Devvista is a software development and growth agency that places and manages dedicated Flutter developers for businesses in the US, UK, Australia, Canada and the UAE. You can hire a Flutter engineer by the hour, a small team for a build, or a fixed-price project, for apps that run on iOS and Android from one Dart codebase.
Flutter is, in Google's words on flutter.dev, an open-source framework for building natively compiled, multi-platform applications from a single codebase. Below: what we build, how Flutter compares with React Native, what a hire costs, how to check any Flutter developer, and how it works from your country.
What our Flutter app developers build
Business and field apps
Approval workflows, inventory and job-tracking apps for staff, with login, roles and offline use where the work happens away from a signal. These are the apps where one codebase for iOS and Android saves the most money.
Customer-facing mobile apps
Booking, ordering, membership and account apps for customers, built from a design you approve and tested on real iOS and Android devices before release.
Flutter for web and desktop
Flutter targets mobile, web, desktop and embedded devices from a single codebase, according to flutter.dev. We use that when one team should own the same product on several screens, and we say so plainly when a separate web build would serve you better.
Backend and cloud connections
Apps that talk to your own API, to Firebase, or to systems such as an ERP or CRM. A Flutter developer who also understands the backend avoids the hand-off gaps that slow most app projects. See our dedicated development teams for adding a backend developer.
Store release and maintenance
Signing, store listings, review feedback and updates after launch. A first release is the start of an app, not the end, so we plan the maintenance hours with you.
Flutter or React Native: which one should you hire for?
This is the question most buyers ask first. The table compares the two using each framework's own description, then gives our view. The right answer depends on your team and your product, not on a winner.
| Point | Flutter | React Native |
|---|---|---|
| What it is | An open-source framework for natively compiled, multi-platform apps, supported and used by Google (flutter.dev) | A way to build native apps with React, written in JavaScript |
| Language | Dart | JavaScript |
| Targets | Mobile, web, desktop and embedded from a single codebase (flutter.dev) | Android and iOS, with community projects beyond them |
| Fits a team that | Wants one UI codebase across several screens and is happy to adopt Dart | Already works in React and JavaScript and wants to reuse that skill |
| Our view | A strong choice for new apps that must look and behave the same on iOS and Android | A strong choice when the web team already knows React |
If you are weighing the two, our hire React Native developers page covers the other side, and a short call usually settles it.
What it costs and how you can hire
Devvista prices Flutter work as a fixed price from $500 to $100,000 depending on complexity, or hourly from $10 to $100 an hour depending on the type and level of developer. We quote in US dollars.
| Model | Best for | Pricing |
|---|---|---|
| Dedicated Flutter developer by the hour | Ongoing app development, maintenance and steady feature work | $10 to $100 an hour by developer level |
| Small Flutter team | A new app that needs a developer, a designer and testing together | Hourly, per person |
| Fixed-price build | A defined app with a written scope and screens | $500 to $100,000 by complexity |
| Scoping first | You know the problem but not the screens or the backend | A short engagement that produces a written spec |
Illustration (an estimate, not a quote): a business app for field staff with login, offline use and a Firebase backend, at an assumed $40 an hour:
| Work | Hours |
|---|---|
| Discovery and written spec | 20 |
| Screens built from the approved design | 80 |
| Backend and Firebase integration | 60 |
| Offline use and sync | 50 |
| Unit, widget and integration tests | 40 |
| Store submission and release setup | 30 |
| Launch and handover | 20 |
| Total | 300 hours, about $12,000 at $40 an hour |
Fewer screens or no offline use lowers the figure, and more integrations raise it. Bring your list of screens to a call and we will price your own.
Which Flutter developer profile you need
Flutter projects need different people at different stages. Matching the profile to the stage is most of the hiring decision.
| Profile | What they do | Ask to see |
|---|---|---|
| Flutter app developer | Builds screens and navigation from a design, with state management and API calls | An app they built and the state approach they chose, and why |
| Flutter architect or lead | Structures a larger app so a team can work on it, and decides the testing approach | A project structure and a test plan |
| Flutter and backend developer | Builds the app and the API or Firebase behind it | A full flow from screen to database |
| QA and release engineer | Runs device tests and handles store submissions | A release checklist and past store feedback handled |
How to check any Flutter developer before you hire
Use these questions whoever you hire, including us. A good answer is specific and names a trade-off.
- How do you manage state in this app, and why that approach? Flutter's own documentation lists setState, ValueNotifier and InheritedNotifier, and InheritedWidget as built-in options, and says the best choice depends on the app's complexity and the team's preferences.
- Which tests will you write? Flutter documents unit tests, widget tests and integration tests. Ask which of the three you will get and why, since each trades speed for confidence.
- Can I see an app on the store, and which parts did you build?
- How do you handle the first load on a slow connection, and what happens offline?
- Who owns the source code, store accounts and signing keys at handover?
- What will it cost each month to run, apart from the build, including Firebase or other cloud fees?
Be cautious of anyone who promises a start date or a result before they have seen your screens. Scope sets the timeline, and nobody controls store review.
How a Flutter hire runs
- Requirements call: your target platforms, screens, backend and timeline, followed by a written summary.
- Matching: we propose a developer for the profile you need, with the rate band that applies.
- Interview and a small paid trial task, such as one real screen with its state and a test, so you judge the work and not only the answers.
- Onboarding: access, a design handoff, a test device list and a written scope.
- Delivery and review: short stages shown on a working build, with you leading the priorities and us managing the delivery side.

Hiring from the US, UK, Australia, Canada and the UAE
Devvista works remotely with clients in all five markets and has no office in any of them. Calls, written specs and a shared project board replace site visits. If your project involves selling in several countries, the country pages cover local tax, payments and setup.
Our custom software development page covers app builds that are not on Flutter, and the Canada hub and the UK page show how we handle local rules.
Who this is for, and who it is not
| A good fit | Not a fit |
|---|---|
| A business that needs one app on iOS and Android and has a clear list of screens | A request for a guaranteed number of downloads or a fixed launch date before the scope is written |
| A team that wants to add a Flutter developer or a small Flutter team by the hour | A project that needs developers on site |
| Owners who will approve a written spec and review work in stages | A simple web page, which a website builder or WordPress would serve at a lower cost |
