Hello @annikaschmid !

I understand that there is a proposal to unify the posthog-java and the posthog-android SDK, which makes sense from a code base standpoint. I hope my pull requests help with building the foundations for the base classes, if these end up not being merged.

I just wanted to bring to your attention that I have implemented an MVP version for feature flags in Java. Should be in the following PRs:

1. feat: feature flag polling for local evaluation (1/4) posthog-java#54
2. feat: integrate feature flag poller to PostHog client (2/4) posthog-java#55
3. feat: send feature flag event to product analytics (3/4) posthog-java#56
4. feat: get all feature flags related to a distinct_id (4/4) posthog-java#57
5. feat: Java SDK feature flags posthog.com#8593

CC @jamesefhawkins a follow up of our Friday conversation 😄

When will this be done?

It's important because on java usually written backends, where one of the main things - activation of some logic based on Feature Flags

Also I would like to add, that we need local evaluation support for FF too, so we don't need to care about how many call's we generate to /decide endpoint. Otherwise it makes production integration in Java hard to do.

Wondering if there is any update on this issue, will this be available any time soon?
