We've shipped multiple Flutter apps with seven-figure user bases. Here's what we'd tell our past selves.
What Flutter does brilliantly
- UI consistency — your app looks identical on every device
- Hot reload — sub-second iteration cycle is genuinely transformative
- One team, two stores — 60% less code, 60% less ongoing maintenance
- Custom design — pixel-perfect brand expression without per-platform pain
Patterns that worked
- Feature-first folder structure — beats layer-first as the app grows
- Riverpod + go_router + freezed + Dio — stable architectural quartet
- Codegen for API clients — saves hundreds of hours over time
- Visual regression testing — Golden tests catch UI breaks
Bottom line
Flutter is the right call for product teams that want one codebase and premium UI without shipping web wrappers.
