[Get a project quote →](/contact/) [See how it works](#engagement) 100k+ Flutter apps using GetWidget 1000+ Flutter projects shipped 48h Dev match average $18–60/hr Junior to Lead, India [Backed by **GetWidget** ↗](https://www.getwidget.dev/) Which do you need? ## Full-service delivery vs. developer staffing: know the difference. 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. Full-service (this page) Developer staffing Discovery + technical spec Included: 1-2 week sprint Bring your own UI/UX design Included: Figma-to-Flutter Not included Flutter implementation Full team included Core service Backend + API integration Included: Firebase / Node / Supabase Bring your own backend team QA + device testing Included: iOS, Android, tablet Bring your own QA App Store submission Included: both stores Not included Launch support Included: 2-week post-launch window Not included Post-launch maintenance Optional retainer available Extend contract separately Project management Included: dedicated PM Bring your own PM Need a single developer to embed in your existing team? See the dedicated Flutter developers page. Need a vetted senior Flutter engineer for your team rather than full project delivery? [See /dedicated-flutter-developers/ →](/dedicated-flutter-developers/) What's included ## What's included in a Flutter app development engagement? One engagement covers every phase from blank screen to live app. No hidden add-ons, no "that's extra" surprises after contract sign. 🔍 ### Discovery + technical spec (weeks 1-2) 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. 🎨 ### UI/UX design: Figma to Flutter 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. 📱 ### Flutter implementation, AI-accelerated 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. 🚀 ### QA, App Store launch + post-launch support 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. Get a quote ## Want a project quote for your Flutter app? Tell us your scope and we'll return a written fixed-price quote after a 30-minute discovery call. No obligation. Get a project quote → [Email us](mailto:sales@getwidget.dev) How it works ## What are the 5 phases of a Flutter app development engagement? 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. 1. 01 ### Discovery week Week 1-2 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. 2. 02 ### Design sprint Week 2-3 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. 3. 03 ### Build phase Weeks 4-10 (typical) 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. 4. 04 ### QA + App Store launch Final 2 weeks 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. 5. 05 ### Post-launch support 2 weeks included 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. What you actually get ## What does a Flutter app development services team actually deliver? "We'll deliver the app" is not a deliverable. Below is the artifact list per phase. If a partner won't commit to this level of specificity before contract, that's the sign to walk. ### Phase 1 · Discovery - Written scope document (15-25 pages) with feature list, screen list, integrations, success metrics - Risk register: API dependencies, compliance scope, App Store review risks - Tech stack decision doc: state management, backend, analytics, CI/CD - Fixed-scope quote OR T&M tier breakdown, written ### Phase 2 · Design - Figma file with every screen at 1× spec, including loading and empty states - Design system tokens exported (colors, type scale, spacing) wired into Flutter ThemeData - Clickable prototype on Figma share link for stakeholder sign-off - Accessibility pass: WCAG AA contrast, touch target sizes, semantic labels ### Phase 3 · Build - Flutter app codebase in your GitHub org from day one (not handed over at the end) - Weekly demo build on TestFlight + Firebase App Distribution - Sprint reports with shipped tickets, blockers, next-week plan - Test coverage report: unit + widget + golden tests, 60%+ target ### Phase 4 · Launch - App Store + Google Play submission with screenshots, listing copy, privacy nutrition labels - Production CI/CD pipeline (Codemagic or GitHub Actions) for both stores - Crash reporting wired (Crashlytics or Sentry), with alert rules - Launch-day runbook: rollback plan, hotfix path, support escalation ### Phase 5 · Post-launch - 30-day stability window: bug fixes at no charge if introduced during build - Monthly retainer option for feature