Jank on complex animations
Complex paint operations cause frame drops below 60fps. We profile with Flutter DevTools, identify rasteriser bottlenecks, move expensive paints to RepaintBoundary and use cached network images.

Flutter Development Services for One Codebase, Native Performance
Flutter gives US and EU product teams pixel-perfect apps on iOS and Android from a single Dart codebase — without sacrificing performance or native integrations. Personal Account's telecom self-service app, Media Arena's sports news platform and BasilDoc's health and nutrition app are all Flutter-powered, store-approved and live.
We deliver Flutter engineering for consumer apps requiring custom, animation-rich UIs that look identical on iOS and Android; health and lifestyle apps where platform consistency matters for medical and dietary content; telecom and utility apps needing in-app billing, tariff management and account portals; and product teams choosing Flutter over React Native for its superior animation performance and rendering consistency. Every engagement includes App Store and Play Store submission, fastlane signing pipelines and post-launch crash monitoring.
Challenges
Industry challenges we solve
State management at scale
setState and Provider patterns collapse under complex feature state. We migrate to Riverpod with riverpod_generator, establish clear provider hierarchy and scope providers to feature modules.
Platform channel breakage on OS updates
iOS and Android OS updates break MethodChannel implementations silently. We prefer maintained pub.dev plugins and pin plugin versions with compatibility test coverage.
Play Store policy for health and finance apps
Health and finance categories face elevated Play Policy scrutiny. We prepare data safety declarations, minimise sensitive permissions and advise on policy-compliant architecture early.
App size on complex apps
Flutter apps with many plugins and assets grow large enough to trigger Play Store install abandonment. We analyse with flutter build apk --analyze-size, remove unused plugins and implement deferred component loading.
OTA update strategy
Flutter lacks first-party OTA. We implement Shorebird code push for Dart-layer hotfixes and plan native rebuild cycles around OS compatibility requirements.

Why YuSMP
Why Flutter teams choose YuSMP
Riverpod architecture expertise
Senior engineers who have designed Riverpod provider hierarchies for complex feature state, migration patterns from BLoC and performance profiling with DevTools.
Health and finance store experience
We have shipped Flutter apps in health and finance categories — where Play Policy scrutiny is highest and data safety declarations must be precise.
Shorebird OTA for fast hotfixes
Flutter's native compilation makes OTA non-trivial. We wire Shorebird code push for Dart-layer hotfixes so critical bugs reach users without a full release cycle.
FAQ
Flutter FAQ
BLoC or Riverpod — which state management do you use?
Riverpod for new projects — compile-safe providers, testable without BuildContext, excellent code generation with riverpod_generator. BLoC for teams with existing BLoC investment or those who prefer explicit event/state separation for complex workflows. We avoid Provider and SetState for anything beyond local widget state.
Flutter or React Native — how do you choose?
Flutter for pixel-perfect custom UI, smooth 60/120fps animations and consistent cross-platform rendering where the native look is less important than visual fidelity. React Native for teams with a strong TypeScript investment who want to share business logic with a web app. Flutter's Dart performance profile is generally better for animation-heavy apps.
How do you implement platform-specific features in Flutter?
Platform channels (MethodChannel, EventChannel) for calling native Swift/Kotlin code — used for Bluetooth, NFC, biometrics and OS-level integrations not covered by plugins. We prefer a well-maintained pub.dev plugin to custom channels when one exists.
How do you handle App Store and Play Store submissions for Flutter?
Same process as native — Flutter compiles to native ARM binaries, so App Review treats it as a native app. We manage fastlane for signing, screenshot automation and release notes, and EAS-equivalent CI pipelines with Shorebird for OTA updates.
How do you test Flutter applications?
Widget tests for UI component behaviour, integration tests with flutter_test and patrol for end-to-end flows on device/emulator, unit tests for business logic. We gate widget test coverage in CI and run integration tests on real devices in Firebase Test Lab before each release.
Can Flutter apps run on desktop and web too?
Flutter targets iOS, Android, web, macOS, Windows and Linux from one codebase. We typically recommend targeting mobile first and expanding to desktop when there is validated demand — shared business logic, platform-specific UI adaptations.
