Popular CI Tools for Flutter Projects

7.3.4 Popular CI Tools

In the journey from zero to the app store, Continuous Integration (CI) plays a pivotal role in ensuring that your Flutter app is built, tested, and deployed efficiently. CI tools automate the process of integrating code changes from multiple contributors into a single software project, making it easier to detect and fix bugs early in the development cycle. This section will provide an overview of some of the most popular CI tools suited for Flutter projects, discussing their features, advantages, and considerations.
