Flutter developer writing Dart code for a cross-platform app
Flutter app development company in India

One Flutter codebase. Android, iPhone, web and desktop.

A lot of businesses plan on hiring one team for Android and another for iPhone. With Flutter you don't need to. We write the app once, in Dart, and put it on the Play Store, the App Store, the web, and Windows or Mac if you want. It looks the same on all of them, and when we add something new, everyone gets it on the same day.

Cross-platform app development with Flutter

Why so many teams are moving to Flutter

It's not just the cost saving, though that's real. Flutter changes how fast you can try things, and how consistent your app looks from one phone to the next.

Single codebase for iOS and Android

One team, one set of bugs to fix, one release to test. Typically a big saving over two native builds.

Native-like performance

Flutter turns your app into native code and draws the screens itself, so scrolling feels smooth and animations don't stutter.

Hot reload development

Change a colour or a layout and see it on the phone in under a second. Design reviews happen live, not over email.

Widget-based UI

Everything on screen is built from widgets you can reuse. Design a button once, use it all over the app, and if you change it later you only change it in one place.

Cross-platform consistency

Your brand looks identical on a Samsung, an iPhone and a laptop browser. No more "why does it look different on Android?"

Dart programming language

Type-safe, null-safe and easy for most developers to pick up, which helps when you hire your own team later.

When we'd suggest something else

Flutter is a great fit for most business, consumer and on-demand apps. For heavy 3D games, apps built mostly around brand-new iOS-only features, or tiny utility apps where download size is critical, native can still be the better call. We'll tell you if that's you.

Under the hood

What it takes to make a Flutter app ready for real users.

Getting screens up in Flutter doesn't take long. The real work is making the app secure, properly tested and easy to update every week.

Firebase integration

We use the official FlutterFire packages to set up Firebase login, Firestore, push messages, Crashlytics and Remote Config.

Third-party plugin integration

Before we add any package, we check that it's well maintained. If nothing good exists, we write the platform code ourselves.

CI/CD for Flutter apps

We use Codemagic or GitHub Actions along with Fastlane, so each merge gets tested and a new build reaches your testers without anyone doing it by hand.

App store deployment

Google Play and App Store listings, signing, review notes and staged rollouts on both.

Scalable backend architecture

Our cloud APIs and databases are set up to handle heavy traffic on launch day, not only a handful of test users.

App security best practices

We obfuscate builds, store sensitive data securely, use SSL pinning, and keep API keys out of the app.

Flutter app migration services

Moving your existing app to Flutter, one screen at a time.

You don't have to rebuild the whole app at once. Flutter can sit inside your current native app, so we move it over section by section and you keep releasing updates the whole time.

Flutter migration team reviewing existing app code

Staged migration

Releases continue throughout

  1. 1

    Step 1

    Audit both apps

    Map screens, shared logic and the native features that need special care.

  2. 2

    Step 2

    Start with one flow

    Often settings or onboarding. It goes live inside the existing apps as Flutter.

  3. 3

    Step 3

    Move the rest

    Section by section, in normal releases. Users barely notice.

  4. Done

    Retire the old code

    One codebase, one team, and a much simpler release process.

Industries

Where Flutter really pays off

Flutter app development for e-commerce

E-commerce

Shopping apps with good product pages and a fast checkout, plus a web store that runs on the same code.

Flutter on-demand delivery apps

On-demand delivery

Customer, rider and store apps that share the same widgets, so building three apps costs a lot less than three separate projects.

Flutter app development for healthcare

Healthcare

Booking, teleconsults and records on phones, with a web portal for doctors on the same codebase.

Flutter app development for education

Education

Learning apps for students' phones and a desktop version for classroom screens.

Flutter app development process and timeline

Both app stores in roughly 12 weeks.

That's for a typical business app. Because there's one codebase, you get Android and iPhone in about the time one native app would take.

Week 1–2

Discovery

Features, platforms, integrations and what a good first release looks like.

Week 2–4

Design

Prototype and design system, turned straight into a widget library.

Week 4–10

Build

Sprints with test builds on both your Android phone and iPhone every two weeks.

Week 10–11

Beta

TestFlight and Play internal testing with real users, plus device QA.

Week 12

Launch

Submitted to both stores and released together.

For founders

Flutter app development for startups

For an early-stage product, Flutter is hard to beat. Both stores from one budget, quick changes after every round of user feedback, and a web admin panel thrown in. It stretches your runway further than almost any other option.

How to choose a Flutter app development company

Four questions worth asking

01

Try their Flutter apps on both platforms. They should feel right on Android and iPhone alike.

02

Ask about state management. Riverpod, Bloc, Provider. A clear answer means a tidy codebase.

03

Ask if they can write native code. Sometimes a plugin doesn't exist and someone has to write Kotlin or Swift.

04

Check for automated tests. Widget tests and CI are a good sign the app will stay stable.

Flutter app development cost

What a Flutter app costs

Price depends on how many screens you need, how much backend work there is, what you need to integrate and which platforms you want. Android and iOS share one codebase, so you'll usually pay a lot less than for two native apps. We'll send a detailed quote after a call.

Basic

Simple Flutter app

Android + iOS, login, 8–10 screens, Firebase backend.

Typical timeline: 6–8 weeks
Most common Standard

Business Flutter app

Payments, integrations, custom backend, admin web panel and analytics.

Typical timeline: 10–14 weeks
Advanced

Multi-app platform

Customer, partner and admin apps, real-time tracking, desktop or web versions.

Typical timeline: 4 months +

FAQ

Flutter questions, answered

How much does Flutter app development cost?
It depends on screens, backend and integrations. Since one codebase covers Android and iOS, it usually costs noticeably less than two native apps. We'll send an itemised estimate after a short call.
Is Flutter as fast as a native app?
For most apps, no one will notice. Flutter compiles to native code and draws its own screens, so it scrolls and animates smoothly. Native is still better for apps with very heavy graphics or 3D.
Why choose a Flutter app development company in India?
India has a large community of Flutter developers, so you can work with experienced people at lower rates. Our team in Lucknow works with clients in India and abroad, and our hours overlap with Europe and the US morning.
Can you convert our existing apps to Flutter?
Yes. We usually migrate in stages by adding Flutter screens into your existing native apps, so releases continue throughout and there's no risky big switch.
Can the same Flutter code run on the web too?
Yes. Flutter on the web works well for admin panels, dashboards and internal tools. For public websites that depend on SEO, we usually recommend a standard web stack alongside the app.
Who owns the Flutter code?
You do. Code, store listings, signing keys and backend all belong to you, assigned in the contract.
