Modern Dart
Dart 3 with sound null safety, records, patterns and sealed classes — code that catches mistakes at compile time rather than in a one-star review.
Hire Flutter developers · UK
One Dart codebase for iOS and Android, built by Flutter developers who still know what each platform expects — from permission prompts to store review.
Flutter expertise
Flutter developers who write idiomatic Dart, keep widget trees lean, and drop into Swift or Kotlin when a plugin does not exist.
Dart 3 with sound null safety, records, patterns and sealed classes — code that catches mistakes at compile time rather than in a one-star review.
Riverpod or Bloc, chosen for your team and your app, with clear lines between UI, state and data so new features do not tangle old ones.
Method channels, Pigeon and Dart FFI to reach native SDKs for payments, Bluetooth or biometrics — and custom plugins when pub.dev has nothing reliable.
Profiling in Flutter DevTools, cutting needless rebuilds, lazy lists and image caching, so scrolling stays smooth on older phones as well as new ones.
Build flavours for development, staging and production, code signing, TestFlight and Play testing tracks, and automated pipelines with Codemagic or Fastlane.
Your brand as a theme and a widget library, with Material or Cupertino behaviour where users expect each platform to feel familiar.
What they build
The Flutter projects UK teams bring us most — often where one small team has to serve both app stores.
One codebase, both stores: onboarding, accounts, payments and analytics, planned over weeks rather than months so you learn from real users sooner.
Menus, baskets, loyalty cards and push offers connected to your till or eCommerce platform, with Apple Pay and Google Pay at checkout.
Inspections, job sheets and proof-of-delivery apps that save work on the device, sync when signal returns, and capture photos and signatures.
Build new features in Flutter inside an existing iOS or Android app and move across gradually, instead of pausing everything for a rewrite.
Where it makes sense, the same Flutter code runs as a web app or a Windows or macOS desktop app for staff — not for public, search-driven sites.
Bring an app written for older Flutter and Dart releases up to date: null safety, abandoned plugins, Gradle and Xcode changes, and current store rules.
Technology stack

Release and monitoring
Developer seniority
Every engagement is staffed with senior engineers. What changes is how much architecture and leadership the work needs around them.
Takes features from ticket to reviewed, tested, deployed code without hand-holding. The right choice for most roadmap work.
Sets the Flutter architecture, reviews the team's code and plans migrations, upgrades and scaling work.
A Flutter developer with backend, QA or design support, coordinated by one delivery owner for larger scopes.
Engagement models
Pay by the hour for bursts of work, reserve a dedicated developer for your roadmap, or hand us the whole project.

Ongoing delivery, product teams, and roadmap acceleration
Fixed quote
MVPs, rebuilds, dashboards, SaaS platforms, and business-critical launches
Prices are in GBP. Every estimate is confirmed in writing after a discovery call — the figures above are where engagements start, not a quote.
How hiring works
The goal is not just to introduce a Flutter developer — it is to make the first week useful and the work visible from then on.
We review your Flutter goals, current stack, deadlines, risks, and success metrics before suggesting an engagement model.
Role and success criteria agreed
You get a clear Flutter developer profile, relevant experience, availability, and estimated weekly capacity.
Developer profiles to review
We agree priorities, access, communication rhythm, delivery milestones, and code review expectations. Most engagements start within 5–7 working days of sign-off.
Access, rituals and first tickets
Every week you see working Flutter progress, blockers, next steps, and measurable delivery against the plan.
Visible progress every week
Why Techsleight
What you can hold us to — and what happens if something is not working.
You see profiles and talk to the Flutter developer before anything starts, and nobody joins your team without your say-so.
People who have shipped and supported real products — reviewed for code quality, testing habits and communication, not just a CV.
Your repositories, tickets, stand-ups and review rules. Daily written updates and a weekly demo keep the work visible.
Hourly, dedicated or project-based, with short notice periods. Scale up for a launch and back down after it.
Code, IP and documentation belong to you from day one. NDA before any detailed conversation, if you need one.
UK business hours, GBP pricing and a contract with a UK company. Our engineers are based in the UK and India.
Backend, QA, DevOps and design colleagues are there when the Flutter work needs them — without you hiring for each role.
Relevant work
We do not have a published Flutter case study yet — these show the kind of product work our engineers join.
All case studiesMobile-first money transfer and card app for a cross-border fintech.
Fitness app for workouts, nutrition logging and progress tracking.
Online pharmacy and lab-test booking app with prescriptions and delivery.
FAQs
Straight answers on scope, cost, timelines and how we work. If yours is not here, ask us directly.
Both are sound choices. Flutter draws its own UI, so screens look the same on every device and complex animation is straightforward; React Native renders native components and suits teams that already write React and TypeScript. We weigh your existing skills, the native SDKs you need and who maintains the app after launch, then recommend one.
For most business and consumer apps, users will not notice a difference: release builds compile to native machine code and Flutter renders with its own engine. It can fall short on heavy platform-specific work — advanced camera pipelines, AR, deep OS integrations — and there we write that part natively and call it from Flutter.
It can, and Flutter web works well for app-like tools behind a login. For public pages that need to rank in search and load instantly, a web framework such as Next.js is the better choice, with the same APIs behind both. We will tell you which parts of your product belong where.
We can. We set up signing, build flavours, store listings, privacy labels and Google Play’s Data safety form, then automate builds so a release is a tagged commit rather than a day of manual steps. Your organisation owns the developer accounts; we work inside them.
Flutter developer rates at Techsleight Labs start from £23/hour for flexible work and from £3,300/month for dedicated monthly capacity. Fixed-price Flutter projects are quoted after discovery, once scope, integrations, risks, and timeline are clear.
Most Flutter engagements start within 5–7 working days of sign-off, and urgent work can sometimes start within 48–72 hours. For larger projects, we first confirm scope, architecture, milestones, and the right senior engineer fit before kickoff. We support UK teams with written updates, planned demos, and timezone-aware handover.
Yes. You can hire a single Flutter developer, add a small pod with QA and DevOps, or ask us to manage the complete project. We match the model to your current team, delivery pressure, and budget.
Yes. Our hiring pages are built around senior production engineers, not junior bench resources. Every developer is reviewed for commercial project experience, communication quality, code quality, testing habits, and ability to work inside existing teams.
Yes. We often join existing Flutter projects to fix performance, unblock releases, add features, improve test coverage, or modernise architecture. We start with a codebase review so the first sprint is practical rather than theoretical.
Tell us early. We will look at the cause with you — the brief, the onboarding or the match — and agree the next step together, such as more technical oversight, a different engagement model, or ending the engagement on the notice terms in your contract. The goal is a useful working relationship, not lock-in.
