What Netofficials delivers

One Flutter codebase, from scope to store release

Written discovery scope

Before any Flutter code is written, we turn your brief into a written scope: the screens, user roles, backend and third-party integrations, and what the first iOS and Android release includes. You see what is in and out up front, so cost and timing rest on agreed boundaries and not on assumptions.

Cross-platform design and architecture

Our technical architect is accountable for system design, technology selection and code quality standards. You get one interface design and one architecture for iOS and Android, with platform-specific behaviour such as navigation, permissions and notifications planned in from the start, not patched in late.

Build, QA and release with one team

A single cross-functional team covers front-end, back-end, mobile, QA and DevOps, and a named delivery lead keeps you informed. Every sprint ends with a client-facing review, and at release you receive documentation and deployment access, so you can run the app without depending on us.

Who it suits

Flutter suits the app you plan to ship twice

  • A new mobile product launching on iOS and Android together from one Flutter codebase
  • An app on two separate codebases that you want to consolidate into one
  • A product that needs heavy native platform features, where we may recommend Swift or Kotlin after scoping

How a Flutter project runs

How your Flutter app moves from brief to store release

  1. Discover

    We turn your brief into a written discovery scope for the Flutter app: target users, the screens and flows the first release needs, and the device and backend integrations involved. You review it and raise anything we have missed.

    You receive
    • Written discovery scope
    • Open questions list
    • Initial estimate

    You approve the written first-release scope

  2. Design

    Our designers map the user flows and interface for iOS and Android, and our technical architect sets out the app structure, state management and API approach. You review how the app should look and behave on both platforms.

    You receive
    • App user flows
    • iOS and Android designs
    • Architecture notes

    You sign off the designs before development starts

  3. Build

    One cross-functional team builds the app from a single Flutter codebase in Agile sprints, with back-end work and QA alongside. Your named delivery lead keeps you updated as each sprint progresses.

    You receive
    • Staging app builds
    • Sprint review notes
    • QA test results

    You review the working app at the end of every sprint

  4. Test

    QA checks the app on the iOS and Android devices and OS versions agreed in scope, against your acceptance criteria. You test the build yourself, and we log and fix what comes up.

    You receive
    • Acceptance checklist
    • iOS and Android QA report
    • Resolved issue log

    You accept the app on iOS and Android against the agreed criteria

  5. Release

    We prepare the production release of your Flutter app and plan deployment for both platforms. You review the handover pack, including documentation and deployment access, before we close the project.

    You receive
    • App store release
    • Handover documentation
    • Deployment access handover

    You confirm the handover pack before the project closes

Decisions before estimates

What shapes your Flutter app estimate

Screens, roles and native features

Your estimate starts with what the app must do on iOS and Android: the number of screens, user roles and permissions, and any native features such as camera, push notifications, maps or biometric sign-in. We list these in the written discovery scope, so you can see what drives cost and timing before delivery begins.

Backend, APIs and data

Your Flutter app is only as capable as the systems behind it. We map the APIs, databases and third-party services it must connect to, and whether the back end exists or needs building. Our single cross-functional team covers back-end work too, so the estimate does not split across vendors.

Store release and ongoing support

We plan App Store and Google Play submission, QA across devices and operating system versions, and deployment access at handover before you commit. If your product leans heavily on platform-specific features, we will say after scoping whether native Swift or Kotlin would serve you better.

Hire Flutter developers

Three ways to hire a Flutter team

Project delivery

Fixed-price delivery of a Flutter app for iOS and Android, suited to you if the first release can be defined in a written discovery scope.

  • Fixed price set after the written discovery scope and agreed before the build
  • Sprint reviews where you see the working Flutter app on iOS and Android
  • Native Swift or Kotlin recommended after scoping if it suits your app better

Dedicated team

A dedicated India-based Flutter team that builds your app and its later releases, suited to products with a roadmap that keeps growing.

  • Flutter developers matched to your app, plugins and release process
  • Flutter developers and a named delivery lead who run sprints with your product owner
  • Source code and IP assignment confirmed in the contract before the build begins

Staff augmentation

Flutter app developers who join your in-house team, suited to you if you already run the product and need more mobile capacity.

  • Flutter engineers added to your team for a specific gap, such as app architecture or QA
  • Engineers who work in your repositories, ticketing and release process
  • Meeting schedule and update cadence agreed with you before the first commit
Technology we build with

Flutter and Dart, matched to your app

Flutter is Google's UI toolkit, and Dart is the language it is written in. We build your iOS and Android app from one Flutter and Dart codebase, so you maintain a single product instead of two. The technical architect confirms the rest of the stack in the written discovery scope: backend, APIs, state management and any native features your app needs. That choice follows your requirements and your existing systems, so you see the technology decisions on paper before the build starts.

Before you enquire

Flutter questions to settle before you brief us

What drives the cost and timeline of a Flutter app?

Four things drive Flutter app cost and timing: the number of screens and user roles, the backend and third-party integrations the app needs, device features such as camera, maps or push notifications, and how much of an existing system must be matched or migrated. Netofficials sets these out in a written discovery scope with an initial estimate, so scope, assumptions and review milestones are agreed before the build starts.

Who owns the code, and how will we communicate during the build?

You own the source code and IP: the contract confirms IP assignment before the build begins. For communication, your named delivery lead owns day-to-day progress, and we agree the communication window, meeting schedule and update cadence with you up front. Each sprint ends with a client-facing review, and at release you receive documentation and deployment access.

Can we hire Flutter developers, or is Flutter the right choice for our app?

Yes to both. If you want Flutter app developers without a full project, Netofficials offers a dedicated India-based team or staff augmentation that works inside your tools and process. If you want a fixed scope, project delivery covers it. Flutter suits one app on iOS and Android from a single codebase. If native Swift or Kotlin would serve your product better, we will say so after scoping.

Start your Flutter app with a written scope

Send a short brief on the app you want on iOS and Android. We review it, then come back with questions and a written discovery scope covering what the first release includes. A named delivery lead keeps you informed, and the communication window is agreed with you before work starts. If native Swift or Kotlin would suit your product better than Flutter, we will tell you after scoping.
