App Development10 Best Flutter App Development Companies in 2026

The best Flutter app development company depends on your budget and how big a team you need. Very Good Ventures is the best-known Flutter-first firm and is priced for enterprise budgets. LeanCode, Miquido and Somnio suit companies that need a larger dedicated team at lower rates. Codigee and App369 publish starting prices, and App369 suits startups that want to work directly with the developer. Before you talk to anyone, the free app cost calculator gives you a starting budget. App369 publishes this guide and is one of the ten options. It is based on public information, not an independent benchmark.

What a Flutter app development company is (and isn’t)

A Flutter app development company builds apps with Google’s Flutter framework, usually one Dart codebase for iOS and Android, often for the web too. This guide includes firms that lead with Flutter on their own website or show public Flutter work, such as open-source Flutter packages or a Flutter app showcased by Google. Agencies that only list Flutter among many frameworks, with no public Flutter work, are left out, as are freelance marketplaces. If you’re still deciding on the framework, the Flutter vs React Native decision guide comes first.

How I compared these Flutter companies

I checked each company on October 26, 2026, using only what it publishes:

• Flutter-specific proof: open-source Flutter packages (with GitHub stars, read the same day), Flutter case studies, or a flutter.dev consultants listing.
• Published pricing: minimum project size and hourly rate on Clutch, or prices on the company’s own site.
• Track record shown publicly: Clutch rating and review count with the date read.
• Location and time zone: where the company says it is based.
• Fit: the buyer each firm’s pricing and case studies point to.

I didn’t hire these firms for a test project, review their code, or verify their own claims about team size and apps shipped. Companies are listed alphabetically. The order is not a ranking.

The best Flutter app development companies in 2026

1. App369, best for startups that want fixed prices from one Flutter developer

App369 is the studio that publishes this guide: one developer, Simon Dziak, in Miami, Florida. Flutter is his main mobile stack. He built and runs Workspace369, a Flutter app on iOS and the web with a Firebase backend, and maintains Flutter apps for clients. Prices are published: mobile apps from $9,000, web apps from $6,000, and fixed-price jobs from $450, such as a bug fix in an existing app. Simon’s Fiverr reviews (5.0 from 126, read October 13, 2026) are on the reviews page.

• Strengths: published prices and an instant quote; you work with the person writing the code; Flutter and Firebase taken over and maintained.
• Limitation: one developer, so no large parallel team and limited capacity for several big projects at once.
• Best for: founders building a Flutter MVP, or businesses with a Flutter app that needs a new developer.

2. Baseflow, best for apps that lean on device features such as camera, location and permissions

Baseflow is based in Enschede, the Netherlands, and maintains widely starred Flutter packages: on GitHub, flutter_cached_network_image has 2.6k stars, flutter-permission-handler 2.2k and flutter-geolocator 1.3k (read October 26, 2026). Its Google case study says it worked with Google for 18 months to bring 15 core Flutter plugins to enterprise-ready quality, and that Camera, In-App Purchase and WebView are now stable. It also builds full apps, with case studies for Asito and Waste Vision. Pricing isn’t published, and I found no Clutch profile.

• Strengths: plugin-level Flutter work done for Google; widely starred open-source packages; full app builds as well as plugins.
• Limitation: it says it works with clients across the Netherlands and Europe, so US buyers get little time-zone overlap, and there are no public reviews to check.
• Best for: apps where the hard part is the camera, location, payments or another native API, and teams with a plugin that has broken.

3. Codigee, best for startups that want a Flutter-focused agency with published starting prices

Codigee is based in Poznań, Poland, and describes itself as a Flutter development company. Its pricing page lists a Starter build from $5,000 and a Solid MVP from $15,000 with a one-year bug-fixing guarantee. On Clutch it lists a $10,000+ minimum project and $25–$49 per hour, with a 5.0 rating from 19 reviews and 10 to 49 employees (read October 26, 2026). Its case studies include moving the Fitatu calorie app from Cordova to Flutter and a fishing app MVP in two months, and it offers Flutter and Unity integration.

• Strengths: published starting prices on its own site; the lowest Clutch hourly rate here, tied with Walturn; migration work from other frameworks to Flutter.
• Limitation: Central European time zone, and its own $5,000 starting price sits below its $10,000 Clutch minimum, so ask what the smaller package covers.
• Best for: startups that want a small Flutter-only team, or an existing app moving to Flutter.

4. gskinner, best for design-heavy Flutter apps with custom animation

gskinner is based in Edmonton, Alberta, Canada. Its best-known Flutter work is Wonderous, an open-source app its GitHub README says was built by gskinner in partnership with the Flutter team to show Flutter’s visual fidelity, effects and transitions. The repository has 4.5k stars (read October 26, 2026). On Clutch it lists 10 to 49 employees but no reviews, rates or minimum project size, and its website doesn’t publish prices. Mountain Time overlaps most of the US working day.

• Strengths: a public example of polished Flutter UI, built with the Flutter team; North American hours; Wonderous shows polished interaction design.
• Limitation: no published pricing or reviews, and its website says little about its services, so you’ll need a call to learn scope and cost.
• Best for: brands whose app has to look and move better than a standard build.

5. Invertase, best for Flutter and Firebase tooling and SDK work

Invertase builds open-source Flutter infrastructure: its site shows the FlutterFire CLI and Melos, a tool for managing multi-package Dart and Flutter repositories, and case studies including work on FlutterFire and for Canonical. That makes it the most specialized firm here for SDKs and developer tooling rather than consumer apps. Pricing isn’t published; it offers a consultation. If your app depends on a Flutter plugin that has fallen behind iOS or Android, this is the kind of firm that maintains such plugins.

