Data-change-listener is not supported by design. We suggest using something like event-bus to notify any interesting clients. Doing this inside a storage framework smells really bad.

how to use with eventbus when we don't have any callback from the value changes?

Whoever makes the change should notify any interesting partners, if any changes on that specific key are meant to be heard. MMKV, as a fundament KV storage framework, chooses not to take that responsibilty.
