`Concurrent modification during iteration` issue in Amplify Core about amplify-flutter HOT 5 CLOSED

Hello @Fleximex - Amplify.reset() is an internal API. It is not intended to be used outside of Amplify packages. What is your use case for calling this API?

from amplify-flutter.

We are aware Amplify.reset() is not battle tested for production, and thus not intended for production. In our case, however, we have a multi tenant solution where, on runtime, Amplify needs to be reconfigured for a different identity and user pool (won't open a separate issue/discussion for that since amplify-flutter, amplify-swift and amplify-android all have multiple open already).

This issue though, doesn't exclusively relate to Amplify.reset(). Whether or not Amplify.reset() is used to execute the close() method, in the mentioned file. It modifies the list it is iterating over. Which should not happen regardless.

from amplify-flutter.

The exception indicates that either addInstance or create is called at the same time as or immediately after close. I am not sure we want to allow that. It might hide other issues.

Are you calling reset() immediately after addPlugin() or configure()? Are you awaiting the calls to addPlugin() and configure()?

from amplify-flutter.

@Fleximex Please let me know if you are awaiting the calls to addPlugin and configure. It would help if you can share the code snippet that results in this. We use Amplify.reset() in many of our integration tests I do not see this occur.

@Fleximex I am going to close this out since we have not heard back. If you are still facing this issue please share the info requested above. Thanks.
