Hire Flutter developers to build one app for iOS and Android.

For teams that need mobile capacity without a hiring round. A named Flutter engineer joins your repo and your review process, builds the app you have already scoped, and can stay on afterwards to keep it running on both stores.

What they do

What a Flutter Developer from infoloop actually builds.

One codebase, two stores

One Flutter codebase that builds to iOS and Android, with platform differences handled where they matter rather than papered over. Navigation, permissions and share sheets should feel native on each one.

Native platform integration

Camera, location, push notifications, biometrics, background work and offline storage, wired through platform channels where a plugin does not exist. We write the Swift or Kotlin side when it is needed.

State management and offline behaviour

A state approach chosen for the app rather than the fashion, with data that survives a lost connection, a backgrounded app and a cold start. Sync and conflict rules written down, not left to chance.

Backend, API and CMS integration

The app talking to your existing APIs, or to a Strapi or Webflow CMS where content needs to change without a release. Caching, retries and error states decided per screen, not handled globally by accident.

Release, signing and store submission

Build flavours, signing keys, versioning, TestFlight and Play internal testing, plus the store listings and privacy declarations that hold submissions up. Set up once so your team can release without us.

AI features inside the app

Assistants that behave on a phone: tokens streaming into a widget without dropping frames, tool calls the user can watch and cancel, and plain wording when a request dies mid-answer on a weak signal or the model declines.

How it runs

Plan. Build. Run.

01

A 30 minute call

Bring the screens you have in mind, the devices your users actually hold, and any date the stores have to see it by. We ask about the API behind it, who owns the designs, and whether the developer accounts exist yet.

02

What gets built, and for what

The screens, the device features, the order they arrive in, the date and the figure, all in writing. If it is really a seat on your team rather than a defined app, we say so and quote a monthly rate per engineer.

03

Meet them, then a throwaway build

You meet the engineer before anything is signed, and you can say no. They take repository and console access, then push something trivial all the way to TestFlight and Play internal testing, so signing and distribution are proven before real features depend on them.

04

Build, submit, then run

Work lands in your sprint as reviewable pull requests with a written note each week on what shipped and what is stuck. Then submission, review, any rejection answered and resubmitted, and a staged rollout. After that, handover or retainer.

Why infoloop

We do not hand over and leave.

  • The stores keep moving after you stopEvery year brings a new iOS and Android version, a raised minimum SDK and store policy edits that reject an app which submitted fine last quarter. Our run retainer absorbs that, and gets the next build through review.
  • The figure is settled before the first commitWhat the app has to do, in what order, by when and for how much, written down before the engineer opens an editor. Add a screen or a device feature halfway through and it is quoted on its own for you to approve.
  • We build inside your accounts, not oursYour repository, your branching model, your Apple and Google consoles, your CI lanes. Builds are submitted under your organisation, so release history, tester groups and crash data accumulate somewhere you keep.
  • A rollback plan that suits a storeYou cannot pull a bad phone build the way you pull a bad deploy. So: staged rollout on Play, phased release on the App Store, crashes split by platform and OS version, and remote flags on anything worth switching off without a resubmission.
  • You meet the engineer before you commitThe person who would write the Dart is on the call, not a sales lead describing them, and you can turn them down. Whoever takes it leaves their reasoning in the repository, so the widget structure and the sync rules stay legible.

What you get

Every engagement includes these, in writing, before work starts.

  • A named Flutter engineer in your repo, tracker and standup.
  • One codebase producing signed iOS and Android builds each release.
  • Signing, build flavours and store submission set up in your accounts.
  • Crash reporting and release monitoring live before launch day.
  • Tests on the flows you cannot afford to break, running in your CI.
  • A written weekly update: shipped, in progress, blocked, and what we need.

Who this is for

Three situations where this is the right call.

You need one app, not two teams

The product has to be in both stores and funding a native team for each is not realistic. One codebase, one backlog, one engineer answerable for both builds. Because Flutter draws its own widgets rather than borrowing the platform's, the two apps stay the same screen instead of drifting into two designs nobody signed off.

