Flutter app development: one codebase, both app stores
Flutter app development means building one app in Dart that runs on both iPhone and Android, with the same design on each. Hostlyx uses Flutter when an app is mostly screens, forms, data and payments, so you maintain one codebase instead of two. We also build and host the backend and admin panel, and quote a fixed price before work starts.
Flutter is Google's toolkit for building apps for iOS and Android from a single codebase written in Dart. Flutter draws every pixel itself, so the app looks the same on both platforms and custom, brand-led designs are straightforward to build. One team writes one set of features, and both stores get them at the same time.
Flutter fits most business apps well: booking, ordering, loyalty, customer portals, delivery tracking and internal tools. It is less suited to apps that lean heavily on brand new platform features or very specialised hardware, where native Swift and Kotlin still win. We tell you honestly which side of that line your app falls on.
Because there is one codebase, later changes cost less too. A new feature, a bug fix or a design refresh is made once and shipped to both stores, which keeps the running cost of the app lower over its life. It also means one set of tests, one release process and one team who knows the code, rather than two groups who may drift apart.
What is included
One Dart codebase
A single Flutter project in Dart that produces both the iOS and Android apps, organised with clear state management so it stays readable as features grow.
Custom branded interface
Your brand's type, colour and motion rendered identically on iPhone and Android, with platform touches such as back gestures and scrolling behaviour kept natural.
Native features through plugins
Camera, maps, payments, push notifications and biometrics added through well-maintained plugins, with native Swift or Kotlin code written where no good plugin exists.
Release to both stores
Signed builds, store listings and submission to the App Store and Google Play under your accounts, with releases kept in step across both platforms.
Backend, admin and hosting
The API, database and admin panel the app depends on, built and hosted by the same team, so app and server changes ship together.
Flutter upgrades
Flutter and its plugins move quickly. We keep the SDK and dependencies up to date so builds keep passing the latest store requirements.
Tools and platforms: Flutter, Dart, Riverpod, Bloc, Firebase, Xcode, Android Studio, Laravel, Node.js, PostgreSQL

How we work
-
Check the fit
We review your features against what Flutter does well and confirm it suits your app, or recommend native if it does not.
-
Fixed written quote
You receive a written quote listing the screens, plugins and backend work included, so cost and scope are agreed up front.
-
Design once
One set of screen designs serves both platforms, with small platform-specific touches noted where iPhone and Android users expect different behaviour.
-
Build and test
We build in Flutter and test on real iPhones and Android phones, sharing builds through TestFlight and Play Console testing tracks.
-
Launch and maintain
Both stores receive the release together. Afterwards we fix issues, upgrade Flutter and plugins, and quote new features as you need them.

Questions people ask
How much does Flutter app development cost?
Cost depends on the number of screens, how custom the design is, the native features needed, and the backend and admin panel. Flutter usually costs less than two native apps because features are built once. After a scoping call we send a fixed written quote listing everything included.
Is Flutter better than native iOS and Android development?
Neither is better everywhere. Flutter is the economical choice for most business apps that need both stores. Native Swift and Kotlin are better for apps that depend on the newest platform features, heavy background work or specialised hardware. We tell you which suits your app after scoping.
Flutter or React Native: which should I choose?
Both build iOS and Android apps from one codebase. Flutter suits highly custom, brand-led designs and teams starting fresh. React Native suits companies that already have a React web app and JavaScript or TypeScript developers. We recommend one based on your design, team and existing code.
Can a Flutter app use the camera, payments and push notifications?
Yes. Flutter has mature plugins for the camera, maps, biometrics, push notifications and payment providers such as Razorpay and Stripe. Where no reliable plugin exists, we write a small piece of native Swift or Kotlin and connect it to the Flutter app.
Do I own the code of my Flutter app?
Yes. The Flutter source code, designs and store listings belong to you, and both apps are published under your own Apple and Google developer accounts. We hand over the repository, so any Flutter developer can pick up the project later.
