DON'T BUILD UI COMPONENTS FROM SCRATCH

Your unified suite of Flutter UI components

While your app is one-of-a-kind, its buttons, text fields, navigation, and dialogs are not. Building these from scratch on every project wastes months of development. The LeanCode's Flutter Design System gives you bulletproof, maintained UI components so you can focus on what truly sets your product apart.
Design System for Flutter by LeanCode

Your fastest path to consistent UI

1
Launch features that matter, faster

Skip rebuilding the basics. With production-ready Flutter components and a complete token system already wired up, your team can immediately focus on the features that bring real value to your users.

2
Enterprise-level quality built in

The DS isn't just fast - it's solid. WCAG 2.1 AA and EAA compliant out of the box. Semantic token architecture. Proven component structure with variants and clearly described properties. A reliable foundation that scales as your team grows.

3
One change. Entire app updated

Components never use hard-coded values. They reference semantic tokens with the same names in Figma and in Dart. When a brand color changes, you update one token value. It propagates everywhere, automatically.

4
AI-ready out of the box

The quality of AI-generated Flutter code depends on how well the Figma file is structured. The DS meets every Figma MCP best practice: semantic layer names, variables for all tokens, Auto Layout throughout.

Everything you need in one system

Design and code, perfectly in sync. Four interconnected pillars that eliminate the gap between design intent and shipped code. Figma Components, Flutter Package, Widgetbook, and Documentation.
LeanCode Design System - Figma Components

Figma Components

Figma Components

A complete library of designed components with variants, properties, and behaviors. Every component uses semantic variables ready to rebrand for any client on day one.
LeanCode Design System - One language

One language, two disciplines

One language, two disciplines

Designers and developers work from the same source: tokens, naming, structure. Miscommunication becomes a thing of the past. What you see in Figma is what you get in the app.
LeanCode Design System - Figma documentation

Figma Documentation

Figma Documentation

Component descriptions, design principles, and usage guidelines live directly in the Figma file. Designers and developers share the same context without switching tools.
LeanCode Design System - Widgetbook

Widgetbook

Widgetbook

An interactive component browser. Every widget, every state, every property – browsable and previewable without opening Figma
LeanCode Design System - Design Tokens

Design Tokens

Design Tokens

The invisible backbone of consistency. Semantic color, spacing, typography, and radius tokens connect every component in Figma and Dart with the same names.
LeanCode Design System - WCAG Compliance

WCAG / EAA Compliance

WCAG / EAA Compliance

Every component meets WCAG 2.1 AA and European Accessibility Act requirements out of the box. No audit sprint, no remediation tickets.

There’s a lot more under the hood

When using the LeanCode Flutter Design System, you get access to every component below. Designed, documented in Figma, and built on a semantic token system. Implemented widgets are production-ready on day one.
