Mobile toolkit
Flutter app development
Flutter lets one team build one app that runs on iPhone and Android, with an interface that looks the same on both. We use it for products where reaching both platforms quickly matters, and we use native code where an app needs it.

At a glance
What it is
Flutter is Google's toolkit for building apps for iPhone, Android, and the web from a single codebase, with its own drawing engine for a consistent look everywhere.
Problems it solves
Building two separate native apps doubles the cost and keeps the two versions out of step.
Who it suits
Teams launching a mobile product on both major platforms, and owners of a small team who need to reach everyone without two builds.
How to choose
Choose Flutter when you want one team and one codebase to ship to both platforms with a designed, consistent interface.
What it means
One codebase, drawn by Flutter
Flutter is an open-source toolkit from Google for building apps from a single codebase, written in the Dart language. Instead of using each phone's built-in screen parts, Flutter draws its own, so the app looks and behaves the same on every device.
That is the main difference from other cross-platform options. You get a consistent, designed interface and fast development, at the cost of an app that does not automatically take on each platform's native look.
Flutter can reach the phone's own features, such as the camera and notifications, through ready-made packages or small pieces of native code.
What DECHY can do
Working with Flutter
Build
- Apps for iPhone and Android from one codebase.
- A shared design system and component library.
Connect
- Back ends, sign-in, and payments.
- Push notifications and offline storage.
Release
- App store listings and review handling.
- Automated builds and testing.
Maintain
- Updates for new phone and Flutter versions.
- Crash reporting and improvements.
What it looks like
One codebase, one screen design, two phones
Cross-platform work succeeds when one screen design serves both platforms.
Where it fits
Flutter, React Native, or native?
These are the three routes we compare most often.
What matters most for this app?
Choose this when
Brand and interface design are central, and you want them identical everywhere.
- What you get
- Flutter, which draws everything itself and gives close control over every pixel.
- Keep in mind
- The app will not automatically follow each platform's usual look, which some users notice.
Choose this when
Your developers work in JavaScript or TypeScript and React.
- What you get
- React Native, which reuses those skills and some code.
- Keep in mind
- Its native feel depends on how each screen is built.
Choose this when
Heavy graphics, advanced camera work, or the newest platform features.
- Keep in mind
- Two codebases and a larger budget.

Designed, consistent apps for both platforms from one team.
- Trade-off
- A younger ecosystem, and a look that is Flutter's own.
Suits
Teams with web skills, and apps that should feel native.
- Trade-off
- More dependence on native modules for some features.
Suits
Apps needing the deepest platform access and best fit.
- Trade-off
- Two codebases and two teams.
Progressive web app
Suits
Simple tools used occasionally, with no store listing needed.
- Trade-off
- Limited access to phone features.
Common questions
Questions about Flutter
Is Flutter as good as a native app?
For most business apps, users will not notice a difference. For apps needing the deepest platform features or the very best fit with each system, native may be better.
Can Flutter also build a website?
It can, but we usually recommend building the website with web tools, since Flutter for the web suits some applications more than public sites.
Is it expensive to maintain?
One codebase is cheaper than two, but any app needs updates for new phone releases and dependency changes. We plan for this from the start.
Can you take over an existing Flutter app?
Yes. We review structure, dependencies, and tests first, then tell you what to improve.

Technical depth
How we build with Flutter
What we settle early on Flutter work: structure, platform features, and quality, so nothing surprises your team later.
We separate interface, business logic, and data access, choose one state management approach and use it consistently, and keep widgets small and testable.
- Maintained packages for common features, and platform channels for native code where none exists.
- Secure storage for tokens, and careful handling of permissions.
- Offline-first design for field and travel use, with sync rules for conflicts.
- Widget, unit, and integration tests, run in a pipeline on every change.
- Testing on a range of real devices, since emulators miss differences.
