Hire Flutter developers
iOS + Android, Firebase, store releases
Flutter engineers who ship to both stores from one codebase, and who have been through app review often enough to know what gets an app rejected before it is submitted.
Cross-platform is a cost decision, and it only pays off if the engineer knows where the platform boundaries genuinely sit. Flutter gives you one codebase for iOS and Android. It does not save you from App Store review, from Android's background execution limits, or from the day somebody needs a native module for a payment terminal.
Our Flutter engineers have shipped to both stores repeatedly, which is a different qualification from having built one app once. They use Riverpod or Bloc depending on what your team can maintain after we leave, keep business logic out of widgets, and write widget and integration tests so a release does not rest on somebody remembering to tap every screen. The release plumbing is theirs too: signing, provisioning, TestFlight, Play internal testing, staged rollouts, and Crashlytics wired up before launch rather than after the first angry review.
Firebase turns up on most of these projects, Auth, Firestore, Cloud Functions, Remote Config, push. Where a client already has a REST or GraphQL backend they consume that instead, and they make offline behaviour a decision rather than an accident.
When a dedicated Flutter developer is the right call. The same app has to exist on both stores, on one budget and one roadmap. You have a Flutter app and the original developer has vanished. You are building something interface-heavy, booking, ordering, field capture, membership, where custom design matters more than deep platform integration.
When it is not. ARKit, complex Bluetooth, background audio or heavy on-device processing all point at native engineers, and we will send you there. And if what you are describing is really a mobile website, a responsive build costs a fraction and skips app review altogether.
Every engagement includes store setup and a release process your own team can repeat without calling us.
What they do
Cross-platform apps
iOS and Android from one Flutter codebase: custom design, animation, deep links, localisation and dark mode from the first sprint.
Firebase and backends
Auth, Firestore, Cloud Functions, Remote Config and push, or your own REST and GraphQL API behind typed generated models.
Offline and sync
Local persistence with Isar, Drift or Hive, conflict handling, and an explicit answer for what the app does on a train with no signal.
Store releases
Signing, provisioning, TestFlight and Play internal tracks, staged rollouts, and the privacy declarations that decide whether review passes.
Native integration
Platform channels and plugins for the things Flutter alone will not do: payments, biometrics, camera, Bluetooth, background tasks.
Taking over an app
Inherited Flutter codebases audited, brought onto a current SDK, dependency debt cleared, and releases made repeatable.

How to hire
Tell us what the app does offlineDay 0
That one question shapes the architecture more than anything else. Add the hardware it touches, the stores you publish to, and your target date.
Profiles with apps you can download48 h
Two or three CVs with live store links, not screenshots. Install them, use them on your own phone. Rate, availability and whether native work looks likely, in the same message.
Interview and check the store history2–4 days
Ask about the last rejection they handled and what fixed it. Set a live task if you like. Nothing is billed and no profile gets pushed at you.
A build on your phone in two weeksDays 1–15
TestFlight or the Play internal track, running a real feature from your backlog. You judge the app in your hand rather than a plan in a document. Stop any time, unbilled.
Releases you can repeatOngoing
NDA and IP before the first commit, your developer accounts with minimum access, and a documented release process your own team can run. Pause on 30 days' notice.
FAQ
Flutter or React Native, which should we choose?
Flutter if the design is custom and you want identical results on both platforms, since it renders everything itself. React Native if your web team already writes React and you want to share people and libraries. Both are legitimate. We will ask what your team looks like before answering.
Will one Flutter developer really cover iOS and Android?
For most apps, yes. Budget a little native help for platform-specific work like payments, biometrics or deep background tasks, and expect separate testing on real devices for each platform. Device testing is included in the engagement rather than assumed away.
Can they publish to the App Store and Play under our account?
Yes, and it is how we prefer to work, because the apps should stay yours. The engineer works inside your Apple Developer and Play Console accounts with the minimum access needed, and sets up a release process your team can run without us.
What about App Store rejections?
They happen, usually over privacy declarations, sign-in requirements or metadata rather than code. Our engineers have been through review dozens of times and prepare those answers before the first submission, which is exactly where first-timers lose a fortnight.
Can they take over an app we already have?
Yes. Week one is an audit: SDK and dependency versions, architecture, test coverage, release process, crash rate, and a written list of what to fix in what order. That document is yours to act on even if you stop there.

No retainer to see CVs, and no invoice until the trial ends and you say yes.
