Flutter Development Services — Custom Apps Delivered on One Codebase
Custom Flutter development services from a Flutter-specialist team. iOS, Android, web, and desktop from a single Dart codebase. Fixed scope, source-code delivery, no surprises. Trusted by operators since 2010.
What custom Flutter development actually includes
Custom Flutter development is the work of taking a product spec and shipping a finished Flutter application — iOS binary, Android binary, optionally Flutter web and Flutter desktop — under your brand, with your backend, integrated to your payment processors, and handed over with the full source code at the end. That is what this page sells. We are a flutter app development company that has built in this stack since 2010, and the page deliberately does not try to sell you anything else.
What is included as standard on a custom Flutter engagement at IFA: discovery and written scope, Figma design for every screen, the Flutter app itself (one codebase, native iOS and Android binaries), a backend if you do not already have one (NestJS on MongoDB), payment gateway integration, push notification setup, App Store and Google Play submission under your developer accounts, three months of email support, and the full Git repository at handover.
What is honestly not included by default and is worth naming up front: Apple Developer Program enrolment ($99/year, your account); Google Play Console enrolment ($25 one-time, your account); App Store Optimisation and paid user acquisition; vendor recruitment if you are launching a marketplace and need supply-side onboarding; and any third-party SaaS subscriptions (Mapbox tier, Stripe processing fees, push provider quotas above the free tier). We line-item every excluded cost in the scope document so the quote is the quote.
Flutter development services we offer
Custom Flutter app builds
Ground-up Flutter apps for iOS and Android, scoped from a discovery call to a fixed quote. The full Dart codebase is delivered at handover.
App migration to Flutter
Existing React Native, native iOS, native Android, or Cordova apps re-platformed onto a single Flutter codebase. Feature parity first, then improvements.
Flutter UI / UX design
Design that compiles. Figma to Flutter, with the GetWidget component library as the production foundation. No throwaway mockups.
Backend, APIs, and integrations
NestJS REST or GraphQL APIs on MongoDB, payment gateway integration (Stripe, Razorpay, Adyen), maps, push, third-party SDKs.
Flutter web and desktop
Same Dart codebase compiled to Flutter web (responsive PWA) and Flutter desktop (Windows, macOS). Useful for admin dashboards and operator tools.
Post-launch support and feature work
Ongoing maintenance, OS-version upgrades, and net-new feature sprints at a fixed hourly rate. The team that built the app extends it.
Most engagements pull from two or three of the above. A solo restaurant operator typically takes a custom build plus design plus backend. An enterprise migrating from React Native typically takes the migration service plus ongoing post-launch support. We scope the mix on the discovery call. For platform-agnostic mobile work where the Flutter-vs-native question is still open, see our broader mobile app development services page; this page assumes Flutter is the chosen stack.
Hire, build, or license — which path is right for you?
Before reading the rest of the page, it is worth knowing which of three Flutter paths you actually want. Each has a different price, a different timeline, and a different vendor inside the IFA / paiteq family. Picking the wrong one wastes everyone's time.
- Hire — staff Flutter engineers onto your team. You have a product manager, designs, and you want engineers who slot into your standups and ship inside your repo. This is hireflutterdev.com, our sister company. AI-augmented Flutter engineers from $18/hr with a hire-by-the-week or monthly retainer model. Not this page.
- Build — commission a custom Flutter app end-to-end. You have a product idea or a working prototype and you want a fixed-scope team to deliver the whole thing. Discovery, design, build, ship. That is what this page is. From $18,000 to $80,000+, six to sixteen weeks.
- License — buy a readymade Flutter source code package. Your use case (food delivery, grocery, restaurant ordering, home services) is something we have already shipped in production. Skip the build cycle, take the source, brand it, deploy it. From $1,500 to $5,000, days to six weeks. Browse the readymade Flutter products catalogue.
| ★ Custom build (this page) | License a readymade product | |
|---|---|---|
| You need engineers on your team | Not this page — visit hireflutterdev.com | Not this page — visit hireflutterdev.com |
| You want a custom app built end-to-end | Yes — request a quote on this page | Not the right path |
| You want a working app today, low budget | Possible — but readymade is faster | Yes — browse /products/ |
| You own the source code at the end | Yes — full Flutter codebase at handover | Yes — Single Extended License |
| Typical investment | $18,000 to $80,000+ | $1,500 to $5,000 |
| Typical timeline | 6 to 16 weeks | Days to 6 weeks (branding pass) |
If you read those three rows and your answer is "I need engineers, not a built product", stop reading and head to hireflutterdev.com. We deliberately do not staff Flutter hire from this side of the business; the sister site does it better and on a different commercial model.
