Hire Flutter developers
These senior Flutter developers build cross-platform mobile apps in Dart. Each one is assessed on widget architecture, platform-specific behaviour across iOS and Android, release discipline, and how well they verify and direct AI-generated code without losing control of the codebase.
01
AI writes Dart faster than engineers once did
Copilot and similar tools can scaffold widgets, generate state management boilerplate and stub platform channel code in seconds. The risk is that engineers accept that output without checking platform edge cases, so the assessment tests whether a developer can spot what the model got wrong before it ships.
02
Cross-platform gaps are harder to catch now
AI-generated Flutter code tends to paper over iOS and Android differences because it's trained on the happy path. Engineers who rely on it without platform awareness ship subtle bugs in font rendering, keyboard insets and background execution that only appear in production.
03
Release pipelines are more automated and more brittle
CI tooling for Flutter has matured quickly, and AI can generate Fastlane configs and GitHub Actions workflows on request. That speed means engineers can introduce signing, entitlement or flavour mistakes at scale, so we assess whether a developer owns the release process or just runs it.
How we assess Flutter developers
Every engineer works through a fundamentals assessment with AI tools switched off and a second assessment with their own agents running. For Flutter developers, these criteria carry the most weight.
- Debugging
In the fundamentals assessment, the engineer works through a real Flutter codebase with a broken widget tree or platform channel failure and must isolate the cause without AI assistance.
- AI output verification
In the AI-native assessment, the engineer uses their own agents to generate Flutter code, then has to catch platform-specific errors and Dart anti-patterns the model introduced before the code is accepted.
- Spec-driven development
The engineer has to turn a product requirement, such as a specific scroll behaviour or a background sync constraint, into a precise prompt. They then check the output against the original spec, so plausible-looking code that misses the requirement doesn't get through.

Pros and cons of React Native for mobile development
React Native lets you ship one codebase to iOS and Android, with trade-offs. This entry covers performance, cross-platform support, debugging and native API access.
What is a mobile app?
A mobile app is software installed directly on a smartphone or tablet, distinct from browser-based web apps. This entry covers how they're built, distributed and categorised.
How to review AI-generated code
Reviewing AI-generated code changes some of what reviewers look for and keeps the rest. This entry covers both, plus the specific failure modes to check for.
Questions about hiring Flutter developers
How senior are the Flutter developers you place?
The Flutter developers we put forward have 6+ years of experience on average, and they've shipped and maintained production apps in Flutter. Every one has passed both assessments, and you see their scorecards before you meet them.
How do you test Flutter specifically?
The fundamentals assessment uses a real Flutter codebase with broken layouts, platform edge cases and Dart type issues. In the AI-native assessment, the engineer uses their own agents on a Flutter task and has to verify what the model produces before accepting it.
How quickly can a Flutter developer start?
We send you a shortlist within five working days. From there, most engineers are making their first commit within three weeks. That includes time for your interviews, any take-home tasks you want to run, and contract sign-off.
What does a Flutter developer cost?
You pay a fixed monthly fee of €5,600 to €8,000 per full-time engineer, with employment, payroll and compliance included and no recruitment fee. The pricing page compares it with the all-in cost of a senior local hire in your country. Engagements are full-time with a three-month minimum, and if a placement doesn't work out, we replace them at our cost.
Do Flutter developers use our tools or their own?
They use both. Your engineer works in your repo, your CI pipeline and your project management tools from day one. In the AI-native assessment they use their own agents, so you can see how they'd work with any toolchain and how much they trust what it produces.
Get a shortlist within five working days
You share the roles and the stack in a short form or a thirty-minute call. Within five working days you get named senior engineers to review, each with both scorecards.
