Seven years of Flutter app development in production. Impeller rendering at 120fps, Riverpod state that rebuilds only what changed, widget architecture that scales past the tutorial. Flutter owns every pixel on screen — that's what makes it powerful and what makes it dangerous in the wrong hands. We know the difference.
Why Entalogics for Flutter
Widget trees twelve levels deep, setState in fifty screens, jank from rebuilding widgets that didn't change, and a state library picked from a 2021 blog post. The framework isn't the problem — the architecture decisions are.
Most Flutter jank is over-rendering widgets and state changes that rebuild entire screens. We profile with DevTools from day one and fix the architecture, not the framework.
Each feature owns its screens, providers, models, and tests. Shared widgets in a design system package. Two engineers build two features without merge conflicts.
Riverpod 3 gives compile-time safety and async state without manual booleans. Bloc for enterprise teams needing explicit event-state audit trails. We pick for your team size and domain — not by default.
Sealed classes for state machines. Freezed for immutable models. Typed API contracts validated at the data layer. Backend field changes fail the build — not the app.
When Flutter, when not
Flutter gives you one Dart codebase for mobile, web, and desktop. It also renders on its own canvas — platform conventions don't come for free. We'll tell you on the first call if that trade-off works.

What we build with Flutter
The shapes of Flutter development services we deliver most. Each built for production — not a counter app demo.
Onboarding, animations, in-app purchases, push. Pixel-perfect brand experiences where every micro-interaction is intentional.
Your dashboard in your user's pocket. Offline-first with Drift, biometric auth, push tied to backend events.
Product browse, cart, checkout, order tracking. Custom product cards and transitions that feel native on both platforms.
Custom charts, real-time data, interactive dashboards. Flutter's canvas gives you charting without a third-party library's limits.
Replace the spreadsheet your team shares on Slack. Offline capture, photo evidence, sync when connectivity returns.
Provider to Riverpod, Skia to Impeller, Navigator 1.0 to GoRouter. Screen by screen — the app stays live throughout.
The playbook
Dart development patterns from real production — not pub.dev trending.
P01
AsyncNotifier for async operations. Code generation to cut boilerplate. ref.watch in widgets, ref.read in callbacks. No provider leaks across features.
P02
lib/features/auth, lib/features/feed, lib/shared. Each feature encapsulated. Build times stay fast as the codebase grows.
P03
Immutable, equatable, JSON-serializable. Union types for domain state. Generated code that doesn't drift from the definition.
P04
Type-safe routes, deep link support, redirect guards. A screen rename fails the build — not the runtime.
P05
Golden image tests for visual regression. Integration tests on critical flows. CI on every PR. Catches what widget tests miss.
P06
GPU-accelerated rendering on iOS and Android. No shader compilation jank. The frame drops that plagued early Flutter apps are gone.
Signature case
A B2C lifestyle app on Flutter 2 with Provider — setState in 40+ screens, a provider tree nobody could trace, 200ms jank on the home feed, zero test coverage. Rebuilt on Flutter 3 with Riverpod, Freezed, and GoRouter in 10 weeks. Jank eliminated. Coverage went from 0 to 84%.
Before
Flutter 2 Provider · setState in 40 screens · 200ms feed jank · 0% test coverage
After
Flutter 3 Riverpod · AsyncNotifier everywhere · 0ms jank · 84% coverage
Engagement shape
A typical Flutter app development engagement. We build screen by screen — never a six-month rewrite. The current app stays live while we work.
Two senior Flutter developers on the project. Widget rebuild profiling, state management audit, dependency review. A ranked, dollarized RFC.
Flutter 3 baseline, Riverpod wired in, GoRouter, one production screen end-to-end. Real frame times on a physical device.
Feature by feature under feature flags. TestFlight and internal track releases weekly. Your roadmap keeps moving.
Store assets, compliance, first submission. Runbook handed to your team — or we stay on retainer.
Stack
Our default Flutter development stack — picked for production, not pub.dev trending.
Engagement
No hourly retainer that bills for "thinking time." Pick a lane that matches your stage; everything is fixed-quote or transparently rated.
A defined product, a fixed price, a senior-only team. From RFC to app store submission in 8–14 weeks.
$15k–$30k
FIXED SCOPE
Embedded engineers in your Slack, your Linear, your standups. Senior Dart engineers shipping cross-platform apps. Pause, resize, end with 30 days' notice.
$5k / eng / mo
PER ENGINEER
A long-term partner for product orgs shipping cross-platform — architecture, performance, design system, hiring help.
