Ability to specify auth flow to trigger user migration events

[dreamorosi]

On which framework/platform would you like to see this feature implemented?

React

Which UI component is this feature-request for?

Authenticator

Please describe your feature-request in detail.

Customers wanting to run triggers like UserMigration_Authentication (docs) must use specific authentication flow types ) - i.e. USER_PASSWORD_AUTH.

The signIn function from aws-amplify/auth supports an option.authFlowType option (source) that allows to specify this, however I was not able to pass this when using the authenticator, nor find any mention in the docs.

Please describe a solution you'd like.

Ideally I'd like to set this parameter either in the amplify_outputs.json file or, if that's not feasible, be able to pass it to the withAuthenticator/<Authenticator> component as an option.

We love contributors! Is this something you'd be interested in working on?

Hi @dreamorosi , thank you for submitting the feature request. To override the auth flow type, i think you can try to override the signIn call by following the docs here though the example is showing how to override the signUp call but I think they share the same idea.

Hi @zchenwei thank you for the reply. I didn't see that section so I didn't make the connection that they're related.

I'll try that as soon as I can; in the meantime I'll close the issue.