work and OS-version upkeep - Full source code + design files + ops docs in your repo and Drive - One-hour knowledge transfer call if you take it in-house ### Across all phases - Slack channel with your dedicated team (not a ticket queue) - One named project lead for the whole engagement, not a rotating account manager - Loom-recorded handovers when timezone makes synchronous calls expensive - Written decisions in a shared Notion or Linear, not buried in DMs Timeline ## How long does a typical Flutter MVP take to ship? Industry median for a Flutter MVP is 12 weeks. Our median is 5-6 weeks for the same scope, driven by GetWidget UI kit + AI-augmented workflow. Concrete week-by-week breakdown of a typical 6-week MVP. Week 0 ### Discovery + scope lock 30-min call, written scope back in 48 hours, contract signed by end of week. Figma starter file with screen list seeded. Week 1 ### Design + Flutter project bootstrap Design lead drafts all screens in Figma. Dev lead spins up the Flutter project, wires GetWidget components, CI/CD, analytics, crash reporting. App opens on day 3. Week 2 ### Core feature build Auth, onboarding, primary user flow. First TestFlight build out by end of week. Stakeholder sign-off on design system + key screens. Week 3 ### Secondary features + backend integration REST/GraphQL integration, push notifications, in-app payments if scoped. Second TestFlight build with full happy path working. Week 4 ### Polish + edge cases Empty states, loading states, error handling, offline behavior. Accessibility pass. Performance profiling. Third TestFlight build for beta testers. Week 5 ### Store submission + launch prep Screenshots, listing copy, privacy labels, age ratings. Submit to both stores. Apple review averages 24-48 hours, Play averages 1-7 days. Launch runbook signed off. Week 6 ### Launch + 30-day stability window App live on both stores. Crashlytics monitored daily. First-week hotfixes shipped within hours, not days. Roadmap conversation for v1.1 starts week 7. Scope-and-team variance: a single-screen utility app ships in 3-4 weeks. A multi-tenant SaaS Flutter app with admin panel, role-based auth, and 40+ screens runs 10-14 weeks. The 5-6 week median assumes ~15 screens, one backend, and a clear v1 cut. Service pricing ## Should you pick fixed-scope or time-and-materials for Flutter? We don't pretend fixed-scope works for every situation. Here's when each model makes sense and what each actually costs. 📋 ### Fixed-scope project: $15k to $80k typical 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. ⏱ ### Time + materials: tiered hourly rates 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. T&M tier rates ## If you go time and materials: four tiers, clear rates. Most service engagements start fixed-scope for the MVP, then move to T&M for ongoing product development. Monthly rolling contracts, 4-week minimum. ### Junior $18/hr ~$2,800/mo 1-2 years Flutter. AI-augmented for routine feature work under Senior oversight. - Spec'd features - Under Senior supervision - CRUD + integrations ### Mid $28/hr ~$4,400/mo 3-5 years. Independent on standard screens, reviews Junior PRs. - State management - REST/GraphQL - App Store releases Recommended ### Senior $40/hr ~$6,200/mo 5-8 years. Architecture, performance, leads T&M engagements end-to-end. - Owns features end-to-end - Client-facing demos - Reviews all PRs [Most T&M clients use this tier →](/contact/) ### Lead $60/hr ~$9,200/mo 8+ years. Runs multi-dev engagements, owns sprint planning and delivery. - Multi-dev team lead - Sprint planning - Architecture sign-off 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 →](/hire-flutter-developers-india/) AI-augmented delivery ## Four pillars of our AI-native Flutter workflow. "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. 🤖 ### Claude Code + Cursor pair programming 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. 📦 ### GetWidget UI kit: 20-30% less UI work 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. 🧪 ### AI test generation: higher coverage, faster 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. 🔍 ### AI code review on every PR 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. Want the full technical breakdown? [See our AI workflow page →](/ai-augmented-flutter-development/) Industries we serve ## Full-service Flutter delivery across every vertical. 1000+ production Flutter projects shipped.

