Flutter App Development .
iSkylar builds Flutter apps that look and perform natively on both iOS and Android, from a single, maintainable codebase. Whether you are launching an MVP or replacing a legacy mobile product, our Flutter team delivers pixel-perfect interfaces, smooth 60fps animations, and production-grade architecture that scales.
What We Build
Cross-Platform Apps
We ship a single Flutter codebase to both the App Store and Google Play — giving you full native performance and platform-appropriate UI on iOS and Android without maintaining two separate repos.
Consumer Mobile Products
Marketplace apps, on-demand services, fintech wallets, health trackers, social platforms — we design and build Flutter apps that users rate highly, return to, and recommend.
Enterprise Mobile Tools
Offline-first architecture, role-based access, SSO, push notifications, and MDM compatibility built into Flutter apps used by field teams, operations staff, and customer-facing employees.
Flutter Web & Desktop
Beyond mobile — Flutter runs on web browsers and macOS/Windows too. We extend your mobile product to additional surfaces without rewriting your business logic.
UI/UX Design for Flutter
Custom widget libraries, fluid animations, dark mode, and accessibility compliance — our designers use Flutter's rendering engine as an advantage, not just a constraint.
Migration to Flutter
Running an outdated React Native or native app that has become expensive to maintain? We migrate codebases to Flutter with feature parity preserved and performance improved.
Delivered faster with AI tooling
We don't just write code; we orchestrate intelligence. By integrating Copilot-assisted generation and AI-driven automated testing, we reduce time-to-market by up to 40%.
LLM-backed development to eliminate boilerplate delays.
Anticipating edge cases before they enter production.
The iSkylar Tech Stack
Our Development Journey
A streamlined, transparent path from vision to launch.
Discovery & Architecture
1–2 weeks
We define your feature set, user flows, and state management approach — and produce a technical spec you review and approve before design begins. No ambiguous handoffs.
UI/UX Design
2–3 weeks
High-fidelity Figma designs covering every screen, state, and transition. We design with Flutter's widget system in mind — so what you approve is exactly what gets built, not an approximation.
Development
4–14 weeks
Two-week sprints with a working build on TestFlight and Play Internal Testing after each one. You interact with the real app throughout — not screenshots or demos.
QA & Device Testing
1–2 weeks
Automated widget tests plus manual testing across iOS and Android devices covering different OS versions, screen sizes, and real-world network conditions including offline scenarios.
Store Submission
3–5 days
We handle App Store and Google Play submissions in parallel — metadata, screenshots, review guidelines compliance, and any back-and-forth with Apple or Google until both apps are live.
Post-Launch & Iteration
Ongoing
Crash monitoring via Sentry or Firebase Crashlytics, OS update compatibility, performance profiling, and feature iteration. We set up your CI/CD pipeline so future releases take hours, not days.

Frequently Asked Questions
Why Flutter over React Native or native development?+
Flutter gives you a single codebase that compiles to true native ARM code — not a JavaScript bridge. The result is 60fps rendering, faster build times, and one team maintaining one repo instead of two. For most new projects in 2026, it is the right default choice.
Can a Flutter app really feel native on both iOS and Android?+
Yes. Flutter renders its own UI using the Skia/Impeller engine, which means it is not constrained by platform UI components. We follow iOS and Android design conventions in our widget implementations — users cannot tell the difference.
How long does Flutter app development take?+
An MVP is typically 8–12 weeks from kickoff to both stores live. A full product with complex integrations and custom UI is usually 14–22 weeks. We give you a fixed timeline with milestones at the end of the scoping phase.
What does Flutter development cost?+
Pricing depends on feature depth, design complexity, and backend requirements. MVPs start from $10,000. We provide a detailed fixed-scope quote — you will know the full cost before signing, not after.
Do you handle both App Store and Google Play submission?+
Yes. We manage both submissions simultaneously — store listings, screenshots, content ratings, privacy policy requirements, and any review feedback — until both apps are approved and live.
Can you migrate our existing app to Flutter?+
Yes. We have migrated apps from React Native, Ionic, and native Android/iOS to Flutter. We start with a codebase audit, then migrate feature by feature with full test coverage preserved throughout.
Who owns the source code?+
You do. Full IP transfer of all Flutter code, Dart packages, assets, and CI/CD configuration is included at project close. We retain no rights or ongoing licence.
What post-launch support do you provide?+
We offer crash monitoring, OS compatibility updates, performance profiling, and feature iteration. Clients on a retainer get proactive monitoring and same-week response to critical issues.
