## AI overview

This tutorial explains feature flags, including static and dynamic variants, and describes how they control code paths without removing code from an app binary. It covers local and remote configuration, gradual rollouts, A/B testing, testability, and decoupling development from app releases.

## Source excerpt

A key ingredient to speed up modern software development is feature flags. But what is a feature flag precisely? Why should you care about them? How do you integrate them into your codebase?
