# Pixel-identical UI with Flutter. One design across iOS, Android, web.

Flutter renders its own UI, so iOS, Android, and web look identical and pixel-controlled. We choose it when design consistency and custom UI matter most.

Stack

Flutter + Dart

Output

Production code + eval suite

Handoff

Full source ownership

\[THE SHORT VERSION\]

## Flutter owns the pixels, which is its superpower and its trade.

Because Flutter draws its own widgets, your design is identical everywhere and highly customizable. The trade is a different language (Dart) and a runtime that does not reuse native UI components.

When it fits

-   Brand-heavy apps that need identical, custom UI everywhere
-   Teams happy to standardize on Dart
-   One design system across mobile and web

\[HOW WE BUILD IT\]

## How we build with Flutter.

01

### Scope and fit

We decide where Flutter earns its place in your system, and where a simpler tool wins. No resume-driven architecture.

02

### Build on a tested foundation

We integrate Flutter against a foundation we trust: typed code, CI, and observability from the first commit. Boring infrastructure, modern surface.

03

### Eval before launch

An eval suite proves the build behaves before it reaches a user. We measure, then ship.

04

### Handoff with ownership

Your team gets the code, the tests, and a runbook. No lock-in to us or to a vendor framework.