We answer this question on the first discovery call, every time. After 1,000+ Flutter projects shipped, the same five criteria predict whether the engagement ends in a launched app or a half-built codebase. Use this checklist on us. Use it on anyone else you talk to. 1. **Ask to see their commit log on a past project.** A live GitHub history beats a polished case-study PDF. We send a redacted six-month commit log on request — PR titles, review threads, merge cadence. If a Flutter shop refuses, that's the answer. 2. **Verify the senior-to-junior ratio on your engagement.** Pitch decks say "senior team." Reality is often 1:5 with a Lead spread across four clients. We staff at 1 Lead : 2 Senior : 1 Mid : 1 Junior on a typical Flutter pod, and the Lead reviews every PR. Ask for the actual ratio on your project before signing. 3. **Get the AI workflow specifics.** "We use AI" means nothing. Ask which tools (Claude Code, Cursor, Copilot), how they integrate (pre-commit, PR review, prompt library), and what we measure (PR-to-merge time, test coverage, ticket-to-ship). The full breakdown is on our [AI workflow page](/ai-augmented-flutter-development/). 4. **Test the discovery process before signing.** Our first deliverable is a two-week discovery with wireframes, API contracts, and a fixed-scope build brief. If a partner can't do discovery before quoting, they're guessing. You pay for the guess in change orders. 5. **Read the replacement guarantee, not the marketing.** We replace at no cost inside 30 days if a developer isn't the right fit. Most agencies promise "best fit" but quietly bill you while they swap people. Get the guarantee in writing before the SOW. Security & compliance ## Data integration, app security, and compliance baked into delivery. Every Flutter app we ship runs through the same security baseline. Our leads have shipped under HIPAA (US healthcare), GDPR (EU), and PCI-DSS scope (payments). These defaults are included in every engagement, not a paid add-on we upsell. - **Secrets handling.** No API keys in source. We use Firebase Remote Config, AWS Secrets Manager, or platform Keychain/Keystore depending on your stack. A pre-commit hook (truffleHog) scans every commit. - **Auth flows.** Google Sign-In, Apple Sign-In, and email magic links via Firebase Auth or Supabase Auth. JWT validation on every protected route. Biometric auth (Face ID, fingerprint) where it adds value, not as a marketing checkbox. - **Data at rest, data in transit.** TLS 1.3 everywhere. Local DB encryption via sqflite\_sqlcipher or Hive's encrypted boxes. iOS Data Protection class set to NSFileProtectionComplete on sensitive payloads. PII scrubbed at the logging layer before it reaches Sentry. - **Compliance posture.** GDPR consent flow, data export, and deletion APIs ship by default. HIPAA-eligible Firebase plus signed BAA on healthcare engagements. PCI-DSS scope reduction via Stripe Elements or Razorpay tokenization, so raw card data never touches your Flutter app. - **Observability.** Sentry for crash and error reporting, Firebase Crashlytics for native crashes, Datadog or New Relic for backend traces if you bring one. We instrument the Flutter layer the day we ship a feature, not a quarter after launch. Launch process ## Shipping Flutter apps to the App Store and Google Play. First-time iOS or Android submissions get rejected 30% of the time. We've shipped 1,000+ Flutter apps to both stores and we know the unwritten rules. Our launch checklist turns first submission into first-pass approval most of the time. - **iOS App Store prep.** TestFlight build first, never direct production. The App Privacy questionnaire is reviewed against your actual data flows, not a boilerplate yes-all. Screenshots generated per device class via Fastlane snapshot. Apple ID is configured with an App-Specific Password before submission. - **Google Play prep.** Internal testing track first, then closed alpha, then production. Data safety form completed with the real SDK list, not "general" tags. App bundle (.aab) signed via Play App Signing. We review the pre-launch report before promoting any build. - **CI/CD baseline.** Codemagic or Fastlane for both stores. A tagged Git release ties to a specific App Store and Play Store build number, so rollback is auditable. Build numbers auto-increment. Changelog generated from PR titles via conventional commits. - **First 30 days post-launch.** We watch Sentry, Crashlytics, and App Store / Google Play review responses daily. We respond to user reviews on your behalf if you don't have a community manager yet. Hotfix track kicks in for any crash above 0.5% session-crash rate. - **Track record.** Zero of our shipped apps has been removed from either store. App Store first-pass approval rate: 89% over the last 12 months (2026-Q1). Median time from final code-freeze to live in store: 7 days. Free scoping ## Free 30-minute project scoping call.

