Flutter
one codebase,
native feel

Cross-platform mobile apps for iOS and Android from a single Dart codebase. Custom UI, real native performance, and the kind of shipping speed that lets you learn from users before the budget runs out.

Single Dart codebase that compiles to iOS and Android
Custom UI that does not look like every other template app
Native module access for camera, sensors, payments, and Bluetooth
Release engineering and store submission handled end to end

Two platforms, one deadline, and a team that is already tired.

The pitch is "one codebase, two stores." The reality is a long list of native gaps, plugin surprises, and tooling that punishes the unready. We have walked into those rooms and cleaned them up.

iOS and Android ship weeks apart because the teams speak different languages.
A plugin that worked on Android falls apart on iOS, and the maintainer has gone dark.
Build times balloon to twenty minutes and every CI run costs real money.
The "free" UI kit looks like every other app on the store.
State management wars turn the codebase into a Bloc versus River versus Provider cage match.
Native modules are written in three languages and glued with platform channels nobody understands.
App size creeps past 80 MB and onboarding drops off a cliff.
Release day means a Friday-night ceremony that no one wants to own.

A mobile app is the part of your product users touch every day. When builds break, plugins rot, and releases slip, the roadmap pays the price in trust. We build Flutter apps that ship on schedule, hold up at scale, and feel native on both stores.

Three reasons teams pick our Flutter work.

Not just because the framework is fast. Because we know what native quality looks like once the demo glow fades.

01

Native feel, custom UI.

We design custom widgets and motion that match the brand, not a template. Flutter's render engine gives us pixel control on iOS and Android — without two design systems to maintain.

"They have stayed involved as the product evolved, helped us think through new requirements."

02

Consumer apps, MVPs, field tools.

Food delivery, fitness, marketplaces, internal field apps. We build Flutter products where the user journey runs deep and the time to both stores matters more than a perfectly native scroll bar.

"Now we can clearly show our users what products we have. The payment system is simple and easy."

— Dave Chiu, Managing Director, Teafolks

03

Native modules done right.

Camera, MLKit, Bluetooth, payments, push, biometrics. We write platform channels in Swift and Kotlin when the plugin does not exist — or fork and maintain the ones that do.

"I was impressed with their level of motivation, which I found to be unparalleled in the outsourcing world."

— Vladimir Cvejanovic, CTO, StockStudio

How we build with Flutter.

A repeatable path from "we need an app on both stores" to a release the team can own.

01Product & UX Audit
02Architecture & State Plan
03Build & Native Bridges
04Test, Release & Monitor

We start with the user journey and the native quirks — platform conventions, gestures, and store rules — then design the Flutter architecture around them. State, navigation, and platform channels get decided in week one, not in the middle of a launch. Depending on the product, we bring in mobile app development for the full build, MVP development when speed to both stores is the priority, and dedicated teams for long-term capacity.

"Extending essential functions to Antagosoft has allowed us to take on more internal parallel projects."

— Ryan Fyfe, CEO, Humanity.com

When Flutter might not be the right fit:

  • You need a deep, single-platform-native experience with platform-specific UI conventions.
    For pure-native iOS or Android with platform-specific design, look at React Native or going fully native with Swift and Kotlin.
  • Your team is built around Swift-first or Kotlin-first and has no appetite for Dart.
    A cross-framework rewrite usually costs more than it returns. We will tell you honestly when it does not make sense.
  • You need a 5 MB web companion with no app store presence.
    A web app or a PWA will get you there faster and cheaper than shipping a mobile build for it.

Built with Flutter.

Real products where Flutter ships the same iOS and Android experience from a single codebase.

Healthcare & Wellness

Telemedicine platform with secure video and chat.

HealthHub connects patients and psychologists through mobile-first booking, video, and chat. The Flutter app shares the API layer and design system with the clinician web dashboard, so releases ship together on both platforms.

Logistics & Transport

Smart parking app with real-time spot tracking and payment.

Smart Parking needed a mobile experience for drivers to find, reserve, and pay for parking spots in real time. Flutter delivers the same smooth experience on iOS and Android — with real-time map updates, in-app payments, and push notifications for expiry reminders.

Why build Flutter with us?

We have shipped Flutter products in production.

Consumer apps, internal field tools, MVPs that grew into platforms. We know which Flutter patterns survive a real user base and which ones collapse under it.

We are not afraid of native code.

When the plugin is broken or missing, we write Swift and Kotlin to fill the gap. Your app gets the native feature, not a Dart workaround that ships later.

Release engineering is part of the build.

CI, code signing, store listings, phased rollouts, and crash monitoring come standard. Friday-night releases stop being a thing.

Quick answers.

Flutter or React Native — how do you choose?

Flutter when custom UI, animation control, and one-team velocity matter most. React Native when the team is deep in JavaScript and wants to share web code with the app.

Can you take over an existing native or Flutter app?

Yes. We audit the codebase, write down what is salvageable, and ship fixes module by module so the app stays live while we work.

How do you handle state management?

Bloc or Riverpod for complex products, Provider for simple ones. The choice is made early, defended in code review, and used the same way across the team.

Do you handle App Store and Play Store submission?

Yes — signing, listings, screenshots, privacy manifests, and review responses. We stay on the call with Apple and Google when something goes sideways.
