Overview
The growthbook_sdk_flutter package is an open-source feature flagging and experimentation platform that enables developers to dynamically control feature availability and run A/B tests without deploying new code. It integrates seamlessly into Flutter apps across Android, iOS, macOS, Windows, and Linux, allowing teams to test hypotheses, roll out features gradually, and personalize user experiences. With real-time flag evaluation and robust analytics support, it simplifies experimentation at scale. The SDK is lightweight, easy to set up, and designed for flexibility in both development and production environments.
