Flutter Development Track Record
Why Flutter for Your Business
One codebase. iOS, Android, and web. Shipping in half the time.
True Cross-platform
Flutter compiles to native ARM code for iOS and Android from a single codebase. You ship to both app stores simultaneously instead of maintaining two separate engineering teams.
50% Lower Dev Cost
One codebase means one team, one QA cycle, and one deployment pipeline. Companies switching from separate iOS and Android teams to Flutter consistently report cutting mobile development costs in half.
Pixel-perfect Consistency
Flutter renders its own UI instead of wrapping native components. Your brand looks identical on every device and OS version, eliminating visual inconsistencies.
Faster Feature Velocity
Hot reload gives engineers instant visual feedback during development. Combined with single-codebase delivery, your team ships new features to both platforms in one sprint instead of two.
Google-backed Growth
Google uses Flutter for Google Pay, Ads, and Stadia. With 200,000+ apps on the Play Store built in Flutter and a growing talent pool, you're investing in a platform with serious momentum.
What We Build With Flutter
Cross-platform apps for mobile, web, and desktop from a single Dart codebase.
Cross-Platform Mobile Apps
Ship to iOS and Android from one codebase. Flutter's Impeller rendering engine compiles to native ARM code - no JavaScript bridge, no WebView, no compromise. Your app renders at 60fps (120fps on ProMotion devices) with pixel-perfect consistency across platforms.
Multi-Platform Apps (Mobile + Web + Desktop)
One codebase targeting six platforms: iOS, Android, web, macOS, Windows, and Linux. Flutter's widget engine renders everything itself rather than delegating to platform UI components, so your app looks identical everywhere. Ideal for internal tools, SaaS dashboards, and products that need to reach every screen.
MVP & Startup Apps
Validate on both platforms in 8-12 weeks. Flutter's Hot Reload lets developers see changes instantly without restarting the app - which means faster iteration during the phase where your product is changing daily. Code-level prototyping, not throwaway mockups.
Custom UI & Animation-Heavy Apps
This is where Flutter genuinely outperforms everything else. Flutter's own rendering engine (Impeller, built on Vulkan/Metal) means you're not limited by platform UI components. Complex animations, custom transitions, branded experiences, data visualizations - if you can design it, Flutter can render it at 60fps.
Enterprise & Compliance-Ready Apps
Offline-first architecture, biometric authentication, role-based access, HIPAA/SOC 2 compliance patterns. Platform channels for deep native integration when you need hardware access Flutter doesn't cover out of the box. Google Pay, BMW, and eBay trust Flutter in production.
App Migration to Flutter
Move from native iOS (Swift), native Android (Kotlin), React Native, or Xamarin to Flutter. We audit your existing codebase, identify what migrates cleanly and what needs rebuilding, and execute incrementally. Flutter 3.41's improved brownfield embedding means you can add Flutter views to existing native apps without a full rewrite.
When Flutter Makes Sense
The right framework for the job, not the trendy one.
Cross-platform mobile apps (iOS + Android)
Flutter’s Impeller rendering engine compiles to native ARM code. No JavaScript bridge, no WebView. Your app renders at 60fps with pixel-perfect consistency across platforms.
Multi-platform apps (mobile + web + desktop)
One codebase targeting six platforms. Flutter renders everything itself rather than delegating to platform UI components, so your app looks identical everywhere.
Custom UI and animation-heavy experiences
Flutter’s own rendering engine (Impeller, built on Vulkan/Metal) means you’re not limited by platform UI components. If you can design it, Flutter can render it at 60fps.
MVP validation on both platforms fast
Hot Reload lets developers see changes instantly without restarting the app. Validate on iOS and Android in 8-12 weeks, not 16-24 with two native teams.
Flutter isn't the right call for every project. Apps that need deep platform-native UI (following iOS HIG or Material Design exactly), or teams with existing React/JavaScript expertise where React Native would reuse skills better. We'll tell you upfront if something else fits.
Flutter vs React Native: When You Need What
We build with both. Here's how we decide.
Flutter (Dart)
Best for
Custom UI, animation-heavy apps, multi-platform (mobile + web + desktop)
Why
Flutter renders every pixel itself via Impeller. Complete design control, 60fps animations, and one codebase targeting six platforms. Ideal when your app needs to look and feel exactly as designed.
We use it when
Visual quality and brand consistency matter more than ecosystem breadth. You need web and desktop alongside mobile. Your team is open to learning Dart.
React Native (JavaScript)
Best for
Teams with JavaScript expertise, code sharing with React web apps
Why
JavaScript developers outnumber Dart developers roughly 20:1. If your team knows React, React Native lets you share business logic, types, and components between web and mobile.
We use it when
Hiring speed matters, your web app is already React, or you need the broadest possible talent pool.
Some projects use both. A Flutter mobile app for the consumer experience, a React Native companion for a partner-facing tool sharing the same backend. We architect for this when it makes sense.
From Concept to App Store
Working software every sprint, not just progress updates.
Discovery & Architecture (1-2 weeks)
Define screens, user flows, and technical architecture. Choose state management approach (BLoC for enterprise complexity, Riverpod for leaner projects). If you have an existing app, we audit it and plan the migration path. Deliverable: technical spec, Figma wireframes, architecture diagram.
Design System & Widget Library (1-2 weeks)
Build a custom widget library that implements your brand's design language. Flutter's widget composition model means every component is reusable and testable in isolation. Golden tests lock in visual correctness so UI doesn't drift as features ship.
Development & Iteration (6-16 weeks)
Sprint-based delivery. Hot Reload keeps feedback loops tight - designers and stakeholders can see changes in seconds, not hours. Internal builds distributed via Firebase App Distribution or TestFlight for real-device testing throughout.
QA, Performance & Launch (1-2 weeks)
Widget tests, integration tests, and golden tests for visual regression. Performance profiling with DevTools to ensure 60fps targets. Impeller-specific testing on both Vulkan and OpenGLES Android devices. App Store and Play Store submission via Fastlane or Codemagic.
Post-Launch & Maintenance
Bug fixes, OS compatibility updates (Android 16, iOS 26), and feature development. Flutter's quarterly release cycle (four stable releases planned for 2026) means the framework moves fast - we keep your app current.
