What we do
Flutter development services
What we do with Flutter, from a new app and its back end to store releases and the support behind them.
Book a free Flutter consultation
-
One codebase for both stores, built around the few things your users must be able to do.
-
Node.js, Laravel or Firebase back ends, or a clean connection to the API you already run.
-
A web panel to manage users, orders or rides, with the reports your team needs.
-
Screens and flows designed before the build, so changes are cheap and sign-off is clear.
-
Takeovers and upgrades
Flutter apps another team wrote, brought up to date with the current SDK and packages.
-
TestFlight and Google Play testing, store review, then fixes, OS updates and new releases.
Choosing how to build
Flutter, React Native or native?
We build apps all three ways, so we have no reason to push you either way. This is how we help clients choose.
-
Choose Flutter when
- You need iPhone and Android apps from one team and one codebase
- Your app has its own branded look, with custom screens and motion
- You want both store releases to ship together
- You may want a web or desktop version from the same code later
-
Choose React Native when
- Your team already writes React and JavaScript or TypeScript
- You want to share code and people with a React web app
- You prefer each platform's own built-in controls
-
Choose native Kotlin or Swift when
- The app leans on device hardware: Bluetooth, sensors, background work
- You need only one platform, or a new OS feature on the day it ships
- You already have a native app and a native team

How we work
From first call to an app in both stores
Six steps, and the same way of working on every app.
Flutter development
What we build with Flutter
The development work behind an app people keep using, and the parts around it. Where a project in our case studies shows it, the card links to it.
-
B2B ordering apps
Sign-in by phone number, stock by pincode before the cart, search and reorder from history, for shop owners new to apps.
TrueWholesale → -
Ride-hailing and booking apps
Rider and driver apps with live location, arrival times, in-app chat and calling, and rides drivers accept or reject.
Pro Taxi → -
Admin panels behind the app
A panel to manage users and drivers, see every booking and its status, run promo codes and track revenue.
-
Payments and subscriptions
Plans, credit bundles and checkout inside the app through Razorpay and Apple In-App Purchase, with card details kept with the gateway.
Chitra → -
Apps on your back end
Flutter apps that call a Node.js or Laravel API or Firebase, with sign-in, live stock or orders, and push notifications.
-
AI assistants in the app
Questions asked by text or voice and answered by an AI backend, in Hindi, Hinglish and English, with the results shown as cards.

Speed, security and care
Fast, safe and kept up to date.
An app keeps changing after it reaches the stores: new iPhone and Android versions, new store rules, new Flutter releases and more users. We look after the app and the back end it calls, before launch and after it.
-
Smooth on everyday phones
Screens profiled on real devices, images sized for phones and long lists loaded as the user scrolls.
-
Updates without surprises
Flutter, package and OS updates tried in test builds first, and store requirements kept current.
-
Crash reports and alerts
Crash reporting in every release, so a problem is seen and fixed in the next build.
-
Security basics, done
Sign-in tokens stored securely, API calls over HTTPS, secrets kept out of the app. Card details stay with the gateway.

FAQ
Flutter development questions
Straight answers, with the project behind each one.
How much does Flutter app development cost?
It depends on the screens and kinds of user, whether you need iPhone, Android or both, the back end, the integrations and the design. We do not sell fixed packages. After a short call, we send an approach, a rough timeline and a rough cost range within two working days, with no charge and no commitment.
How long does it take to build a Flutter app?
An app with a handful of screens on an existing API takes far less time than rider, driver and admin apps with a new back end. We give you a realistic timeline after the first call, and you try the app on your own phone through test builds as it is built.
What is Flutter?
Flutter is Google's open-source toolkit for building apps from one codebase, written in the Dart language. The same code compiles to native apps for iPhone and Android, and can also target the web and desktop.
Should I choose Flutter, React Native or native Kotlin and Swift?
We build with all three, so the answer depends on your app. Flutter suits iPhone and Android apps from one codebase with a branded look; React Native suits teams that already write React; native Kotlin or Swift suits apps that lean on device hardware or need only one platform. We tell you which fits after the first call.
Will a Flutter app feel right on both iPhone and Android?
Yes. Flutter draws its own screens, so your design looks the same on both, and it has iPhone-style and Android-style controls where you want each platform's feel. Device features such as the camera, location and notifications are reached through plugins.
Can you publish the app on the App Store and Google Play?
Yes. We send test builds through TestFlight and Google Play testing, prepare the store listings and take the app through review. TrueWholesale's retailer app is live on both stores and still updated.
Which back end do you use with a Flutter app?
Whatever fits the app. TrueWholesale's app runs on the Laravel ordering platform we built, Pro Taxi on Firebase, and Chitra and Gyanee.ai on a Python AI backend. We also build Node.js back ends for apps. If you already have an API, the app can call it.
Can you take over or update an existing Flutter app?
Yes. We read the code, get it building again, add tests around the parts that break most, then move it to the current Flutter SDK and packages step by step and release it to both stores.
Who owns the code?
You do. The code goes into your own repository as it is built, and we recommend the app is published under your own Apple and Google developer accounts, so it stays yours if you ever change teams.
Do you work with clients outside India?
Yes. Our team is in Jaipur on IST, 4.5 to 5.5 hours ahead of London and 9.5 to 10.5 ahead of New York, and works with clients in the US, the UK, Europe, Australia and the UAE. Our UK company, Provis Global Ltd, is registered in the United Kingdom.