• Strengths: deep, public Flutter and Firebase engineering; well-known open-source tools.
• Limitation: focused on SDKs, plugins and maintenance more than full app builds, and its site doesn’t state a headquarters city.
• Best for: companies that need a Flutter plugin, an SDK, or Firebase integration work at the framework level.

6. LeanCode, best for scale-ups that need a large dedicated Flutter team

LeanCode is based in Warsaw, Poland, and says it has 40+ dedicated Flutter developers. Its case studies include a Flutter banking app built by about 30 developers, and it offers setup and training for Patrol, a Flutter UI-testing tool. On Clutch it lists a $25,000+ minimum project and $50–$99 per hour, with a 5.0 rating from 40 reviews (read October 26, 2026). It also offers a free scoping workshop before quoting, which is a low-cost way to compare it with other firms.

• Strengths: a large Flutter-only bench; strong testing practice; mid-range rates for that depth.
• Limitation: Central European time zone, and its case studies lean toward enterprise and banking.
• Best for: funded companies that need several Flutter developers working in parallel.

7. Miquido, best for larger companies that want an early Flutter adopter with a full-service team

Miquido is based in Kraków, Poland, and Clutch lists offices in London, Berlin, Zürich, Vienna, Amsterdam and Stockholm. Miquido’s Flutter page says its Abbey Road Studios Topline app was the first Flutter project in Europe, showcased at Google I/O 2018. Its homepage says it has 200+ experts and 15+ years in business, with client logos including Skyscanner, TUI, Dolby and HelloFresh. On Clutch it lists a $25,000+ minimum project and $50–$99 per hour, with a 4.9 rating from 51 reviews (read October 26, 2026).

• Strengths: a Flutter track record it dates to 2018; design and product work under one roof; the most Clutch reviews in this guide.
• Limitation: Flutter is one of several technologies it offers, so ask who on the Flutter side will work on your app, and the time zone is Central European.
• Best for: established companies that want Flutter plus product strategy and design from one vendor.

8. Somnio Software, best for a nearshore Flutter team close to US hours

Somnio Software is based in Montevideo, Uruguay, and calls itself the first Flutter development company in Latin America, with 95+ people. Its site says its speakers have presented at Fluttercon and other Flutter conferences, and its CTO was a guest on the Observable Flutter podcast. On Clutch it lists a $10,000+ minimum project and $50–$99 per hour, with a 5.0 rating from 46 reviews (read October 26, 2026). Uruguay’s time zone overlaps most of the US working day.

• Strengths: a $10,000 Clutch minimum, tied with Codigee for second-lowest after Walturn; nearshore hours; public Flutter community work.
• Limitation: much of its work is managed teams and staff augmentation, which suits ongoing development more than a small fixed-scope build.
• Best for: US startups that want a dedicated Flutter team in a nearby time zone.

9. Very Good Ventures, best for enterprises that want a top-tier Flutter team

Very Good Ventures says its founding team launched the first commercial Flutter app, in 2018. Clutch lists its headquarters in New York, and its Clutch description mentions offices in New York City and Chicago. Its site says it has 120+ team members globally and a 100% remote workforce. It is a Google Cloud Partner and publishes open-source Flutter developer tools. On Clutch it lists a $100,000+ minimum project and $150–$199 per hour, with a 5.0 rating from 35 reviews (read October 26, 2026). Client logos on its site include Google, Nubank, The New York Times and Toyota Connected.

• Strengths: the most recognized Flutter-first brand; large clients; widely used open-source tooling.
• Limitation: the $100,000 minimum puts it out of reach for most startups and small businesses.
• Best for: enterprises and well-funded companies building a flagship Flutter app.

10. Walturn, best for early-stage startups that want a New York-listed Flutter studio on a small budget

Walturn lists Queens, New York, says it has seven years of Flutter work, and shows Flutter case studies including Tank Payments and Labocine. It works in two-week sprints from design research to launch. On Clutch it lists a $1,000+ minimum project and $25–$49 per hour, but no reviews yet (read October 26, 2026). Clutch also lists offices in Dubai and Islamabad, so ask where the developers sit. A low minimum makes it easy to start with a small paid project before committing to a larger build.

• Strengths: a New York office; the lowest published minimum in this guide and the lowest hourly rate, tied with Codigee; a design-to-launch process.
• Limitation: no Clutch reviews yet, and its hours and project figures are self-reported, so ask for references.
• Best for: early-stage founders who want low hourly rates and a New York contact.

Which Flutter company fits your situation

How to choose a Flutter development company

1. Ask for live Flutter apps. Get App Store and Google Play links to Flutter apps the firm built and still maintains.
2. Ask who writes the code. Get names and seniority, and whether any work is subcontracted.
3. Check testing and upgrades. Ask how they test (unit, widget and integration tests) and how they handle yearly Flutter, iOS and Android upgrades.
4. Get a written scope before paying. The vendor evaluation checklist works with any firm on this list.
5. Plan for after launch. Make sure you own the code, the store accounts and the Firebase or cloud project. See App369’s Flutter development service for what a handover should include, and the free app handover checklist for the order to move each account to you.

For budgets, see Flutter app development cost and the comparisons Flutter vs Swift and Flutter vs Kotlin.
