Flutter Best Practices

Standards for building maintainable Flutter apps, distilled from the official Flutter architecture guide and LeanCode's experience shipping 40+ Flutter projects (including a 30-developer banking app). Apply these when writing new code; when touching existing code, prefer consistency with the surrounding codebase and raise conflicts with these standards rather than silently rewriting.

How to use this skill

Read the reference file that matches the task. Read more than one when tasks overlap (e.g. a new feature touches both structure and coding style).
