The secret of Flutter’s popularity lies in its universal codebase. Developers use it to build native iOS and Android apps fast and efficiently. But how much does Flutter app development cost? And how to find a reliable tech partner to make a big entrance?
“Our goal with Flutter is to fundamentally change the core question from worrying over which platforms to support to a pure focus on what you want to build, ” mentions Michael Thompsen, the product manager at Google, who works on Dart and Flutter, at the Google I/O conference in May 2005. And we know what he means. Flutter is a popular cross-platform app framework that allows developers to create mobile and desktop apps with high performance and intuitive UIs. With Flutter, your apps are compatible with any platform.
Another sphere of Flutter application is its integration with blockchain technologies and smart contracts to create dApps. For example, Flutter serves as the front-end framework for dApps, while smart contracts are written and deployed on blockchains using languages like Solidity. PixelPlex is a dApp development company with more than 12 years of experience in blockchain. Our experts agreed to consult us on the key benefits of the Flutter mobile application development, Flutter pricing, and ways of cost optimization. Let’s dive in.
Why choose Flutter for app development?
30% of new free apps that appear in the App Store are created with the help of the Flutter SDK. Developers continue to choose Flutter for cross-platform app development for a number of reasons. Let’s plunge deeper into the history of Flutter, its features, and its strong sides.
The evolution of Flutter
- 2015-2016: The origin of Sky
Flutter began its history as a project named “Sky” in 2015. Its aim was to run Dart code at 120 frames per second, which was twice as fast as the standard 60 fps for rendering visuals, animations, and interactions. In 2016, Google introduced the project as Flutter at the Dart Developer Summit. - 2017: Alpha release
Google released the first public alpha version of Flutter, showcasing basic functionality and attracting developer interest. - 2018: 1.0 release
In December 2018, a stable version of Flutter 1.0 was released for iOS and Android apps. The key features appeared like “hot reload” for real-time code updates without losing app state. - 2019: Flutter 1.2
Flutter 1.2 improved stability and widgets and introduced the first preview of web support, expanding Flutter’s reach beyond mobile. - 2021: Flutter 2.0
This one is a major milestone. Flutter 2.0 brought stable web support, expanded platform compatibility (iOS, Android, Windows, macOS, Linux), null safety, and improved rendering capabilities. Flutter became a true cross-platform framework. - 2022-2025: Ongoing enhancements
Subsequent versions introduced support for newer OS features, multi-device debugging, improved UI tools, performance optimizations, and deeper integration for desktop, web, and embedded devices.
Following Flutter’s evolution, we see that it has undergone a serious transformation from a mobile-focused toolkit to a versatile framework for building apps across multiple platforms using a single codebase, trusted by developers worldwide.
Key benefits of Flutter
We’ve come to the most interesting part. Why is Flutter application development so popular? It offers key advantages that businesses and developers benefit from.
- Single codebase for multiple platforms: Flutter lets developers write one codebase for mobile app development services, web, and desktop solutions. Flutter’s code runs seamlessly on iOS, Android, Windows, macOS, and Linux. It cuts development time, resources, and experts’ efforts. An app becomes available to wider audiences and brings new revenue streams to a business owner.
- High performance: Google’s new Impeller engine helps Flutter apps run animations smoothly and quickly by converting code into native ARM instructions and using graphics tools like Metal and Vulkan. The Dart programming language lets developers build apps for multiple platforms with one codebase. Flutter also uses the Skia graphics engine to render animations fast and smoothly. Together, these technologies make apps feel faster and work well, even on less powerful devices.
- Faster development cycles: Flutter’s “hot reload” feature enables developers to see code changes instantly without full recompilation. This feature accelerates prototyping, debugging, and iteration, and helps companies bring products to market quickly.
- Rich and customizable UI: Flutter includes a vast ecosystem of widgets and packages that allow building beautiful, responsive, and brand-consistent user interfaces adaptable across platforms. Besides, the widgets allow developers to follow platform-specific guidelines. Dynamic interfaces are possible due to easily combined widgets and elements, which create a layered architecture.

Flutter mobile app development tools and integrated development environments (IDEs) help to build modern and responsive apps. Software experts may choose, for example, Visual Studio, Eclipse, Android Studio, etc.
Testing
Flutter provides developers with testing frameworks for unit, widget, and integration testing. However, you must still test on real devices for each platform to ensure compatibility. Unique integrations or custom plugins may also require extra, specialized testing. Testing frameworks and tools might add $1,000–$2,500 to the budget.
Deployment complexities
Google Play and Apple App Store have their own requirements for packaging, compliance, and metadata. Submitting, reviewing, and fixing any rejections takes time and can incur costs for specialized DevOps or CI/CD setup. Deployment and launch activities generally run from $1,000-$5,000 for most apps. This covers app store registration fees, server setup, and effort to ensure smooth roll-out. Highly complex multi-platform deployments (web, desktop, custom devices) may cost more due to additional setup and quality checks.
| Platform | Fee type | Cost (USD) | Notes |
| Google Play Store | Developer account fee | $25 (one-time) | One-time registration fee to create a developer account |
| In-app purchase fees | 15% for first $1M revenue, then 30% | Commission on in-app purchases or subscriptions via Google Play billing | |
| Review time | 1-3 days | Review process time for app approval | |
| Apple App Store | Developer account fee | $99/year | Annual fee for Apple Developer Program membership to publish apps |
| In-app purchase fees | 15% for first $1M revenue, then 30% | Apple’s commission on in-app purchases and subscriptions | |
| Review time | 1 week average | App review takes longer depending on app complexity and compliance |
Ongoing maintenance
The final Flutter mobile development cost is worth calculating after the launch and including the maintenance expenses. These are adding new features, updating the app to the latest OS versions, fixing bugs, etc. It also covers responding to user feedback, monitoring analytics, and iterating on feature requests. Expect ongoing support and maintenance to run 15–25% of your initial development cost per year.
Avoiding costly mistakes
Here are some tips on how to optimize your Flutter mobile development costs.
- Develop only core functionality. Create an app with the features that are necessary for the users to solve their issues. Therefore, your app will bring high customer satisfaction at a low cost.
- Follow an agile strategy. Building an app by small parts and testing every one of them allows for timely bug fixing. You won’t need to restart the whole development process if a flaw appears at the final stage.
- A minimal viable product (MVP) will shorten the time to the market and provide you with the first user feedback. You will add features if the real customers demand it.
- Outsourcing the development services helps cut costs and time. Reliable tech partners cover the whole cycle of creating an app from start to finish. You will also receive competent IT consultants who will be able to suggest best practices.
MVP development services are beneficial for businesses as they receive early feedback from their users and potential clients. This feedback guides product improvements, helping you avoid over-engineering and costly full-scale development of features that might not be needed. Early validation also allows you to understand if the market needs your product.
Second, an MVP focuses on must-have features, which reduces initial development time and expenses.
Finally, a working MVP attracts investors. They prefer tangible products with validated demand over ideas alone. Your MVP will demonstrate the concept’s viability and market interest.
