In this talk, we will share lessons from creating and maintaining a UIKit in Flutter. How to structure reusable widgets with multiple configurations, keep design parity with golden tests, and make documentation easy for other teams. We will also show how Widgetbook can help. Live, Interactive catalogs make it easier to explore widgets, test different states, and onboard new developers quickly.
We will also discuss patterns for large, multi-feature apps(SuperApps), how to manage consistency when dozens of modules use the same components, and how proper testing, documentation, and tooling prevent regressions. You will see real examples and learn practical tips to apply in your own projects.
Key Takeaways:
- How to design configurable, reusable widgets that scale across multiple teams and features.
- Using golden tests, widget tests, and Widgetbook to keep your design system reliable and discoverable.
- Best practices for docs, CI/CD, and developer experience so teams adopt the system seamlessly.
