Flutter development

One codebase. Every screen looks right.

Flutter draws every pixel itself, so your app looks exactly as designed on every iPhone and Android device. That makes it a great fit for brands that care about custom UI, rich animation and a consistent experience, without paying for two separate native apps.

Our Flutter team uses proven architecture patterns such as Riverpod or Bloc, automated tests and CI/CD with Codemagic, so the codebase stays clean as your product grows. When a feature needs platform code, we write it in Swift or Kotlin through platform channels.

Custom UI & animation

Brand-specific design that looks identical everywhere.

Fast development

Hot reload and shared code speed up every sprint.

Multi-platform

Mobile, web and desktop from the same codebase.

What we build

Flutter development services in depth.

Flutter can power mobile, web, desktop and embedded screens. Here's what each type of Flutter project includes.

iOS and Android from one Dart codebase

Our most common Flutter work: consumer and business apps with custom designs, smooth animations and native integrations, delivered to both app stores.

What you get

  • Custom UI that matches your brand exactly
  • Riverpod or BLoC architecture
  • Payments, maps, camera and push notifications
  • Offline storage with Drift or Hive
  • Arabic RTL and multi-language support
  • Widget, integration and golden tests
  • CI/CD with Codemagic or GitHub Actions

Technology

Example use case

Salon booking app

Problem
A salon chain needed a branded booking app on both platforms with a small budget.
Our solution
A Flutter app with stylist selection, slot booking, deposits and loyalty points.
Expected outcome
Both stores launched from one codebase, and the team updates one app instead of two.

One codebase beyond mobile

Flutter also targets web, Windows, macOS and Linux. It's ideal for dashboards, admin panels and internal tools that should match your mobile app.

What you get

  • Flutter web admin panels and portals
  • Windows and macOS desktop apps
  • Responsive layouts for every screen
  • Keyboard and mouse support
  • Shared business logic with mobile

Technology

Flutter WebFlutter DesktopResponsive Frameworkfl_chartIsar
Example use case

Clinic management suite

Problem
A clinic used separate tools for the reception desk and the patient app.
Our solution
A Flutter patient app plus a Flutter desktop reception app sharing the same code and API.
Expected outcome
One team maintains both, with consistent data and design.

Fast backend for launching quickly

For MVPs and real-time apps, we pair Flutter with Firebase or Supabase for authentication, databases, storage and functions, moving to a custom backend when you outgrow it.

What you get

  • Authentication with email, phone OTP and social login
  • Real-time database and chat
  • Cloud functions for business logic
  • File storage and image resizing
  • Analytics and Crashlytics
  • Remote Config for feature flags

Technology

Example use case

Community chat app

Problem
A startup needed real-time chat and feeds for an investor demo.
Our solution
Flutter with Firestore for live chat and feeds, and Cloud Functions for moderation.
Expected outcome
A working, scalable demo with a clear path to a custom backend.

Keep your Flutter app healthy

We upgrade old Flutter versions, fix performance problems, replace abandoned packages and add tests, so your app keeps passing store requirements.

What you get

  • Code and architecture audit
  • Flutter and Dart version upgrades
  • Null safety migration
  • Replace abandoned packages
  • Fix jank and memory issues
  • Add test coverage

Client testimonials

What our clients say about us.

"What impressed us most about UD3 Logic was their ability to understand the healthcare industry rather than treating the project like a standard software development assignment. They invested time in learning how our hospital operates, the challenges faced by our staff, and the expectations of our patients before proposing solutions. This resulted in a platform that felt practical and intuitive instead of being overloaded with unnecessary features.

Another standout quality was their willingness to collaborate. They welcomed feedback throughout the project, refined features based on our evolving requirements, and consistently focused on finding the best long-term solution instead of the quickest fix. Their technical expertise, combined with clear communication and genuine commitment to our success, made the entire engagement feel like a true partnership.

Even after the primary development work was completed, they continued to provide valuable support and enhancements, which gave us confidence that the solution would continue to evolve alongside our organization."

Ask a question
WhatsApp +91 98874 87026
Q1What is Flutter and why use it?

Flutter is Google's open-source framework for building apps from one Dart codebase for iOS, Android, web and desktop. It renders its own UI, so apps look the same on every device and support rich animation. Companies choose it to launch faster, reduce cost and keep one consistent design.

Q2Are Flutter apps as fast as native apps?

For most apps, yes. Flutter compiles to native ARM code and uses its own rendering engine for smooth scrolling and animation. Only very graphics-heavy apps, such as advanced 3D games, typically need fully native code.

Q3Can Flutter apps use device features like the camera and GPS?

Yes. Flutter has mature packages for the camera, location, Bluetooth, biometrics, payments and notifications. If something is missing, we write a native plugin in Swift or Kotlin.

Q4Is Flutter good for large, long-term products?

Yes, with the right architecture. We use clear layers, state management such as Riverpod or Bloc, automated tests and code reviews so that large Flutter codebases stay easy to change.

Q5Can I hire dedicated Flutter developers from you?

Yes. You can hire one or more Flutter developers full-time or part-time. They work in your time zone overlap, join your tools and stand-ups, and are backed by our senior team for reviews.

Q6Can you migrate my existing app to Flutter?

Yes. We usually rebuild the app in Flutter module by module, reusing your backend and APIs. Users move to the new version through a normal store update.

Q7Does Flutter work for web apps?

Flutter web is great for app-like experiences such as dashboards and internal tools. For public, SEO-heavy websites we usually recommend a separate web front end, so your pages rank well in Google.

Q8How long does a Flutter app take to build?

A focused Flutter MVP typically takes 8โ€“10 weeks, and a full-featured app around 3โ€“4 months. Multi-app platforms take longer. We share an exact plan after a free discovery call.

Q9Does Flutter support Arabic and RTL?

Yes. Flutter has built-in RTL support and localisation tools, and we design screens to mirror correctly for Arabic users.

Q10Can Flutter use native iOS and Android SDKs?

Yes. Flutter uses platform channels to call native code, so we can integrate any SDK, such as payment gateways or hardware devices.

Q11Can Flutter build desktop apps?

Yes. Flutter supports Windows, macOS and Linux, which is useful for internal tools and admin apps that should match your mobile app.

Q12Should I use Firebase or a custom backend with Flutter?

Firebase or Supabase is great for MVPs and real-time features. A custom backend suits complex business rules, integrations or strict data residency needs. We often start with Firebase and migrate later.