What we build in Flutter — mobile, web, and desktop
Flutter compiles a single Dart codebase to native binaries on six targets: iOS, Android, Flutter web (WebAssembly or HTML renderer), Windows, macOS, and Linux. In practice almost every IFA engagement ships three of those — iOS, Android, and Flutter web for an operator-facing dashboard. The remaining three (Linux, macOS, Windows desktop) are added on request, usually for internal tools.
Mobile, the default
iOS and Android are the core deliverables. Flutter renders directly to a Skia or Impeller canvas with no JavaScript bridge, which is why scrolling, animations, and live-tracking maps stay at 60fps on mid-range Android hardware where React Native typically drops frames. Native bridges to camera, biometrics, secure storage, in-app purchase, push, and geolocation are wired through first-party plugins. Stripe, Razorpay, Adyen, Apple Pay, Google Pay, and UPI are pre-integrated.
Flutter web for operator dashboards
Flutter web development is the right call when the dashboard needs to share business logic and data models with the mobile apps. An operator looking at the same orders the customer placed should not need a second engineering team to build a separate React admin panel. We ship Flutter web for restaurant dashboards, vendor consoles, dispatcher panels, and admin CMSes — all reusing the Dart code already written for mobile.
Backend, infrastructure, and CI
The default backend stack is NestJS on MongoDB with Redis for queues and caching. APIs are REST by default, GraphQL on request. Hosting is your choice (AWS, DigitalOcean, GCP, or self-host); we ship Docker-Compose configs and deployment notes. CI is GitHub Actions: every push runs Dart analyzer, unit tests, widget tests, and integration tests; merges to main build TestFlight and Play Internal artefacts automatically. Sentry catches crashes in production. None of this is bolted on at the end; it is wired from sprint one.
Flutter vs React Native vs native — why we build in Flutter
One codebase, iOS + Android
Flutter compiles a single Dart codebase to native iOS and Android binaries. You ship two apps without maintaining two separate codebases or two separate engineering tracks.
60fps on every screen
Flutter renders directly to a Skia/Impeller canvas — no JavaScript bridge, no WebView overhead. Every scroll, transition, and live-tracking update runs at 60fps on mid-range Android hardware.
One team to maintain and extend
Because the entire stack — customer app, vendor app, driver app — is Dart, a single Flutter developer can fix a bug and redeploy to both stores. No context-switching between Swift and Kotlin teams.
Faster release cycles
IFA ships Flutter apps. Our 250+ Flutter developers have delivered readymade products and custom builds since 2010. When you need a new feature, the team that built the product extends it — no handoff friction.
The four cards above are the short version. The longer answer about platform choice, which buyers asking for flutter mobile app development often want before signing, comes down to four engineering trade-offs.
Render path: no JavaScript bridge
React Native renders to native UIView and android.view through a JavaScript-to-native bridge. Every animation frame round-trips through a serialised JSON payload. That works fine on flagships and stutters on the mid-range Android hardware most of your users actually own. Flutter renders directly to its own Skia or Impeller canvas, no bridge, no marshalling. The visible result is 60fps scrolling on a $200 Android phone instead of 45fps with occasional frame drops.
Single codebase, single team, single PR
Native iOS and Android development means two codebases (Swift / Kotlin), two CI pipelines, and the operational reality of every feature being built twice by two specialists who must coordinate. A single Flutter developer can fix a bug and redeploy to both stores from the same pull request. For an operator, the practical effect is that adding a new delivery zone or a new payment provider takes one engineering ticket instead of three.
Hot reload and developer velocity
Flutter hot reload lets us iterate UI changes in milliseconds during development. The compounding effect across a 10-week build is real: more design iterations, more A-B prototypes, less time waiting for builds. We ship more in sprint three because sprint one moved faster.
