Shared
Build once, release on both platforms.
Business logic, screens and tests are written a single time in Dart. Platform differences such as permissions, notifications and store rules are handled where they genuinely differ.

Flutter app development company
Flutter app development, one codebase, two app stores.
CodingMarble is a Flutter app development company in India that designs and builds Android and iOS apps from a single codebase, working remotely with startups and established businesses through a guided brief and client portal.
Flutter draws its own interface instead of borrowing the widgets of each platform, so a screen looks and moves the same on a budget Android phone and a new iPhone. For most business and consumer apps that means one team, one release cycle and one bill.
Distinctive
Interfaces that do not look stock.
Because Flutter controls every pixel, brand typography, custom charts and fluid transitions are straightforward, without fighting two separate native toolkits to get the same result.
Predictable
Fixed app packages in USD.
Apps start from USD 480 for a focused three-screen product on one platform, with larger packages for sign-in, notifications and commerce, shown in your own currency.
Flutter vs React Native vs native
When Flutter is the right framework, and when it is not.
Flutter suits products where design consistency and delivery speed matter: booking and service apps, fintech dashboards, education, fitness, community and internal field tools. Startup app development benefits in particular, because one codebase lets a small budget reach both stores and change direction quickly after the first user feedback.
It is not always the answer. If your web product is already React and your developers will maintain the app, React Native lets them reuse skills and logic. Apps built around heavy platform features, such as advanced camera processing, background Bluetooth or the newest operating system widgets, are often safer in native Android and iOS code.
- Strong for MVPs and service apps
- Identical design on every device
- React Native for React-based teams
- Native for deep hardware features
Design and performance
Smooth on the phones your customers really own.
Flutter compiles to native machine code and renders through its own graphics engine, so scrolling and animation hold up well on mid-range Android hardware, which is what most users in India and many other markets carry. Screens are tested on inexpensive devices as well as flagships, on slow networks as well as office wifi.
Flutter app development services here include the states that are easy to forget: first launch, no connection, expired session, empty lists, permission refused. Local storage keeps essential screens usable offline, images are cached, and app size is watched because large downloads are abandoned. Analytics and crash reporting are wired in before release.
- Compiled to native machine code
- Tested on budget Android phones
- Offline and error states designed
- App size kept under review
Cost and launch
Flutter app development cost, stated before you pay.
Three fixed packages cover most first releases. The Basic App is three screens on a single platform. The Standard App adds sign-in, profiles, push notifications and analytics, with cross-platform delivery available. The E-commerce App brings catalogue, cart, payments, wishlist and order tracking. Anything beyond them is quoted individually in a written scope.
Launch is part of the work. Store listings, screenshots, privacy declarations and review submissions are prepared, and apps can be published under your own Apple and Google developer accounts so ownership is never in doubt. Those accounts carry their own fees, payable to Apple and Google. Source code is handed over after final payment.

- Custom scope for larger products
- Store listings and submission handled
- Published under your own accounts
What is covered
What a Flutter build can include.
Screens are only part of an app. These are the pieces that normally appear in the written scope.
UX and interface design
User flows, wireframes and a finished visual design in your brand, agreed screen by screen before development so there are no surprises later.
Cross-platform Flutter build
One Dart codebase producing Android and iOS apps, structured with clear state management so another developer can extend it without guesswork.
Back end and API
A Node.js or PHP API with database, admin dashboard and authentication, or a secure integration with a back end you already run.
Sign-in and notifications
Email, OTP, Google or Apple sign-in, plus push notifications with topics and deep links that open the correct screen inside the app.
Payments and commerce
In-app checkout through a payment SDK using your provider credentials, with order history, promo codes and receipts where the product needs them.
Testing and store release
Device testing, crash reporting, store assets and submission to Google Play and the App Store, followed by a period of post-launch fixes defined in scope.
Fixed packages
Fixed app packages a Flutter project can start from.
Prices are fixed in USD and shown in your own currency. The written quote confirms scope, delivery target and payment schedule before you pay.
