript) does not work in flutter with ConfirmSingIn (flutter)

[juanrequeijo]

Describe the bug
My login sends a custom OTP code to the user's email to confirm ownership of the email. Using the javascript lib function sendCustomChallengeAnswer the user sends the OTP code he received in the email. In flutter, the equivalent function confirmSingIn shows the following error:

underlyingException:"java.lang.IllegalStateException: confirmSignIn called after signIn has succeeded"

Six months ago the lib didn't support this custom flow:
#276

Still not working?

To Reproduce
Steps to reproduce the behavior:
0. Define a Custom auth challenge:
https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-lambda-create-auth-challenge.html

1. Call:
   await Amplify.Auth.signIn(
   username: emailController.text, password: passwordController.text);
2. Call:
   Amplify.Auth.confirmSignIn(
   confirmationValue: confirmController.text);

Expected behavior
The functions return with the tokens and the user's complete session logged in:
await Amplify.Auth.fetchAuthSession();
await Amplify.Auth.getCurrentUser();

Platform
x Android

@juanrequeijo We have discussed this as a team, and we are going to prioritize adding this functionality.

Thank you for working on this. May I know a possible time frame when this feature available in amplify flutter sdk? This would be helpful for me to decide my project's authentication flow.

Since this is part of the custom auth feature, I'm closing this in favor of #410. Please follow that ticket for the latest info including release timelines and notifications.
