Flutter developers with apps in forty thousand pockets.
Hiring Flutter developers from CODT Technologies gets you a senior mobile team whose Flutter work is already in production: the FeelEat app that unlocks connected fridges for 40K+ users, attendee apps for Bizzabo’s event platform, and RushTix’s ticketed live shows — one codebase per product, iOS and Android from day one. The FeelEat app is itself a migration story: its first generation shipped as native iOS and Android WebView shells, and in 2023 the same team rebuilt it in Flutter — we have lived both sides of that decision.
One codebase, two stores, zero handovers.
A paid discovery sprint
One week mapping user journeys, device integrations and the offline states that sink app projects when discovered late — including an honest answer on whether Flutter is the right tool for your product at all.
A fixed, transparent quote
The fixed-scope estimate comes after the discovery sprint, grounded in your actual app rather than a template. Cost and timeline are agreed before development starts — no open-ended hourly billing.
A senior Flutter team ships every two weeks
Two-week iterations against a shared TestFlight and internal track — one Flutter codebase producing both the iOS and Android builds, with the backend API evolving alongside it under the same roof.
Launch, store submission and ongoing care
We run the store-submission pipeline for both stores, phase the rollout, and stay on afterwards for SDK upgrades, OS-version compatibility and feature evolution — by the engineers who built the app.
Everything a Flutter release needs, under one roof.
Flutter & cross-platform engineering
Flutter chosen on engineering merit, not fashion — one codebase where it serves the business, native Swift and Kotlin where the product demands it. We build both and argue the choice with evidence.
Mobile app development →UI / UX design
Research-led design shipped under engineering scrutiny — user journeys, prototyped flows and a design system your Flutter widgets actually implement.
UI / UX design →Connected hardware & IoT
Flutter apps that talk to physical fleets — the FeelEat app unlocks connected fridges and charges on door close, over live MQTT telemetry from every unit.
IoT solutions →The backend behind the app
The API, authentication, payments and telemetry your Flutter app talks to — engineered by the same team, so the seam between app and server never becomes a blame line.
SaaS app development →Flutter apps that run real businesses.
FeelEat Happy Fridge — a Flutter app that runs a shop
FeelEat’s mobile app — built in Flutter on a Node.js and NestJS backend — is the menu, the key and the checkout for a fleet of connected fridges: browse the daily menu, scan to unlock, take your meal and get charged on door close. Forty thousand downloads later, it carries a Swiss unmanned-retail business valued at $10M+.
Bizzabo & RushTix — Flutter where the audience lives
For Bizzabo’s Event Experience OS we shipped the Flutter attendee apps alongside the React web surfaces — mobile front doors to broadcasts peaking above 50K concurrent viewers. For RushTix, Flutter mobile and React web share one GraphQL API, putting ticketed live comedy in the audience’s pocket with a 2.4-second median join.
Questions teams ask before hiring Flutter developers
Coloque-o num briefing. Um engenheiro sénior — não um vendedor — responde no prazo de um dia útil.
Q.01Which production apps has CODT built with Flutter?
Named and linked on this page: the FeelEat Happy Fridge app (scan-to-unlock retail, 40K+ downloads), the Flutter attendee apps for Bizzabo’s event platform, and RushTix’s mobile app for ticketed live shows — Flutter mobile and React web sharing one GraphQL API.
Q.02Flutter or React Native — which should we choose?
React Native if your team already knows React and TypeScript and you want to share logic with a web app — the ecosystem and hiring pool are larger. Flutter if you want pixel-identical UI across platforms and don’t mind Dart. Both are production-ready; we let your existing skills and any web-code-sharing opportunity decide, not hype. We ship both.
Q.03When would you tell us not to use Flutter?
When the evidence points elsewhere — heavy platform integration, camera or background work, or a single-platform audience favours native. We have made that call against cross-platform on our own projects: FeelEat’s workforce app went native iOS and Android because the product demanded it. You get the recommendation with reasons, per project, not per dogma.
Q.04Can a Flutter app talk to hardware?
Ours already do. The FeelEat app is the key to a physical fridge fleet — scan-to-unlock sessions, charge on door close — running over live MQTT telemetry from every unit. Flutter sits alongside NFC, BLE and embedded work in our IoT practice.
Q.05Do you handle App Store and Play Store submission?
Yes — metadata, screenshots, privacy labels, age ratings and review responses for both stores, with pre-flight checks against Apple’s guidelines and working review accounts supplied. One Flutter codebase, two store pipelines, one team accountable for both.
Q.06Who owns the app and its code?
You do — 100%. The Flutter codebase, the designs and the intellectual property transfer to you at delivery; we keep a copy for support purposes only with your written permission. An NDA on request is standard.
Q.07How fast can Flutter developers start, and what happens after launch?
A senior engineer replies to your enquiry within one business day, and the engagement opens with a one-week discovery sprint. After launch, every engagement includes a 30-day operate window with the team on call; most clients then extend on a retainer for feature evolution and OS-version compatibility — with the same engineers.