When we do not pick Flutter
Two cases push us to native instead. Heavy AR/VR work that depends on ARKit or ARCore APIs Flutter has not yet wrapped well. And ultra-low-latency audio processing (think professional DJ apps) where every millisecond of bridge overhead matters. Outside those edges, Flutter wins on ship velocity, maintenance cost, and visual consistency. If your project lives in one of the edge cases, we will tell you on the discovery call rather than force the stack.
Flutter app development — verticals we specialise in
Food delivery and restaurant ordering
Single-restaurant ordering apps and multi-vendor aggregator marketplaces. Live-tracking, payment processing, kitchen ticket print, multi-zone routing.
Grocery delivery
Single-store and multi-store grocery platforms with the four-role workflow — customer, store, shopper-picker, admin. Inventory toggles, substitutions, slot booking.
On-demand and home services
Marketplace apps for electrician, plumber, AC repair, cleaning, beauty. Service-provider scheduling, pricing rules, location-based dispatch.
Two-sided marketplaces
Property rentals, peer-to-peer lending, freelance services. Trust and identity, escrow, calendar logic, host-and-guest dual UX.
Logistics and last-mile
Driver apps with route optimisation, proof-of-delivery, cash-on-delivery reconciliation, dispatcher dashboards.
Operator-facing dashboards
Flutter web admin panels for the operations side of any of the above. Same Dart codebase as the mobile apps; one team maintains both.
The verticals are not random. Each has a corresponding shipped product or clone in the IFA catalogue that we can show you running in production. That is the point of section 13 below — the proof that we have actually built and licensed Flutter apps in these spaces, not just listed them on a slide.
Our Flutter app development process — five client-facing stages
-
Discovery and scope
60-minute call to map the feature list, integrations, payment flows, and success metrics. You get a written scope document and fixed quote within five business days.
-
Design and prototype
Figma wireframes for every screen, then a clickable Flutter prototype on real devices. Sign-off here locks the scope before code starts.
-
Build sprints
Two-week sprints with end-of-sprint demos on TestFlight and Play Internal. You see working software every two weeks, not a slide deck.
-
QA and beta
Manual QA across an iPhone and Android device matrix, automated widget and integration tests, and a beta cohort if you want one. Bug burn-down before submission.
-
App Store and Play Store launch
Submission under your Apple Developer and Google Play Console accounts. We handle review responses; first version is live within 1 to 3 days of submit.
That is the entire client-facing sequence. No black-box phases, no "internal architecture review week" where nothing visible happens. You see working Flutter on TestFlight every two weeks from sprint one. The discovery call is free and binding only on us; we write the scope and quote whether or not you sign.
Timeline and team size for a Flutter build
The honest range, calibrated against the last several years of IFA Flutter deliveries:
- Flutter MVP (one customer app, one platform pair): 6 to 10 weeks. Team of 4 — one Flutter engineer, one backend engineer, one designer, one delivery lead. Suits a single-restaurant ordering app, a basic on-demand booking app, a content-driven app with payments.
- Multi-app product (customer + vendor + driver + admin): 12 to 16 weeks. Team of 6 — two Flutter engineers, one backend engineer, one designer, one QA, one delivery lead. Suits food delivery aggregators, multi-store grocery platforms, marketplace apps with two or three sides.
- Migration from React Native or native: 8 to 14 weeks depending on screen count and integration depth. Team of 4 to 6.
We do not staff a 12-person team on a 6-week project. Headcount inflation does not buy speed in Flutter; the bridge-free render path means most of the work is design iteration and integration testing, both of which are bottlenecked by people-count-of-one.
Tech stack we use
Flutter 3.x with Dart 3 is the foundation. Sound null safety, records and patterns, modern async streams. We pin Flutter to a specific stable channel on every project and upgrade in scheduled increments rather than chasing every release. Static analysis runs on every commit; we treat lint warnings as errors.
Backend is NestJS with MongoDB and Mongoose, plus Redis for queues, caching, and rate-limiting. Stripe handles US and EU card processing; Razorpay is the India default; Adyen for European enterprise. Mapbox or Google Maps powers delivery zones, geocoding, and live driver tracking. FCM and APNs handle push, with backend-side payload templating. CI is GitHub Actions; crash reporting is Sentry. The GetWidget UI kit (open-source, paiteq-maintained) is our default Flutter component library.
