What does a Flutter developer do?
A Flutter developer builds cross-platform mobile (and increasingly web/desktop) applications using Flutter and Dart. Strong Flutter engineers understand the widget tree and rendering pipeline, manage state cleanly with Riverpod or BLoC, integrate with native platform channels when needed, and ship performant apps to both iOS App Store and Google Play.
Why Flutter is a strong choice for modern engineering teams
- •One codebase for iOS and Android (and web/desktop) dramatically cuts mobile build time.
- •Backed by Google with a strong release cadence and LTS story.
- •Excellent UI performance — consistent 60/120fps with custom design systems.
- •Large plugin ecosystem covers most native integrations out of the box.
- •Strong choice for startups that need mobile presence on both platforms quickly.
Skills to look for when you hire Flutter developers
Dart fluency
Null safety, async/await, streams, isolates, and modern Dart idioms.
Flutter widget system
Stateful vs stateless widgets, build contexts, keys, and the rendering pipeline.
State management
Riverpod, BLoC, or Provider; knows when each fits and how to test it.
Navigation & routing
go_router or Navigator 2.0; deep linking and auth-aware flows.
Platform integration
Platform channels for iOS/Android native features; plugin authoring when needed.
App store delivery
Signing, build flavours, Fastlane, App Store Connect and Play Console.
Testing
Widget tests, integration tests, and golden tests for visual regressions.
Performance
DevTools profiling, rebuild minimisation, image and list virtualisation.

Frequently asked questions
Is SquadXP GDPR-compliant for UK engagements?▾
Yes. Every engagement runs on GDPR-aligned contracts and processes, with UK Data Protection Act specifics handled in the MSA. NDAs are signed before any candidate sees your brief.
How fast can I hire a Flutter developer through SquadXP?▾
You'll get the first pre-vetted candidate CV within 24 hours of the intake call. Most clients finalise a Flutter hire within 48 hours and onboard within the same week.
What if the first hire doesn't work out?▾
You have a 7-day replacement window, no questions asked. We'll start sending replacements the moment you flag it — no invoices, no friction.
Can I hire Flutter developers across US, UK and EU timezones?▾
Yes. Our network spans multiple regions, so we can match any timezone overlap requirement — from full US hours to split UK/EU coverage.
Is this contract, full-time, or project-based?▾
All three. We support short-term projects, long-term contracts, and contract-to-hire. Most clients start with a 3-month engagement and extend.
Do you handle payroll, compliance, and NDAs?▾
Yes. SquadXP handles contracts, NDAs, payroll, tax compliance, and invoicing. You get a single monthly invoice and don't have to manage any local entity.

Standard NDAs are in place before any candidate sees your brief. We follow NDA, HIPAA-aligned, and ISO 27001 processes. All engineers work on dedicated, encrypted machines.

Yes. If you need a team (Flutter engineers + supporting roles like DevOps or QA), we source as a unit, including a team lead, and onboard them together.
Do your Flutter developers also handle native iOS/Android when needed?▾
Many do. Tell us you need native depth (Swift or Kotlin plugin work) and we'll match engineers with both skills.

Yes. Several of our Flutter developers pair with Node.js or Python backends for a single-person full-stack profile.
