Don’t Break the Brand: Maintaining a Design System in Flutter
Building reusable widgets in Flutter is easy. Building a design system that scales and stays consistent over time is not.
As applications grow, design systems often turn into “widget dumping grounds”: inconsistent APIs, duplicated styles, and components that slowly drift away from the original design intent. Without clear boundaries, a solid theming foundation, and proper validation workflows, even well-intentioned systems become hard to use and harder to trust.
Drawing from our experience building and evolving the design system behind the Holafly app, we’ll share real-world challenges, trade-offs, and lessons learned while scaling a production UI system.
Whether you’re starting a design system from scratch or trying to regain control of an existing one, joining us in this talk will give you practical tools to ensure your code remains a source of truth rather than a source of frustration.
