As mobile applications grow into large, long-lived systems, maintaining a clear and scalable codebase becomes increasingly challenging. This talk explores a production-proven architectural approach for large-scale Flutter applications, successfully used for several years in a product with millions of users and a multi-million-line codebase, developed by a team of 100+ mobile engineers. Built around a “LEGO” concept, where the application is composed of highly modular, interchangeable, self-contained building blocks, this architecture enables teams to develop and deliver features in isolation, while keeping the overall system consistent and maintainable. We’ll cover key aspects such as code organization, state management, navigation, dependency injection, configuration, testing, and more, along with the principles that guided these choices. You’ll leave with practical recommendations for structuring large codebases and scaling development without sacrificing efficiency or maintainability.

For years, "inclusivity" in mobile development has been treated as a synonym for standard accessibility compliance or simply adding a third option to a gender dropdown. But true inclusion runs much deeper—it’s baked into our database schemas, our form validations, and our UX assumptions. Back for their third year at FlutterCon USA, the Flutteristas are diving into the hidden nuances of identity and inclusion in tech. From the pitfalls of rigid form design to the unintentional exclusion in niche markets like parenting and tracking apps, this panel will explore how "inclusivity in the app" doesn’t always match real-world lived experiences. Join us for a practical, honest conversation on how to evaluate your apps from fresh perspectives, re-architect your data structures, and build software that genuinely represents the diverse world we live in.