What's included with every custom Flutter build
Full Flutter source code
iOS, Android, Flutter web (if scoped), and Flutter desktop (if scoped), delivered to your Git repository.
Backend source code
NestJS APIs, MongoDB schemas, Docker-Compose for local dev, deployment notes for AWS or DigitalOcean.
Figma design files
Source components for every screen, ready for your team to extend after handover.
App Store & Play submission
Filed under your Apple Developer and Google Play Console accounts, with first-version review-response handling.
Three months of support
Bug fixes, OS-version upgrade help, store-rejection appeals, and deployment assistance included.
Documentation
README, environment-variable reference, deployment runbook, and an API endpoint catalogue.
Knowledge transfer
A 60-minute walkthrough call with your team and the engineers who actually built the app.
Monitoring wired to you
Sentry, FCM, APNs, and analytics connected to your accounts, so the data and dashboards are yours from day one.
What's NOT included — and why we name it
Most agency proposals leave the excluded list off the page. We put it on the page because the misalignments that kill projects always come from things one side assumed were "obviously" in scope and the other side assumed were obviously out.
- Apple Developer Program ($99/year) and Google Play Console ($25 one-time) enrolment. Your accounts, your credentials. We submit under them; we do not pay for them.
- Payment processor account setup. Stripe, Razorpay, and Adyen all require business documentation and underwriting. The accounts must be in your business name. We integrate the SDKs; we cannot accept payments on your behalf.
- App Store Optimisation, paid UA, and content marketing. Building the app is engineering. Acquiring users is marketing. Different specialists, different budgets. We can refer ASO partners on request.
- Vendor or supply-side recruitment for marketplaces. If you are launching a food delivery aggregator, signing the first 50 restaurants is a sales motion, not a software deliverable.
- Third-party SaaS subscriptions and per-call costs. Mapbox tier, FCM quota beyond the free tier, SendGrid, Twilio, OpenAI API calls, Stripe processing percentages — these are pass-through costs you pay vendors directly.
- Annual store fees and ongoing infrastructure cost. Apple's $99/year and Google's $25 one-time are recurring obligations. Hosting (AWS, DigitalOcean) is billed by the provider against your account.
- Compliance certification. We ship the engineering that compliance requires (tokenised payments, audit logs, account-deletion endpoints, privacy templates). Filing for HIPAA, SOC 2, or formal PCI is your operational obligation.
Putting all of this in writing on the page filters out bad-fit leads early. If any of the above is a deal-breaker, it is better learnt now than at week eight.
How much does Flutter app development cost?
Custom Flutter builds at IFA range from $18,000 for a basic single-app feature set to $80,000+ for a full multi-app marketplace with payments, dispatch, and operator dashboard. The number lands inside that range based on app count, integration count, design depth, and whether the backend is built from scratch or wired to your existing API. The three build types below are the real, current ranges — a basic single app starts at $18,000 – $30,000 and a full marketplace with multi-zone routing, a commission engine, and dispatch logic runs $55,000 – $80,000+.
One customer app on iOS and Android, with admin web and a payment processor.
- Basic to full feature set
- iOS + Android binaries
- One or multi-payment
- Full admin web
- 6 to 12 weeks
Customer + vendor + driver + admin marketplace, with payments, dispatch, and operator dashboard.
- Two to four connected apps
- Multi-zone + commission engine
- Dispatch logic
- Operator dashboard
- 10 to 16 weeks
Re-platform an existing React Native or native app onto a single Flutter codebase.
- Feature-inventory pass
- Parallel Flutter rebuild
- Same backend, cut-over release
- Requirements already done
- 8 to 14 weeks
We quote a fixed price after the discovery call. The number on the proposal is the number on the invoice. Mid-project change requests are quoted as separately-billed change orders so the original scope stays predictable. Post-launch hourly rate for new feature work is $25 per hour or available on monthly retainer. Migrating from React Native or native typically runs 60 to 80 percent of the equivalent from-scratch cost, because the requirements work is already done.
Flutter apps we've shipped — proof of delivery
Every page on this site is backed by a Flutter codebase we shipped. Every product is a real source-code package other operators have licensed and deployed; every clone-script page is a Flutter build pattern we have delivered as a custom project. That is the difference between a flutter app development company that knows Flutter and one that has actually shipped production Flutter to App Store and Google Play. Twelve concrete examples follow.
