Flutter App Development

What's included

Every Flutter project at Cartel Planet is delivered as a complete product, not just a code drop. You get a discovery workshop, user flows and a clickable prototype, UI design for both platforms, Flutter development with a clean, maintainable architecture, an admin panel to manage your content, users and orders, backend and API integration, payment gateway setup (Razorpay, PhonePe, Cashfree or Stripe), push notifications, analytics, crash monitoring, testing on real Android and iOS devices, Play Store and App Store submission, and a three-month stabilisation window after launch.

When the project ends, everything is in your name: the source code repository, the developer accounts, the signing keys and the hosting.

Who is Flutter App Development for?

Flutter is the right choice when you need to be on both Android and iOS without paying for two separate apps. It suits:

• Startups launching an MVP who need to test the idea with real users on both stores before the runway runs short.
• Small and mid-sized businesses that want a customer app for bookings, orders, loyalty or service requests.
• D2C and retail brands moving repeat buyers from marketplaces to their own app.
• Companies with field teams that need an internal app for sales, delivery, attendance or inspections that works offline.
• Businesses with an outdated app who want to rebuild on a modern stack instead of maintaining two ageing codebases.

What we offer

• Flutter MVP development – the core features you need to launch, validate and raise, built in 10–14 weeks.
• Full-scale Flutter apps – customer apps, marketplaces, booking platforms, delivery apps, fintech and edtech apps.
• Enterprise and internal apps – field-force, CRM, inventory and approval apps connected to your existing systems.
• Native to Flutter migration – move separate Android and iOS apps into one codebase without losing users or data.
• Flutter UI/UX design – screens designed to feel native on both platforms and tested with users before build.
• Backend, admin panel and APIs – Firebase, Node.js or Laravel backends with a dashboard your team will actually use.
• App maintenance and care plans – OS updates, Flutter version upgrades, new features and monitoring after launch.

What makes our Flutter App Development different

Most app projects in India go wrong in the same three places: vague quotes, invisible progress and an app that breaks the week after launch. We built our process to close all three.

You get a fixed price in writing before work starts, not an hourly meter. You see a clickable prototype before development, so changes cost minutes rather than weeks. You get a weekly demo on a live staging build that you can install on your own phone. And we stay on for a three-month stabilisation window with crash monitoring, fixing what real users find.

We also build for Indian conditions: apps that load on mid-range Android phones, work on patchy networks, support UPI payments and handle regional languages where you need them.

Our process

Understand, plan, design, build, test, launch and grow. Each stage has a clear output you sign off before we move on, so there are no surprises on cost or timeline. The full process is set out below.

Benefits

One codebase means roughly one team, one budget and one release cycle instead of two. You reach Android and iOS users on the same day, ship updates to both at once, and spend less on maintenance every year after launch. Flutter compiles to native code, so your users get smooth scrolling and fast screens, not a slow web wrapper.

Why Choose Cartel Planet

We're an Indian team of designers, Flutter developers and marketers who measure a project by what happens after launch: installs, retention, orders and enquiries. Pricing is published and transparent, you get a GST invoice, you own everything we build, and you can reach a real person on call or WhatsApp. If Flutter isn't the right fit for your app, we'll tell you in the first call and recommend native instead.
