[ADVANTAGES OF FLUTTER FOR BUSINESS]

Why do leading brands (BMW, Alibaba, eBay) choose Flutter

Technology that combines flexibility of designer solutions with the highest productivity on the market

[ 01 ]

Smooth 120 FPS without 'stuttering'

Unlike systems that use intermediaries to native elements, Flutter paints each pixel independently through the device's graphical API.

[ 02 ]

100% compliance with the corporate style of the brand

There are no limitations on standard iOS or Android buttons. Any boldest designer idea can be implemented without compromises.

[ 03 ]

Quick expansion to tablets, Web, and desktop

Dart code can be easily compiled into a web version or a desktop application for Windows and macOS.

[ 04 ]

Direct compilation to machine code (AOT)

The source code before publication is compiled into ARM machine code, which significantly complicates decompilation and reverse engineering by malicious actors.

[ Stages of Flutter App Development ]

What is included in the development of a Flutter app under license

Individual engineering process from UI-kit to Figma to passing the review in markets

[ STEP 01 ] Architecture

Design of business logic and BLoC architecture

We create a clean architecture following the Clean Architecture (Domain, Data, Presentation layers) pattern, API protocols, and data models.

[ STEP 02 ] Design

Creation of Pixel-Perfect UI and animations in Figma

We are drawing our own brand widget library: buttons, swipe cards, dynamic graphs, custom transitions between screens.

[ STEP 03 ] Development

Development on Flutter (Dart 3) in two-week sprints

We implement the client part, fast caching (Hive / Isar / SQLite), interaction with the backend through Dio / Retrofit.

[ STEP 04 ] Integrations

Integration of payment systems and native services

Connecting Apple Pay, Google Pay, biometric login (FaceID / Fingerprint), geolocation and Push notifications (Firebase FCM).

[ STEP 05 ] QA Testing

Automated testing and FPS verification

We write unit tests and widget tests (Widget Testing). We profile rendering through Flutter DevTools to eliminate jank effects.

[ STEP 06 ] Publication

Release in App Store and Google Play Console

We compose the final release bundles IPA and AAB, undergo strict moderation on both sides, and provide 90 days warranty.

[ FREQUENT QUESTIONS ]

Answers to common questions from customers

Key details regarding terms, independent website editing, and rights transfer.

Impeller is a modern graphical engine for Flutter, developed by Google engineers specifically to replace the old Skia engine. It pre-compiles all shaders during app build, completely eliminating shader compilation jank on Apple and Android devices.

On the contrary, updating a Flutter app is significantly easier than two native ones, since all business logic and interface are in one place. In addition, we can connect the Shorebird technology, which allows applying urgent fixes on users' smartphones instantly without re-awaiting moderation.

Yes. Flutter has a mature ecosystem of official and verified plugins for working with Google Maps, Apple MapKit, camera, Bluetooth LE, fingerprint scanners and Face ID.

Yes. The Flutter architecture allows reusing up to 90% code for running a web application (Flutter Web) or a desktop program for Windows and macOS without rewriting the entire logic.

100% ownership rights to all written code, Figma design mockups and signing keys are transferred to your company under an act of completed work.