Readymade Flutter products — five live licences
Food delivery system
Multi-vendor aggregator: customer, restaurant, driver, admin web. Multi-zone routing, commission engine.
Readymade restaurant app
Branded ordering for one restaurant: customer, restaurant, admin CMS. QR dine-in, loyalty.
Readymade grocery app
Single-store grocery: customer, store, shopper-picker, admin. Substitutions, slot booking.
Multi-store grocery app
Chain and franchise grocery: every location managed from one multi-store dashboard.
Home services app
On-demand multi-service marketplace: electrician, plumber, AC, cleaner. Provider scheduling.
Flutter clone deliveries — seven build patterns we have shipped
Zomato clone app
Food delivery aggregator built for India-tone operators.
Uber Eats clone
Global food delivery marketplace pattern.
Swiggy clone app
India-first food delivery with multi-zone economics.
DoorDash clone
US-focused multi-vertical delivery marketplace.
Instacart clone
Grocery delivery with shopper-picker workflow.
Airbnb clone app
Two-sided rental marketplace, host and guest UX.
Airbnb clone script
Source-code-first Airbnb-pattern marketplace build.
For restaurant operators specifically, the restaurant ordering app pillar sits alongside the readymade restaurant product as a longer-form decision guide. Buyers of marketplace patterns frequently end up between the Airbnb clone app (full custom build) and the Airbnb clone script (source-code-first). For the platform-choice question above the Flutter layer, see our mobile app development services page.
Custom build vs readymade — when each makes sense
| ★ Custom Flutter build | Readymade Flutter product | |
|---|---|---|
| Best for | Unusual flow, novel feature set, regulated vertical, brand-defining UX | Standard food / grocery / restaurant / on-demand business model |
| Time to live | 6 – 16 weeks | Days to 6 weeks (branding pass) |
| Flexibility | Anything you can specify | What ships in the package; customisation billed at $25/hr |
| Source code | Yes, full Git repo at handover | Yes, Single Extended License |
| Backend | Built fresh or wired to your existing API | NestJS + MongoDB ships with the product |
| Risk surface | Larger — discovery defines scope | Smaller — you see the product before paying |
| Investment | $18,000 to $80,000+ | $1,500 to $5,000 |
| Ongoing support | 3 months included; hourly or retainer after | 3 months included; hourly or retainer after |
Most operators we talk to land on readymade if their model fits one of the five product categories, and on custom build if the model is novel or the regulatory surface is unusual. Either way, the source code ends up in your Git repository.
Working with us vs hire-engineers vs generic agency
Three distinct ways to get Flutter built. They are not equivalent and they do not compete on the same axis. Use this table to send yourself to the right vendor — even if that vendor is not us.
| IFA custom build (this page) | hireflutterdev.com (sister site) | Generic full-service agency | |
|---|---|---|---|
| Engagement model | Fixed-scope custom Flutter build | Engineers staffed onto your team (full-time / retainer / hourly) | Time-and-materials build, often multi-stack |
| Stack focus | Flutter only — and the readymade catalogue | Flutter only — AI-augmented engineering | Mixed: React Native, Flutter, native, web, "we can do anything" |
| Typical investment | $18,000 – $80,000+ fixed | From $18/hr — pay for the engineers, not a finished product | $30,000 – $150,000+ time-and-materials |
| Who ships the product | IFA delivery team — same people for the whole project | Your team, with their engineers embedded | Variable — often subcontracted or rotating bench |
| When this fits | You want a built-and-shipped product, fixed quote, source delivered | You have a PM and designs, you want engineers in your repo | You want one vendor for everything, willing to pay the multiplier |
| When it does not fit | Your need is staffing — go to hireflutterdev.com | You have no PM and no designs — come back to this page | You want predictable cost and a Flutter specialist |
The reason IFA and hireflutterdev.com exist as two sister companies inside the paiteq family is that the build-vs-staff decision is a real fork. Trying to be both kinds of vendor on one website tends to confuse buyers and dilute the offer. We split the brands so each can be the best version of itself.
