Fully Enable a Feature Flag

You can toggle any feature without re-deploying, and all reads of feature flag values are always performed entirely local to your application to avoid roundtrip network requests. You can think of this as boolean feature flipping where it's either true or false for everyone.

In this example, the Demo is behind a flag named demo. To enable (or disable) it, you can use the Flipper API, Flipper UI, or Flipper Cloud. In most cases, you wouldn't let folks toggle features for themselves like this, but it can be handy for letting them opt-in to test out new features ahead of a public release.
