Flutter lets you ship an iOS and Android application from a single codebase, with fluid interfaces and real design freedom. We use it for consumer apps as well as business tools, and we walk you through to publication on the App Store and Google Play. Adhaniya, our prayer times app on Android, is built with Flutter.

## What we do

### One app, two platforms

iOS and Android from the same Dart code, with Material and Cupertino components: half the budget, perfect consistency across both stores.

### Polished, animated interfaces

Flutter draws every pixel itself: 60 fps animations, a design system faithful to your mockups, light and dark themes.

### Offline, notifications, sensors

Synchronised local database, push notifications, geolocation, camera, home-screen widgets: native features, reachable from Flutter.

### Publication and follow-up

Developer accounts, store listings, screenshots, compliance with Apple and Google guidelines, CI/CD with Codemagic, monitoring of feedback after launch.

## What Flutter does better

Flutter does not rely on each system's native components: it ships its own rendering engine. That is what guarantees identical rendering on iOS and Android, fluid animations and complete design freedom. The trade-off is an app slightly heavier than a native one, which is irrelevant for almost every project.

## How we run a mobile project

[Mockups and flows](https://eldev.fr/en/services/ui-ux-design/index.md) validated before the first line of code, then iterative development with test builds distributed to your phones (TestFlight, Play Internal Testing). Every screen is tested across several screen sizes and OS versions. At delivery: Git repository, build pipeline, documentation of accounts and keys, and a [maintenance](https://eldev.fr/en/services/maintenance/index.md) plan to keep up with iOS and Android changes.

## Stack & tools

Flutter, Dart, Riverpod, Drift / SQLite, Firebase, Supabase, Codemagic, Fastlane, Sentry, App Store Connect, Google Play Console

## Why ELDEV

We build and publish Flutter apps in production, including our own. We know the tricky parts: state management, list performance, iOS permissions, screen sizes, SDK updates. You get an application tested on real devices, a documented Git repository, and a single point of contact from scoping to publication, then for updates.

## Frequently asked questions

### Flutter or React Native?

Flutter when the interface is highly graphical, animated or must be pixel-identical on both platforms; [React Native](https://eldev.fr/en/technologies/react-native/index.md) when your team is already on React and wants to share code with the web. Both produce excellent apps; we advise you at scoping.

### Can the app work without a connection?

Yes. We store data locally (SQLite) and synchronise as soon as the network returns, with conflict handling. It is essential for field, logistics or [healthcare](https://eldev.fr/en/sectors/healthcare/index.md) apps.

### How much does a Flutter application cost?

It depends on the number of screens, native features, [back-end API](https://eldev.fr/en/technologies/nodejs/index.md) and back-office. A well-scoped MVP ships in 6 to 10 weeks. Quote after a free scoping call: [get in touch](https://eldev.fr/en/contact/index.md), reply within 12 hours.

### Who handles store publication?

We do: creating or configuring your Apple and Google accounts, listings, screenshots, submission, review feedback. See our [mobile apps](https://eldev.fr/en/services/mobile-apps/index.md) service.