Same engineering team that ships HireFlutterDev engagements. " > We had earlier worked on 4–5 projects with the GetWidget team. Choosing Supabase as our backend was tough — we wanted to ship fast — but their understanding of it helped us go further than our earlier plan. Now I'm looking to build a full-scale app with them. **Johnathan Dane** CEO · KlientBoost ★ 5.0 · DesignRush " > Get Widget has been nothing short of transformative for our POS application. Their developer showed a thorough comprehension of our specifications and gave frequent updates. Built on Flutter, GraphQL and Postgres — the software is very smooth compared to the old version. **Ugo Philippe** Co-Founder & Associate Director · Agence THRIVE ★ 5.0 · DesignRush " > Existing CRMs were too expensive and missing customization, so we built our own. The hard part was integrating many third-party APIs — they took the calls themselves and saved me the headache of relaying technical details. They work like it's their own project — that is the thing I like most. **Kyle Kotack** CEO · Skylar Media Group ★ 5.0 · DesignRush " > We explored and contacted many companies and based on budget and technology we were looking to use, decided to partner with GetWidget to develop a hybrid mobile app for my B2C e-commerce business. The tech stack they suggested was very good — we wanted to go native but they recommended Flutter for hybrid, and we are very happy with the experience the app gives to us. **Sukesh Jakharia** CEO · SPINX Digital ★ 5.0 · DesignRush " > For our company, working with GetWidget to develop mobile apps was revolutionary. GetWidget immediately won us over with their creative ideas and aggressive approach. The ability of GetWidget to materialize our idea was what impressed us the most. **Tripp Donnelly** Founder and CEO · REQ, An Agital Company ★ 5.0 · DesignRush " > To create a powerful mobile application that would improve consumer engagement and expedite our business processes, we turned to their experience. GetWidget showed professionalism, inventiveness, and technical mastery right away. **Jeffrey Wharton** Director · SYSTRA USA ★ 5.0 · DesignRush FAQ ## Questions we get before the discovery call. Fixed-scope vs. T&M: how do I choose? + Fixed scope works when you have a clear, written feature list and aren't planning major pivots mid-build. T&M works when you're building a product that will evolve, have a roadmap that isn't finalized, or want ongoing development after the MVP. Most first engagements are fixed-scope (lower risk to both sides); ongoing product development moves to T&M. Who owns the IP and code? + You do, fully, from day 1. All code is committed to your repository under your organization. We sign an IP assignment agreement as part of the contract. We retain no rights to your codebase, designs, or business logic after the engagement ends. What happens if scope changes mid-project? + On fixed-scope projects, scope changes are handled via a written change request: we scope the addition, quote it, you approve before we build. Nothing is added to the project without written agreement. On T&M projects, scope changes are natural. You add items to the backlog and we prioritize in sprint planning. Is a project manager included? + Yes. Every full-service engagement includes a dedicated PM from our side. They run daily standups, maintain the sprint board, own client communication, and keep the delivery timeline accountable. You don't need a technical PM on your side to work with us, though you're welcome to assign one. Is design done in-house or subcontracted? + Design is done in-house by our own UI/UX designers who specialize in mobile-native Flutter products. We do not subcontract design to third parties. Designs are produced in Figma and handed off as Flutter-component-spec'd files, not generic app mockups. Do you handle App Store and Google Play submission? + Yes. We submit to both App Store Connect and Google Play Console from your developer accounts. We prepare all required metadata (screenshots, descriptions, privacy policy URL, age ratings), respond to review rejections, and track the review queue through to approval. Apple review times average 1-3 days; Google typically 24-48 hours. What's included after launch? Do you maintain the app? + A 2-week post-launch critical-bug fix window is included in every service engagement at no additional cost. For ongoing maintenance (Flutter version upgrades, SDK updates, new features, OS compatibility patches) we offer a monthly retainer. Most clients start with a 10-20 hour/month retainer for light maintenance. How is QA done? What devices do you test on? + QA is a full phase in our process, not an afterthought. We test on real devices: iPhone SE, iPhone 15, iPad (latest), Pixel 7, Samsung Galaxy mid-range, and one low-spec Android device. Test types: functional, regression, performance profiling (Flutter DevTools), deep-link navigation, and background/foreground state handling. All major flows are covered before submission. How much does a typical Flutter app cost with your service? + A 6-10 screen MVP (login/auth, 3-4 core features, Stripe payment, push notifications, basic admin panel) typically runs $15k-$25k fixed-scope with our AI-augmented delivery. Mid-complexity apps with custom backends, multi-role workflows, and real-time features run $25k-$50k. Enterprise-scale or heavily regulated apps (fintech, healthcare) run $50k-$80k. We provide a written quote after the discovery sprint. How long does it take to build a Flutter app? + A 6-10 screen MVP typically ships in 8-12 weeks from signed contract to App Store approval. Mid-complexity apps run 12-16 weeks. Our AI-augmented delivery is 40-60% faster than standard agencies on equivalent scopes. The discovery and design phases (weeks 1-3) front-load the decisions that most agencies leave to mid-build, which reduces rework significantly. Questions about developer staffing instead?
