Flutter app development from the team that built UpTrendPos. One code base gives you an Android app, an iPhone app, a web app and Windows desktop software, designed, built, published and supported by AGRSoft.

FlutterMost businesses do not need four separate apps built by four separate teams. They need one product that works on the phone in a customer's pocket, on the laptop in the office and in the browser. Our Flutter app development service delivers exactly that, from a single code base that is cheaper to build and much easier to keep up to date.
Flutter is Google's open-source toolkit for natively compiled apps. Apps are written once in Dart and compiled for Android, iOS, the web, Windows and macOS. Screens look and feel the same everywhere, and new features reach every platform at the same time.
We do not just talk about Flutter. Our own product, UpTrendPos POS software, is a Flutter app used by shops for billing, stock and accounts. It runs on Android, Windows and the web, keeps working offline and syncs when the internet returns. The same experience goes into every client app we build.
Because AGRSoft also designs websites and runs SEO and social media marketing, we can launch your app with a landing page, store listings that rank and a campaign to get the first downloads.
One code base, four kinds of app. Pick the platforms you need now and add the others later without starting again.
Apps for Android phones and tablets, tested on real devices and published to Google Play.
iPhone and iPad apps from the same code, tested on TestFlight and published to the App Store.
Customer portals and admin dashboards that run in any browser, with no install needed.
Windows desktop software for shops, offices and counters, including offline mode.
Food ordering, delivery and shopping apps with carts, payments and live order tracking.
Billing, stock, staff and accounts, built on the same foundations as UpTrendPos.
Appointments, classes, memberships and reminders for salons, clinics and gyms.
The back end your app needs: database, sign-in, roles, notifications and reports.
One Flutter code base, written in Dart, gives you native apps for phones, a web app and desktop software. Here is what we build with.
Google's UI toolkit for natively compiled apps from a single code base.
The fast, type-safe language Flutter apps are written in.
Apps for Android phones and tablets, published to Google Play.
iPhone and iPad apps built from the same code and published to the App Store.
The same app running in the browser, for customers or admin dashboards.
Desktop software for shops and offices, including offline use.
Sign-in, push notifications, crash reports and analytics.
Postgres database, authentication and real-time sync, the stack behind UpTrendPos.
Store listing, screenshots, testing tracks and release management.
App Store Connect setup, TestFlight testing and Apple review.
Flutter is used by companies of every size, and it is backed by Google with regular stable releases. For most business apps it offers the best balance of speed, cost and quality.
Instead of separate Android, iOS and web projects, one team builds one app. That usually cuts build time and makes every future change cheaper, because it is made once.
Flutter compiles to native machine code and draws every pixel itself, so scrolling, animations and screens stay smooth on older phones too.
Flutter does not force a generic look. Colours, fonts, icons and animations match your brand on every screen and every platform.
With a local database on the device, apps keep working without internet and sync later. This is how UpTrendPos keeps billing running when the connection drops.
| What matters | Flutter | Separate native apps |
|---|---|---|
| Code bases | One | One per platform |
| Time to launch | Faster | Slower |
| Build cost | Lower | Higher |
| Same design everywhere | Yes | Harder |
| Web and desktop | Included | Extra projects |
| Performance | Native compiled | Native |
| Future updates | Once for all | Repeated |
Case study, our own product
We designed and built UpTrendPos, a multi-tenant POS system for retail shops, pharmacies and chains. It handles billing, barcode scanning, stock, purchases, customer credit and double-entry accounts, with an owner dashboard and thermal receipts.
Client work
For restaurants we built a complete food ordering system in Flutter: a customer app, a web ordering site and a management dashboard working from the same data.
Four clear stages, with a working build in your hands early and your approval before anything goes to the stores.
We map users, screens and features, choose the back end and send a fixed quote and timeline.
Free consultationClickable screens for phone, tablet and desktop, so you see the app before code is written.
Your feedback includedTwo-week sprints with test builds on your own phone, plus testing on Android, iOS and the web.
Regular demosWe publish to Google Play and the App Store, deploy the web app and keep it updated.
Support after launchEvery app is different, so every quote is fixed and written for your project, in USD or PKR.

Flutter app development means building an app with Flutter, Google's open-source UI toolkit. The app is written once in the Dart language and compiled into native apps for Android and iOS, a web app and desktop software for Windows and macOS.
Yes. That is the main advantage of Flutter. We build one code base and release it to Google Play, the App Store, the browser and Windows. You choose the platforms you need now and can add the others later.
A focused first version (MVP) usually takes about 6 to 8 weeks. A business app with an admin dashboard, payments and notifications typically takes 2 to 4 months, depending on the number of screens and integrations.
Cost depends on screens, features, platforms and integrations. Because one code base covers every platform, Flutter is usually cheaper than building separate native apps. Send us your idea for a fixed quote in USD or PKR.
Yes. We prepare store listings, screenshots and privacy details, upload test builds, handle Google and Apple review and publish the app under your own developer accounts.
Yes. With a local database on the device, a Flutter app can save data offline and sync when the internet returns. Our own UpTrendPos POS software works this way.
You do. The source code, designs, store accounts and back-end accounts are yours once the project is paid. We can keep supporting the app or hand it to your own team with documentation.
