This sounds like a concurrency issue, but I can't understand how this could happen since getAllContacts is guaranteed to be executed sequentially.

Are you sure you received exactly an empty list as a result and not an error?

Yes I'm getting the [] list sometime but printed Fetched 312 contact in console

Which is you printed in flutter code where you defined method channel

See my console i have printed which is null in console, then Fetched 1215 contacts
