End-to-end Flutter app development from discovery to App Store launch. We handle design, implementation, backend integration, QA, and submission, so you ship a product, not just a codebase. AI-accelerated delivery. 40-60% faster than traditional agencies.
This page is for buyers who want an agency to own the whole project, design through launch. If you already have a PM, design, and backend, and just need Flutter engineers embedded in your team, that's a different engagement.

One engagement covers every phase from blank screen to live app. No hidden add-ons, no "that's extra" surprises after contract sign.
We map your user journeys, audit your existing tech stack (if any), define API contracts, choose state management patterns, and produce a written spec you sign off before a line of code is written. No surprises, no scope creep from ambiguity.
Our designers produce mobile-native Figma screens matched to your brand, with a component library that translates directly into GetWidget-based Flutter widgets. Design review happens before implementation, not after.
Senior Flutter engineers build with Claude Code, Cursor, and our internal Flutter prompt library. Every PR has AI review + human review before merge. GetWidget UI kit cuts UI work by 20-30%. Daily standups, weekly demos.
Device matrix QA across iOS and Android (phone and tablet). We handle App Store Connect and Google Play Console submission, respond to review rejections, and provide a 2-week post-launch support window for critical bugs.
We front-load the decisions. Most agency cost overruns trace back to ambiguous specs and design-during-development. Our process forces clarity before the build clock starts.
30-minute scoping call followed by a structured discovery sprint. We document user journeys, define the feature set, agree on the tech stack, and deliver a written spec with timeline and fixed-price quote before you commit to the build.
Figma designs for all screens, component library finalized, client sign-off required before build starts. We do one revision round on the initial designs. Mobile-native patterns only. No desktop-ported layouts.
AI-augmented Flutter engineers build in two-week sprints. Weekly demo calls with working software, not status slides. Code lives in your repository from day 1. Daily standups, async updates on Slack or your preferred channel.
Full device matrix QA across iOS/Android, regression testing, performance profiling. We handle App Store Connect and Google Play Console submission from your developer account, respond to review rejections, and stand by for launch.
Critical-bug fixes at no additional cost for 2 weeks post-launch. Optional monthly maintenance retainer for ongoing updates, SDK upgrades, and Flutter version migrations. Hand off to your in-house team with full documentation.
We don't pretend fixed-scope works for every situation. Here's when each model makes sense and what each actually costs.
Best for well-defined MVPs and greenfield builds. We scope with you in discovery week, produce a written spec, you approve the quote, we deliver. No monthly billing surprises. Most 6-10 screen MVPs land between $15k and $30k. Complex multi-role apps with custom backends run $40k-$80k. Scope changes are priced and approved before implementation.
Best for evolving products where the roadmap grows over time. Monthly billing against actual hours at your assigned tier rate. Full transparency: time logs, weekly summaries, no scope-creep negotiations. Typical T&M engagements run 3-6 months. Rates: Junior $18/hr · Mid $28/hr · Senior $40/hr · Lead $60/hr.
Most service engagements start fixed-scope for the MVP, then move to T&M for ongoing product development. Monthly rolling contracts, 4-week minimum.
1-2 years Flutter. AI-augmented for routine feature work under Senior oversight.
3-5 years. Independent on standard screens, reviews Junior PRs.
5-8 years. Architecture, performance, leads T&M engagements end-to-end.
8+ years. Runs multi-dev engagements, owns sprint planning and delivery.
All T&M rates are full-time dedicated (160 hrs/month). Part-time available at +20%. 10% off at 3-month commit, 15% off at 6-month. See full rate breakdown →
"AI-accelerated" is our most-questioned claim. Here's exactly how it works and why it produces higher-quality code, not lower. Backed by 1000+ shipped Flutter projects.
Every engineer runs Claude Code and Cursor full-time. Routine widget scaffolding, state management boilerplate, and integration code that used to take hours takes minutes. Engineers spend their time on architecture, not repetitive markup.
Our own open-source Flutter component library (used in 100,000+ Flutter apps) is baked into every project. Buttons, cards, lists, modals, form fields: pre-built, pre-tested, on-brand in one config update.
Test scaffolds are cheap when AI writes the boilerplate. We typically ship with 70-80% unit/widget test coverage, which would take 2-3× longer without AI assistance. QA finds fewer bugs because tests catch them first.
Every pull request runs an AI review pass (catching null safety issues, state anti-patterns, and performance problems) before a human reviews it. Our human senior engineers see cleaner diffs and focus on architecture, not lint.

Hourly rate alone misleads. Scope clarity, AI velocity, and quality-to-rework ratio all shift the final number. Here's the realistic cost of a 6-10 screen MVP across agency types.
| Hourly rate | Typical MVP cost 6-10 screens, auth, payment, push notifications | Timeline to App Store | |
|---|---|---|---|
| US full-service agency | $120-180/hr | $80k-$200k | 18-26 weeks |
| Premium India agency | $35-55/hr | $20k-$40k | 14-20 weeks |
| hireflutterdev (AI-augmented) | $18-40/hr | $15k-$25k | 8-14 weeks |
| Bargain offshore | $8-12/hr | $8k-$15k | Lottery on timeline |
Cost estimates based on 1000+ shipped Flutter projects. Fixed-scope quotes depend on your specific scope.
We came in expecting a developer for hire. What we got was a team that owned the whole thing — spec, design, build, App Store. Our previous agency billed us for QA and submission separately. Here it was just... included. We shipped in 11 weeks. The design is better than what we had from our old Figma freelancer.
