Hire Flutter Developers for iOS and Android Apps
RED SAG assigns dedicated Flutter developers from our team in Tamil Nadu, India, to businesses in the USA, UK, Australia, Canada and India. They write Dart, ship one codebase to both app stores, and work inside your repository, board and chat so the app moves forward at the pace of your own team.
Flutter suits products that need a polished, consistent interface on iPhone and Android without paying for two native teams: booking apps, field-service tools, fintech wallets, loyalty apps and internal apps for staff. Our developers also pick up existing Flutter projects that were started quickly and now struggle with state management, slow builds or outdated packages after a Flutter upgrade. If you would rather hand over the whole app, we also work as a Flutter app development company in India, with fixed-scope Flutter app development services from first design to store release.
Hire a Flutter developer full time, part time or hourly, or ask for a fixed quote on a defined app or release. You can begin with a one-week paid pilot on a real ticket, such as a new screen or a crash fix, before you commit to a monthly arrangement.
What our Flutter developers build for you
Customer apps for iOS and Android
Ordering, booking, membership and account apps with authentication, push notifications through Firebase Cloud Messaging, deep links and offline-friendly screens, released to both stores from one codebase.
Fintech and payment apps
Wallet, lending and payment screens that integrate Razorpay, Stripe or UPI intents, handle biometric login with local_auth, and store tokens securely with flutter_secure_storage.
Field and staff apps
Apps for delivery staff, sales teams and technicians with camera and barcode capture, GPS, background sync and a local database such as Drift, Isar or Hive for poor connectivity.
Apps backed by Firebase or Supabase
MVPs that use Firebase Auth, Firestore, Cloud Functions and Crashlytics, or Supabase for Postgres-backed data, so a small team can launch without building a full back end first.
Flutter upgrades and package clean-ups
Moving old projects to null safety and current Flutter releases, replacing abandoned packages, fixing Gradle and CocoaPods build failures, and bringing Android and iOS targets up to current store requirements.
Flutter web and desktop companions
Admin or kiosk versions of your mobile app built with Flutter web or desktop where it makes sense, with an honest view of where a React or Next.js front-end would serve you better.

Junior, mid-level or senior
Pick the level that matches the work. Many teams pair one senior developer with a junior or mid-level developer to keep costs down without losing review quality.
Junior
1–3 years
Builds screens and widgets from designs within an architecture a senior developer has set.
- Build responsive layouts from Figma using the app's theme and widgets
- Connect screens to existing repositories and state providers
- Write widget tests for the screens they build
- Fix layout overflows and platform-specific UI bugs
Mid-level
3–6 years
Delivers complete features across both platforms and handles native integration questions.
- Design state and data flow for a feature with Riverpod or Bloc
- Integrate REST APIs, push notifications, payments and maps
- Prepare builds for TestFlight and Play Console testing tracks
- Diagnose crashes from Crashlytics reports and fix root causes
Senior
6+ years
Owns app architecture, release process and performance, and can guide other mobile developers.
- Set project structure, flavors, environments and coding standards
- Write platform channels or plugins when a package does not exist
- Set up CI/CD with Codemagic or GitHub Actions and Fastlane
- Profile jank with Flutter DevTools and lead Flutter version upgrades
Common Flutter problems our developers avoid
Business logic inside widgets
API calls and rules written straight into build methods make screens impossible to test. Our developers keep logic in repositories and notifiers or blocs, so widgets only render state.
Rebuilding the whole screen on every change
Watching a large provider at the top of a page redraws everything on each keystroke. We scope listeners narrowly, use const constructors and check rebuild counts in DevTools.
Package sprawl
Pulling in a pub.dev package for every small need leaves apps stuck when one is abandoned. Developers check maintenance and platform support first, and write small helpers themselves where sensible.
Ignoring platform differences
Permissions, back navigation, keyboard behaviour and notch handling differ between iOS and Android. We test on real devices for both, not just one emulator, before a build goes to the stores.
Ways to hire
Four ways to work with our Flutter developers, and when each one makes sense for Flutter work.
Full-time dedicated developer
One developer works only on your product, around 160 hours a month, inside your tools and sprint rhythm.
Right when the app is your main product and you release regularly, with a backlog of features, store updates and fixes every sprint.
Fixed monthly fee, invoiced monthly
Part-time dedicated developer
The same developer every week for about 80 hours a month, usually half days or agreed days.
Good for a live app that needs steady upkeep: package and SDK updates, store policy changes, and a feature or two each month.
Fixed monthly fee for the agreed hours
Hourly
Pay only for tracked hours against tickets you raise. Hours and task notes are shared with every invoice.
Helpful for a crash investigation, a failing iOS build, a store rejection or a review of an app another team wrote.
Tracked hours, invoiced monthly
Fixed-price project
A written scope, a fixed quote and milestones. We carry the estimate risk; changes are quoted before they are built.
Fits a defined build such as an MVP from approved designs, a Flutter version upgrade or adding payments to an existing app.
Milestone payments against an agreed scope
Indicative rates for Flutter developers

How we vet and assign Flutter developers
Technical interview
A senior engineer on our side interviews every developer on the stack you are hiring for, covering the topics listed on this page, before they are put forward to any client.
Review of real work
We read code the developer has written, from our own projects or their earlier work, looking at structure, naming, tests and how they handle errors, not just whether it runs.
Practical trial task
A short task in the same stack, done in a real repository and reviewed like a pull request. It shows how someone works, asks questions and writes up what they did.
Matched to your brief
We put forward the developer whose experience fits your product and time zone, share a short profile, and you interview them yourself before anything is signed.
