Services

Hire a dedicated Flutter developer to bring your mobile app project to the next level. Our consultants work as part of your existing development team and process, or as a stand-alone resource, ensuring the highest standards of communication throughout the project.

Every engineer we place is US-based and senior. We work on the current Flutter stack — Flutter 3.44 and Dart 3.12 as of mid-2026 — and we are honest about what that stack is good at and where it is still catching up.

Build

Greenfield Flutter applications for iOS, Android, web, and desktop (macOS, Windows, and Linux) from one codebase.

• Product and UX strategy, then design systems built on Material 3 and Cupertino
• Custom UI, animation, and 120 Hz performance work on the Impeller rendering engine — now Flutter's default renderer on iOS and Android
• State management done deliberately: Riverpod or Bloc, chosen for your team rather than by habit
• Internationalization with the intl package and Flutter's localization tooling
• Web builds, including WebAssembly (WasmGC) compilation where it pays off

Modernize

The largest body of Flutter work in 2026 is not new apps — it is apps built on Flutter 1.x and 2.x that have stopped upgrading cleanly.

• Flutter 2.x / 3.x to 3.44+ upgrades, run incrementally and behind a test safety net
• Dart 3 migration: sound null safety, records, patterns, and sealed classes
• Skia-to-Impeller rendering audits, including custom shaders and CustomPainter code
• Readiness for the post-3.44 direction of decoupling Material and Cupertino from the core framework
• Triage and replacement of abandoned pub.dev dependencies

See our Flutter app modernization page for how a typical upgrade engagement runs.

Integrate

• Platform channels when you need them — and dart:ffi, ffigen, and jnigen when direct native interop is the better tool
• Add-to-app: Flutter modules embedded in existing iOS and Android codebases
• Third-party SDK integrations (payments, analytics, maps, auth) via native SDKs or maintained plugins
• React Native to Flutter migration assessments, including honest advice when staying put is the right call

AI in the app

Shipping AI features that survive contact with production, not demos.

• Streaming chat and agent UIs with cancellation, retry, and latency handling
• Firebase AI Logic (Gemini) and Claude API integration patterns, always behind your own backend
• On-device inference for offline and privacy-sensitive use cases
• Token cost controls, safety UX, and store-review readiness

AI-accelerated engineering

Our consultants pair Flutter's production AI tooling and agentic coding workflows with senior code-review gates, so you get 2026 velocity with senior-grade quality.

• Agentic coding workflows with human review on every change
• Test-suite generation and hardening for legacy codebases
• Automated CI/CD for Flutter — GitHub Actions, Codemagic, Bitrise, or Xcode Cloud, with Fastlane for store delivery
• Store compliance, release trains, and staged rollouts

Quality

• Unit, widget, and integration tests, plus golden tests for pixel-level UI regression coverage
• Debugging and profiling with Dart DevTools, the Dart analyzer, and Flutter Inspector
• Crash and performance monitoring with Sentry or Firebase Crashlytics
• Accessibility reviews: semantics, contrast, dynamic type, and screen-reader testing on both platforms
