Flutter app development

One codebase, two stores, one release day.

Flutter is the right answer more often than purists admit and less often than agencies claim. We start every engagement by telling you which case you are in โ€” then build accordingly.

How a project runs
  • Senior engineers only
  • NDA before day one
  • You own the code
  • Both stores, one pipeline

Where it fits

Four products Flutter suits well

Open the one closest to yours โ€” the architecture decisions differ more than the screens do.

Mobile product screens on several devices Product apps

Both stores, one team, same release day.

Consumer products where the screens matter more than the platform, and shipping Android and iOS together is worth more than per-platform polish.

  • Shared UI and business logic
  • One release train
  • Design system in widgets
  • Platform tweaks where they matter
A team working on an internal application Internal tools

Field, floor and back-office apps.

Tools for your own staff, where the user base is known, the devices are known, and speed of change beats platform-native feel.

  • Offline-first data capture
  • Barcode and peripheral support
  • Private distribution
  • Rapid iteration

Early products that need to be in real hands on both platforms before the architecture deserves an opinion.

  • Thin vertical slices
  • Instrumented from day one
  • Feature flags
  • Cheap to change

The same app on a tablet, desktop or kiosk.

Where one Flutter codebase also covers a desktop tool or a kiosk screen, with layouts that adapt rather than scale.

  • Adaptive layouts
  • Desktop and web targets
  • Kiosk and lock-down modes
  • Shared design tokens
What we build

Six decisions that keep a Flutter app healthy

Most struggling Flutter codebases we inherit got three of these wrong.

A design system in widgets

Your brand expressed once as components, so screens stay consistent and a rebrand is a token change rather than a sweep.

  • Tokens for colour and type
  • Composable widgets
  • Golden tests on components

State management that scales

One state approach chosen deliberately โ€” Riverpod or Bloc โ€” applied consistently instead of three patterns fighting.

  • Riverpod or Bloc
  • Clear data flow
  • Testable view models

Native where it counts

Platform channels for the capabilities Flutter doesn't cover natively, written and owned by us rather than relying on an abandoned package.

  • Platform channels
  • Vetted plugin choices
  • Native fallbacks

Device capabilities

Camera, Bluetooth, location and background work tested on both platforms, because this is where cross-platform projects usually stall.

  • Camera and scanning
  • BLE peripherals
  • Background location

Performance discipline

Jank profiling, list virtualisation and image handling, with frame budgets watched on the lowest device you support.

  • Frame timeline profiling
  • Lazy lists and caching
  • Startup budget

Two stores, one pipeline

A single CI pipeline that signs, builds and ships to Play and TestFlight so a release is one action, not two rituals.

  • Shared CI pipeline
  • Signed artefacts both stores
  • Staged / phased rollout
When not to use it

Four cases where we recommend native instead

We build native apps too, so we have no reason to push you into the wrong toolkit. These are the cases where we say no to Flutter.

Heavy platform integration

Deep widgets, Live Activities, CarPlay, complex watch apps and tight OS-level integrations are still cleaner native.

Graphics-heavy or AR products

If the product is a 3D or AR experience, build it on the engine made for that rather than fighting a UI toolkit.

A team that only knows native

Technology choice should match who maintains it. If your team is Kotlin and Swift, Flutter adds a dependency on us โ€” and we will say so.

One platform, forever

If you will only ever ship iOS, native is simpler. Cross-platform earns its keep when both stores matter.

The fit review

Thirty minutes, a senior engineer, and a straight answer: Flutter, native, or one of each. If the honest answer is native, the proposal quotes native.

So you always know what happens next, what it costs and when you'll hold a build.

01

Fit review

A free 30-minute call with a senior engineer, including an honest answer on whether Flutter is right for this product.

02

Fixed-scope proposal

Screens, native integrations, device matrix, timeline and cost in writing within 5 business days.

03

Build in the open

Short cycles with installable Android and iOS builds every week from the same codebase.

04

Launch and look after it

Both stores, staged rollout, crash monitoring, and the same team shipping the next version.

FAQ

Questions about Flutter projects

Still unsure? Ask us directly โ€” a senior engineer replies within one business day.

For most product apps, yes โ€” Flutter draws its own widgets, so the look is consistent and can follow either platform's conventions. Where an app leans on platform-specific UI (widgets, Live Activities, deep system sheets), native is still the better fit, and we say so during the fit review.
