Hey @PawlikMichal25,

Thank you for creating a new issue! I'm having some difficulty reproducing it. If possible, could you please enable verbose logging for Ably and attach the logs to the issue?

Have you followed these steps: https://github.com/ably/ably-flutter/issues/531#issue-2408956689 with newest version of Ably and not got any errors?

Yes, I see. The fix currently only works for hot reloads; it doesn't apply to hot restarts because they recreate the app from scratch, and we rely on sequential IDs to sync listeners between the platform implementation and Dart code. Unfortunately, we’re unable to detect hot restarts to gracefully clean up listeners on the platform side. There is an open issue for this in the Flutter repo: https://github.com/flutter/flutter/issues/10437. We’ll work on refactoring the code to remove the need for sequential IDs for listeners, but I can't provide an ETA at this time. Since this issue only occurs during hot restarts in the development process, and the fix involves refactoring several parts of the codebase, it’s not currently a high-priority bug for us.
