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.
