FeatureFlagExample

One of the key ingredients to speed up modern software development is using feature flags. However, they can still be quite a drag to integrate into your app as existing feature flag frameworks mostly focus on the remote toggling aspect of feature flags.

This repository shows a clear, very easy to use architecture to manage feature flags. The benefits are:

• Super easy to add feature flags: just a single LOC
• Support for local and remote feature flags
• Support for both feature flags (temporary for development) and test settings (indefintely to facilitate testing)
• Automatically generated UI to toggle feature flags in debug builds
• Able to use in unit/instrumentation testing
• Support any remote feature flag tool
