One Codebase
Most features are built once and shipped to both platforms, which cuts duplicate engineering.
Flutter App Development
Launch one app on iOS and Android without paying for two separate builds. Pixel Flow Solutions is a Flutter app development company that takes mobile products from idea and design through APIs, testing, App Store and Google Play release, and ongoing updates, for startups and businesses in the US, UK and Canada.
Why Flutter
Flutter is Google's cross-platform framework for building mobile apps from a single codebase. It is a strong choice when your product needs to reach both iOS and Android with a consistent, branded experience.
Most features are built once and shipped to both platforms, which cuts duplicate engineering.
One component system keeps screens and interactions identical on every device.
New features and fixes move through one build pipeline instead of two separate projects.
Shared code means fewer places to update when your product changes.
App types
Focused first versions built around the core user journey so you can validate the idea before investing in a full roadmap.
Branded apps for bookings, memberships, ecommerce, loyalty, content and customer accounts.
Internal apps for field teams, inspections, approvals, data capture and task management.
Mobile versions of your web platform using the same backend, accounts and business logic.
Services
Pixel-accurate screens, animations and responsive layouts built from your approved designs.
Connections to REST and GraphQL APIs, Firebase, Supabase or your existing backend.
Camera, GPS, push notifications, biometrics, Bluetooth and other device features where your app needs them.
Key flows that keep working with poor connectivity and sync when the connection returns.
Secure sign-in, user accounts, Stripe payments and in-app purchases.
Event tracking and crash reports so you can see how the app is used after launch.
Stack
Fit check
Flutter works best when you need iOS and Android together, want a custom branded interface, share most business logic across platforms or need an MVP that can grow into a full product.
If your app depends heavily on brand-new platform features, specialized hardware or very different experiences per platform, we will tell you early and recommend the right approach.
Team extension
Already have a product team? You can hire our Flutter developers to extend your capacity. We work inside your repository, follow your code standards and join your sprint process, on a monthly or project basis. Agencies can also use us for white-label app development.
Existing apps
Add screens, flows and integrations while respecting the existing architecture.
Reduce duplicated components, messy state handling and technical debt that slow development down.
Find and fix slow screens, heavy rendering and inefficient data loading.
Plan a move from separate native apps or React Native when one codebase makes more sense.
Process
Define users, core flows, platforms, integrations and what version one must prove.
Turn requirements into screens and prototypes, connected to our UI/UX & Product Design work.
Set up the app structure, state management, data layer and environments.
Develop in short feature sprints you can review on real devices.
Check core flows, edge cases, devices, permissions and API behavior.
Prepare production builds and handle App Store and Google Play submission.
Launch
Release is part of delivery. We run release testing, prepare store listings and handle submission to the Apple App Store and Google Play. After launch, maintenance plans cover bug fixes, OS and package updates, monitoring and new feature work. Store approval is decided by Apple and Google, but we prepare every build to meet their guidelines.
Connected systems
Apps often connect to wider systems. We can connect your app to back-office processes through Business Workflow Development and add AI features such as chat assistants or smart search through AI Workflow Automation.
Proof
Our app case studies show the original idea or problem, the product decisions, the features built and the verified result.
FAQ
Flutter lets one team build a single codebase for iOS and Android with a fully custom interface. It reduces duplicate work and keeps both apps consistent.
Yes. The same Flutter project builds for both platforms, with platform-specific code only where a feature requires it.
Cost depends on the number of screens, features, integrations, backend work and design depth. We scope your first version and send a written proposal. See our Pricing & Engagements page.
A focused MVP usually takes a few months; larger apps with complex backends take longer. Your proposal includes a timeline for the agreed scope.
Both are solid cross-platform options. Flutter gives more control over custom UI and consistent performance, while React Native can suit teams already invested in JavaScript. We recommend based on your product and team.
Yes. We scope the smallest version that proves your idea, launch it and plan the next releases from real user feedback.
Yes. We connect to your existing APIs and authentication, and we can extend or clean up an existing Flutter codebase.
Yes. We prepare production builds, store listings and technical requirements, and manage the submission process.
Yes. Maintenance plans cover bug fixes, OS and dependency updates, monitoring and ongoing feature development.
