The Problem Is That Fintech Teams Keep Rebuilding the Baseline UI
Generic component libraries aren’t built for financial products. Engineering teams routinely burn months hardcoding transaction lists, KYC flows, and token selectors before they ever touch the unique features that define their product's roadmap.
Months Wasted on Commodity UI
Instead of shipping core product value, frontend teams spend up to 60% of their early sprints building things every single banking app already has: wallet views, transaction history feeds, and onboarding forms.
The Figma-to-Code Game of Telephone
Manual Figma-to-code handoff is error-prone. As the product grows, the user experience fragments, and devs end up endlessly chasing styling bugs across different screens.
Generic Libraries Skip Fintech Specifics
Generic UI kits are built for basic SaaS apps, not money. They don’t solve for real-time price feeds, precision decimal formatting, gas estimation UX, or chain-agnostic wallet displays.
White-Label Delivery Without a System
Forking your codebase for every B2B client or new brand is a trap. Without an automated, tokenized multi-tenant system, managing custom themes across different rollouts turns every single release into an absolute merge-conflict marathon.
Fintech Design System for Flutter
Each layer can be consumed independently or as a complete stack. Adopt the UI components on day one, and opt into the full architecture when your team is ready.
Design Token System
Figma variables → JSON → Dart code automation. When designers ship brand or token changes in Figma, our automated build pipeline picks them up and generates the Dart code.
Component Library
Fintech-first Flutter widgets. You get plug-and-play, highly customizable primitives: transaction lists, wallet cards, token selectors, KYC forms, onboarding flows, statements, and dashboard primitives.
Theming Engine
Multi-brand, multi-mode theming with light and dark out of the box. Switch themes or entire client brands at compile-time with zero runtime performance cost and zero fragile conditional logic.
Navigation Module
Pre-wired routes for standard financial flows. This module contains pre-configured, deep-link-ready navigation paths for the critical flows every fintech shares: Auth, KYC verification, Account Dashboards, and Security Settings.
State Management Layer
BLoC-based screens with injectable API services. Because we pair BLoC with clean dependency injection, the codebase remains perfectly decoupled, making it just as easy to audit at a multi-million-user scale as it was during the MVP stage.
Material 3 Foundation
The entire system is built natively on top of Flutter’s mature Material 3 specifications. This ensures total forward-compatibility with the wider Flutter ecosystem, breaking changes are minimized, and future OS-level platform updates are supported natively.

One Codebase, Unlimited Branded Apps
Client apps don't fork FinKit, they override it. A single SDK serves an unlimited number of branded products with no merge conflicts and no per-client maintenance overhead.
Dependency Override Model
Client apps declare a resources package using identical names to FinKit's defaults. Dart’s build system cleanly shadows the SDK defaults at compile time. You get strict separation of code, zero asset bloat, and zero runtime performance cost.
Per-Brand Token Files
Each client supplies their own design_variables.json from their Figma file. The FinKit build runner processes the file and generates a brand-scoped scheme mapper that wires those exact tokens into the central theming engine.
Zero Code Drift
You maintain a single, clean core codebase. When you ship a security patch, compliance update, or new feature, it rolls out across every single client rollout simultaneously. No parallel maintenance branches.
Baked-In at Build Time
Because tokens and branding assets are compiled directly into the binary, your apps launch instantly. There is no runtime JSON parsing penalty and no jarring startup flash of unstyled colors.
Every Pattern a Fintech Product Needs
Already designed, accessible, and themed. The flows you'd build anyway.
Wallets & Balances
Multi-currency wallet cards, balance views, asset breakdowns, and chain-agnostic crypto wallet displays.
Transactions
Transaction lists, filters, search, statement views, receipts, and precision number formatting for fiat and crypto.
KYC & Onboarding
KYC forms, document upload, identity verification flows, sign-up wizards, and consent screens.
Tokens & Trading
Token selectors, price feeds, swap and exchange UIs, gas estimation widgets, and DeFi-friendly primitives.
Auth & Security
PIN entry, biometric prompts, OTP, SCA flows, session management, and secure pattern locks.
Cards & Payments
Virtual and physical card displays, card management, payment confirmation, and merchant detail views.