The work happens away from a desk

Your people are in a van, a warehouse or a ward, and a browser tab on a laptop does not reach them. What is wanted is a phone app that scans a code, takes a photo, knows where it is, keeps working through a dead signal, and reconciles with the systems you already run once the signal comes back.

The build is broken and the author is gone

The Flutter version is years behind, several plugins are unmaintained, nobody left can produce a signed release, and Apple or Google are sending deadline notices about minimum SDK levels. You want it dragged forward in reviewed steps, documented on the way, rather than argued into a rewrite.

Questions

What buyers ask us first.

What does it cost to hire a Flutter developer through infoloop?
There is no rate card on this page, because the figure moves with seniority and with how much of the app the engineer owns end to end. What we commit to is the shape instead. Half an hour on a call, then a written scope with a date and a figure against it, agreed before any Dart is written. An engineer sitting inside your team month to month is billed per person per month. A defined build, say a first signed release in both stores, is quoted as one piece of work, and the run retainer afterwards is optional and separate. Anything added later is quoted on its own and approved by you first.
How quickly can a Flutter engineer start, and what do you need from us?
The date is settled while we are scoping and written next to the scope, so it is a commitment rather than an aspiration. What genuinely shortens the ramp sits on your side: repository access, the design files, API documentation you trust, one person who can settle a question the same day, and Apple Developer and Google Play organisations already in your company's name with the engineer invited into them. Where those consoles do not exist yet, enrolment and verification take their own time before any build can reach a tester. We push a throwaway change through TestFlight and Play internal testing in the first week, because signing and distribution are where phone projects lose time, and it is better to discover that on a build nobody cares about.
Is Flutter the right choice, or should we build native?
Flutter draws its own widgets with its own rendering engine rather than borrowing the platform's, and most of the answer follows from that. The gain is that a screen looks the same in both stores and stays that way when Apple or Google restyle their controls, and one person can hold the whole product in their head. The cost is that anything the engine does not draw, such as home screen widgets, deep system pickers, or watch and TV surfaces, has to be reached through platform channels and written in Swift or Kotlin. So it fits products with their own design language and a lot of shared logic. It fits badly where the app is mostly a thin skin over platform features or leans on on-device machine learning. We will say on the call if native or React Native is the better answer, and we would rather lose the work than build the wrong thing.
Will the engineer work in our repo and follow our process?
Yes. They commit to your repository, follow your branching model, take tickets off your board, and wait on your approvers like anybody else. Phone work adds a few things worth agreeing in the first week, so we agree them: which build flavours exist, who holds the signing keys, what goes into release notes, and who actually presses submit. If you keep an architecture note, a lint setup or a widget catalogue, we read those first and build to them. If none of that exists, we write down what we assumed and leave it beside the code rather than carrying it around in one person's head.
What happens after the app is in the stores?
Two routes, and you pick before submission rather than after. Either your own team takes it on, with a walkthrough, the signing material, the release steps and a list of what we left unfinished, or the run retainer continues and we stay the ones who cut releases. What makes phones different from the web is the release train. You cannot patch a build the way you patch a site, a fix needs a review cycle before it reaches anyone, and older versions stay installed on real devices for months afterwards. Somebody has to watch which versions people are running, and keep the app buildable against the next iOS and Android before a store deadline forces it.
Do we own the code, the accounts and the release keys?
All three, and the accounts matter more than people expect. The code sits in your repository under your licence from the first commit, plain Flutter with no wrapper of ours around it. The Apple Developer and Google Play organisations are enrolled in your company's name and we work inside them as invited members, so listings, ratings, reviews and tester groups belong to you rather than travelling with us when we go. Signing certificates and the Play upload key live where your own team can reach them, with the recovery path written down, because a lost upload key is a genuinely painful thing to unpick. End the engagement tomorrow and your next release still goes out.
