Cross-Platform Excellence

Flutter App Development Services

Leverage the power of Flutter to build beautiful, natively compiled applications for mobile, web, and desktop from a single codebase.

Single Codebase

Reach iOS and Android users simultaneously with high-quality apps.

Fast Development

Quick turnaround times with Hot Reload and pre-built widgets.

Native Performance

Smooth animations and high performance that feels truly native.

Why Choose Nimai Solutions for Flutter App Development

One Codebase, Two App Stores

Flutter compiles to native ARM code for both iOS and Android. You get two fully native apps from a single development effort — cutting your budget by 30 to 40 percent compared to building separate native apps.

Pixel-Perfect Custom UI

Flutter's rendering engine draws every pixel on screen, which means we are not limited by platform-specific UI components. Your app looks exactly the same on a Pixel phone as it does on an iPhone — or we can customise it per platform.

Faster Time to Market

Hot Reload lets us see changes instantly during development. Combined with Flutter's rich widget library, we deliver production-ready apps in 6 to 10 weeks — significantly faster than traditional native development.

Google-Backed, Future-Proof

Flutter is Google's primary UI toolkit with over 160,000 stars on GitHub and backing from companies like BMW, Alibaba, and ByteDance. Your investment is protected by one of the most active open-source communities in mobile development.

Our Flutter App Development Process

01

Requirements & Prototyping

We map out your app's user flows, define the feature set, and create interactive prototypes in Figma that you can tap through on your own phone before development begins.

02

Architecture Design

We choose the right state management approach (Riverpod, BLoC, or Provider), define the folder structure, and set up CI/CD pipelines for automated builds and testing.

03

Sprint-Based Development

We build in two-week sprints, delivering working features you can test on your device at the end of each sprint. You see progress every fortnight, not just at launch.

04

API & Backend Integration

REST or GraphQL APIs, Firebase services, push notifications, payment gateways, and third-party SDKs — all integrated and tested for both platforms simultaneously.

05

Testing & Optimisation

Unit tests, widget tests, and integration tests automated in our CI pipeline. We also perform manual testing on 10+ real devices and optimise app size, startup time, and memory usage.

06

Store Submission & Launch

We handle App Store and Play Store submissions including screenshots, descriptions, and metadata optimisation. Post-launch, we monitor crash reports and user feedback for rapid iteration.

Technologies We Use

Flutter / Dart

Google's UI toolkit for building natively compiled applications for mobile, web, and desktop from a single codebase.

Firebase

Backend-as-a-service for authentication, real-time database, cloud functions, analytics, and push notifications.

Riverpod / BLoC

State management solutions that keep your app's logic testable, maintainable, and scalable as features grow.

REST / GraphQL APIs

Flexible backend communication depending on your data requirements and existing infrastructure.

Fastlane / Codemagic

CI/CD automation for building, testing, and deploying to both app stores with a single command.

Frequently Asked Questions

Is Flutter good enough for production apps?

Flutter powers apps used by hundreds of millions of users globally, including Google Pay, BMW, and Alibaba. At Nimai Solutions, every Flutter app we ship passes the same performance benchmarks we set for native apps — 60fps animations, under 2-second cold starts, and sub-100MB app sizes.

How much does a Flutter app cost in India?

A Flutter MVP with 5 to 8 screens, user authentication, and API integration typically costs between 2 to 4 lakh INR. Full-featured apps with custom backends, admin panels, and payment integration range from 5 to 12 lakh INR. We provide fixed-scope quotes after the discovery phase.

Can you convert my existing app to Flutter?

Yes. We regularly migrate native iOS or Android apps to Flutter. We audit your existing codebase, plan the migration in phases, and ensure feature parity before decommissioning the old apps. Most migrations take 8 to 14 weeks.

Does Flutter support web and desktop apps too?

Flutter supports web, Windows, macOS, and Linux targets from the same codebase. For most of our clients, we start with mobile and add web or desktop when the business case is clear — the shared codebase makes adding platforms incremental, not a rewrite.
