Architecture: The LeanCode Guide
summary
Company builds 40+ Flutter apps and ships a reusable blueprint: a feature-based project structure that splits large features into extractable packages, a default of use cubits and hooks for state (95% cubit usage) with custom hook utilities, generated API contracts (OpenAPI or internal generator), and a copyable design system template with widgetbook, golden tests, and Figma-driven icons; also a custom LinkCode Forms solution for complex asynchronous forms that supports subforms, scroll-to-first-error and working integration with app components.