Customisation and post-launch rate
Once the custom build is live, ongoing feature work, OS-version upgrades, and any net-new Flutter customisation is billed at $25 per hour or available as a monthly retainer at a discounted blended rate. The team that built the app is the team that extends it; nothing is handed off to a junior pool. Source code is in your Git repository, so any Flutter developer you trust can also do the work.
Frequently asked about Flutter development services
How long does it take to build a Flutter app?
Six to ten weeks for a focused MVP (one customer app on iOS and Android, payment, push, basic admin). Twelve to sixteen weeks for a multi-app product such as a marketplace or aggregator (customer, vendor, driver, admin). Inside those windows, the bottleneck is integration with third-party services, not Flutter itself. We give you a sprint-level schedule after the discovery call, not a vague range.
How much does Flutter app development cost?
Custom Flutter builds at IFA run from $18,000 for a basic single-app feature set up to $80,000+ for a full multi-app marketplace with payment, dispatch, and admin web. The exact number depends on app count (one or four), payment regions (US vs global), third-party integrations, and whether you need backend infrastructure built from scratch. We quote a fixed price after a 60-minute discovery call. No hourly contracts, no scope creep surprises.
Do I own the source code?
Yes. The full Flutter codebase, the NestJS backend, the database schema, and any custom-built admin web is delivered to a Git repository you control at handover. No license fees afterwards. No vendor lock-in. Any Flutter developer can read, extend, or fork what we build.
Do you build native bridges for camera, payments, biometrics, and other device features?
Yes. Flutter has first-party plugins for camera, photo library, biometrics, secure storage, in-app purchases, push, geolocation, and most device APIs. For features without a community plugin, we write Dart-to-native bridges in Swift (iOS) and Kotlin (Android). Stripe, Razorpay, Adyen, Apple Pay, Google Pay, and UPI are pre-wired.
Can you build the same app for web and desktop too?
Yes — Flutter compiles a single Dart codebase to iOS, Android, web (Flutter Web / WebAssembly), and desktop (Windows, macOS, Linux). The most common pattern we ship is iOS + Android + responsive Flutter web for an operator dashboard. Desktop is included on request. Flutter web development for the consumer-facing tier works best for content-heavy or operator-facing surfaces; for highly SEO-driven public sites we usually pair Flutter mobile with a separate Astro or Next.js marketing site.
Can I hire Flutter developers from you?
Not from this page — and that is intentional. We run a sister company called hireflutterdev.com that is dedicated to Flutter engineering hire (full-time, monthly retainer, project basis, AI-augmented delivery). If your need is staffing rather than a built-and-shipped product, please visit hireflutterdev.com directly. This page is for buyers who want a finished Flutter app delivered as a fixed-scope project.
Is the backend included, or do I need a separate vendor for that?
Backend is included. We ship NestJS REST or GraphQL APIs on MongoDB, with Redis for queues and caching. Hosting is your choice — AWS, DigitalOcean, GCP, or your existing infrastructure. We hand over Docker-Compose configs and deployment notes. If you already have a backend you want Flutter to consume, we wire to your existing API instead.
Can you migrate our existing React Native or native app to Flutter?
Yes. The honest playbook: a feature-inventory pass to map every screen and API call, a parallel Flutter rebuild on the same backend, then a cut-over release once parity is reached. We have done React Native, Cordova, and Ionic to Flutter migrations for operators who hit performance walls or got tired of maintaining two native codebases. Migration cost is usually 60 to 80 percent of a from-scratch build, because the requirements work is already done.
What about compliance — GDPR, HIPAA, PCI?
We ship the engineering pieces required for compliance: tokenised payments via Stripe or Razorpay (you never store raw card data), cookie consent and privacy policy templates on the web tier, account deletion and data export endpoints, audit logs. Final certification (HIPAA BAA, SOC 2, formal PCI attestation) is your operational obligation; we do not file or sign on your behalf. We do not claim out-of-the-box certification when none exists.
What does post-launch support look like?
Three months of email and ticket support is included with every custom build: bug fixes, OS-version upgrade help, store-rejection appeals. Beyond that, support is hourly at $25 per hour or available as a monthly retainer. The team that built the app stays available; you are not handed off to a junior pool. Source code is yours, so you can also bring in any Flutter developer you trust.
