WHY FLUTTER

One UI, every platform

Flutter renders every pixel with its own engine. The same UI runs on iOS, Android, web and desktop on top of Dart compiled to native.

Pixel-perfect UI

Same widget tree, same render, same brand on iOS and Android. The design ships exactly as the product team signs it off.

Impeller at 120fps

AOT compilation to ARM64 and the Impeller graphics engine. Sustained 120fps animations, scrolling and transitions on high-end devices.

Sub-second Hot Reload

Changes reflect on the device in under a second while keeping state. The iteration loop becomes part of the design flow.

iOS, Android, web and desktop

A single Dart codebase for mobile, web and desktop. Same rules, same domain, same components across every target.

REAL-TIME COMMUNICATIONS

VoIP, SIP and WebRTC on Flutter

We build real-time voice and video from a single Flutter codebase. flutter_webrtc, sip_ua and livekit_client integrated with CallKit and ConnectionService through native channels.

01 / 04

Cross-platform VoIP and SIP

SIP clients built on dart-sip-ua and sip_ua, with a PJSIP bridge when the carrier requires it. Registration, INVITE, REFER and NOTIFY handled from Dart, keeping a single signalling logic for iOS and Android.

WebRTC from a single codebase

Real-time voice and video with flutter_webrtc. SDP negotiation, ICE and renegotiation centralized in Dart. Same pipeline for mobile, web and desktop on top of the same state machine.

CallKit and ConnectionService via channels

CallKit on iOS and ConnectionService on Android wired in through platform channels. Background incoming calls, audio routing, lock-screen UI and camera/mic permissions resolved per platform.

Codecs, SFU and real network

Opus for voice, H.264 and VP9 for video. Connection to our own or managed SFU (LiveKit, Jitsi), TURN/STUN and jitter, RTT and packet-loss metrics exposed from the app.

Same experience, two stores. Calls in production with real-world metrics.

FLUTTER ARCHITECTURE

State, data and quality in the same codebase

Riverpod, Dio, Drift and automated testing over Melos. A single architecture for every platform, aligned with the rest of the product.

01
01 / 03

State

  • Riverpod 2 and BLoC over sealed classes
  • freezed for immutable models
  • Declarative routing with go_router
  • Dependency inversion via get_it / Riverpod
02
02 / 03

Data

  • Dio + Retrofit for typed HTTP clients
  • Drift / Isar for local persistence
  • Isolates for heavy work off the UI thread
  • Result/Either for explicit error handling

Quality

  • Golden tests per component and per screen
  • integration_test on real devices
  • Melos for multi-package monorepos
  • fastlane and CI/CD to TestFlight and Play Console
WHEN FLUTTER

When Flutter is the right call

Flutter fits when the UI is a differentiator, the team is one and the product needs to be in several stores and platforms at the same time.

Branded, differential UI

Design is part of the product. Animations, transitions and custom components delivered exactly the same on every platform.

Cross-platform with native parity

iOS and Android shipped from day one. Web and desktop added on the same domain when the product calls for it.

One unified team

One team, one stack, one PR. Business logic lives in Dart and is shared across every target.

Short time-to-market

Sub-second Hot Reload and a single release pipeline. Every sprint closes with signed builds on TestFlight and Play Console.

SUCCESS STORIES

Companies that trust our team

Clients that shipped Flutter apps to production with a single codebase and an identical UI on iOS and Android.

FAQ

What teams ask before choosing Flutter

Concrete technical decisions: real-world performance, bundle size, native integration and RTC support.

  • Does Flutter match native performance in production?
    For most products, yes. Impeller compiles to ARM64 and sustains 120fps on high-end devices. For AAA games, AR/VR or heavy GPU compute, we still pick native and wire it in through channels.
  • How does Flutter compare to React Native?
    Flutter renders its own UI with Impeller and delivers an identical experience on iOS and Android. React Native uses the system's native components. We pick Flutter when the UI is a differentiator; React Native when JS ecosystem and web reuse take priority.
  • What is the bundle size of a Flutter app in the stores?
    A Flutter app starts at 12-18 MB on Android and 18-25 MB on iOS depending on features. We optimize with icon tree-shaking, ABI splits, deferred components and App Bundle to ship only the code each device needs.
  • Does it integrate well with existing native modules?
    Yes. Platform channels expose Kotlin/Swift APIs to Dart, and Pigeon generates a typed binding. We slot Flutter into existing native apps with add-to-app when the migration is progressive.
  • Does Flutter support real VoIP, SIP and WebRTC?
    Yes. We work with flutter_webrtc, sip_ua and livekit_client, and integrate CallKit and ConnectionService through channels. Background incoming calls, audio routing and VoIP push notifications handled from the first release.
