Current problem

Support PostHog's official implementation for feature flags.

Preferred solution

For the MVP it could get as simple as just adding a isFeatureEnabled and follow up for multi variants and payloads .

@robingenz I'm opening a bounty for the requested feature request. I've made a $200 contribution on Open Collective. I'm also happy to contribute more if it's going to take more than two hours to implement full support for feature flags and experiments, but I think this is a good start.

I'm specifically looking at adding support for the following features:

• boolean feature flags
• reloading feature flags
• experiments (a/b tests)

There's also multi variate feature flags and the onFeatureFlags init callback which I'm less interested in, and are more of a nice to have.

@pondorasti Thank you for your contribution. I have attached the corresponding labels to the issue. I will take a look at this myself this week.