What the Flutter interview covers
- Widget lifecycle, BuildContext and keys, and what causes unnecessary rebuilds
- Choosing and structuring state management with Riverpod or Bloc
- Async Dart: Futures, Streams, isolates and error handling
- Platform specifics: permissions, deep links, push notifications and native configuration files
- Release process for App Store Connect and Google Play, including signing and versioning
The trial task
Build a two-screen Flutter app against a mock API: a paginated list with pull-to-refresh and an offline cache, and a detail screen with a validated form. State in Riverpod or Bloc, a repository layer, and widget tests. We review it as a pull request and run it on both an Android and an iOS simulator.
How onboarding works
- 01
Call and NDA
A short call about your product, stack and team. We sign your NDA, or ours, before you share code, designs or business details.
- 02
Profile and interview
We share the profile of the developer we recommend and you interview them. A match usually takes about a week, depending on availability.
- 03
Contract and IP
The contract assigns all code and work product to you once invoices are paid, and sets out rates, hours, notice and confidentiality.
- 04
Access through your tools
You invite the developer to your GitHub or GitLab, Jira or Linear, and Slack or Teams. You control access and can revoke it at any time.
- 05
Updates you can rely on
A written update at the end of every working day, a weekly summary with hours, what shipped and what is blocked, and a demo when you want one.
The developer's first week
- Build and run the app on Android and iOS, including every flavor, and note any build problems
- Read the state management, routing and API layers and agree the conventions to follow
- Check the Flutter version, key packages and store targets for anything close to a deadline
- Ship a small real fix or screen through your review and a TestFlight or internal testing build
Working hours overlap
Our team is in India (IST, UTC+5:30). These are the overlap windows we plan around; the exact hours are agreed in the contract.
United Kingdom
Our normal day (9:00–18:00 IST) covers roughly 9:00 am to 12:30 pm in London in winter and 9:00 am to 1:30 pm in summer. A developer working 11:00–20:00 IST can cover until about 2:30 pm GMT.
USA and Canada (Eastern)
On a shifted schedule the developer is online for about 9:00 am to noon Eastern (New York, Toronto), enough for stand-up, reviews and questions. Work carries on overnight and is ready in your morning.
USA and Canada (Pacific)
For California or Vancouver we agree a fixed early window, typically 7:00–9:00 am Pacific, plus written hand-offs at the end of your day. We are open that overlap is shorter here.
Australia
India is 4.5 to 5.5 hours behind Sydney and Melbourne, so our normal day overlaps your afternoon, roughly 1:30–5:30 pm AEST. Perth overlaps from about 11:30 am onwards.
Try before you commit
Start with a one-week paid pilot
Before committing to a month, you can start with a one-week paid pilot. The developer works on a real ticket from your backlog, in your repository and tools, with the same daily updates as a normal engagement. At the end you decide whether to continue, change developer or stop. The pilot is billed at the hourly rate for the hours worked, and the code is yours.
Replacement if it is not a fit
If the developer is not the right fit, tell us and we will replace the developer at no extra charge. The new developer is briefed from the shared notes and tickets, and we overlap the hand-over where we can so you do not lose momentum.
Hiring Flutter developers: questions
How much does it cost to hire a Flutter developer from India?
As an indication, a full-time dedicated Flutter developer from RED SAG costs roughly $1,700–3,500 a month depending on seniority, and hourly work about $15–30 an hour. The rates table shows the same ranges in GBP, AUD, CAD and INR. The exact rate is confirmed in writing before any work begins.
Who owns the Apple and Google developer accounts?
You do. We recommend the app is published under your own Apple Developer Program and Google Play Console accounts, with our developer added as a team member. That way the listing, signing keys and reviews stay with your business, and you can remove our access at any time.
Will the developer handle App Store and Play Store submission?
Yes. Our Flutter developers prepare signed builds, manage TestFlight and Play testing tracks, fill in privacy and data-safety forms with your input, and respond to review feedback. If a build is rejected, they read the guideline cited, fix the cause and resubmit.
Should we choose Flutter or React Native?
Both are sound choices. Flutter gives very consistent UI across platforms and strong performance for custom designs. React Native suits teams that already use React and TypeScript on the web. If you have an existing codebase, the right answer is usually to keep it; we can advise after looking at your project.
How quickly can a Flutter developer start?
Usually within a week, depending on availability and how closely your app matches a developer's experience with your state management and back end. If the best match is busy for a little longer, we will say so rather than assign someone less suited.
What if the Flutter developer is not the right fit?
Let us know what is not working. We will replace the developer at no extra charge and hand over through your tickets and our notes. The one-week paid pilot is there so you can assess fit on a real task before committing to a month.
Can you take over a Flutter app built by someone else?
Yes. We start by building the app for both platforms, listing outdated packages and deprecated APIs, and reading the state and navigation code. You get a short written report with risks and a suggested order of work before we change anything significant.
Do we need separate Android and iOS developers?
Usually not. Many teams who set out to hire Android developers in India, and then hire iOS developers separately, find that one Flutter developer covers both apps from one codebase. Where a feature needs platform code, such as a home-screen widget or a native SDK without a Flutter plugin, our Flutter developers write the platform channel in Kotlin or Swift. For a purely native app, tell us on the first call and we will say honestly whether we have the right person.
Can you build the back end for our Flutter app too?
Yes. Most Flutter apps need an API, an admin panel and push notifications behind them. If you want to hire a backend developer alongside your Flutter developer, we assign a Node.js or Django developer from the same team, so both sides agree the API contract from the start. Firebase is fine for simpler apps, and we will tell you when it is enough.
How do you compare with other Flutter app development companies?
We would rather not claim to be the best; judge us on the work. We publish indicative rates, start with a one-week paid pilot on a real ticket, keep the code and store accounts in your name, and replace a developer at no extra charge if the fit is wrong. Ask any team you are comparing for the same things in writing.
