Top Flutter Storybook or Component Driven UI Development packages
Last updated: June 22, 2025
Component driven UI development is a methodology for building user interfaces that focuses on creating self-contained, reusable components. Or in terms of Flutter, we can say every component of UI, i.e., a widget is built in isolation. Thus, you don't need to spin up the whole Flutter app just to see how they render. You can render a specific variation in isolation by passing in props, mocking data, or faking events. This approach can help to make your code more maintainable and testable, and can make it easier to create complex UIs.
This development paradigm was made popular by Storybook.js and Flutter packages like Storybook, Dashbook, Widgetbook, etc. have made it possible for Flutter developers.
The complete list of Component Driven UI development Flutter packages is provided below.
