Flutter at Scale: Lessons from Shipping 20+ Apps

Scale comes from conventions

Flutter teams move quickly when feature structure, state boundaries, and API clients are standardized. Without conventions, the codebase becomes the bottleneck.

Performance is a design choice

Large apps need careful image handling, rebuild control, and route-based loading. The difference between “smooth” and “janky” is often discipline rather than raw hardware.

CI/CD keeps the velocity honest

A fast app release cycle is only real when tests, linting, and build checks run before merge. Shipping often should not mean shipping blindly.
