How much does it cost to develop a Flutter app?

Developers and entrepreneurs are scrambling to build mobile apps, and Statista ranks Flutter among its Top 10 Most Popular Frameworks with cross-platform capability occupying first place.

Cross-platform technologies are an ideal choice if your top priorities for app development include time, cost and efficiency. Cross-platform initiatives are gradually replacing native app development. Flutter stands out as one of the most efficient cross-platform solutions, making it the optimal solution if your goal is creating an app for your business.

Flutter is an open-source mobile application framework that has revolutionized how companies create apps. Many organizations choose Flutter as the framework of choice to accelerate app development. According to Statista, over 42% of developers plan on using Flutter by 2021 for cross-platform app development – making it the most sought-after technology today for app creation.

Flutter’s two primary advantages are its rapid development process and flexible user interface, both of which make the language attractive to developers. As Flutter becomes increasingly popular, so does the question of its cost for application development.

Google provides Flutter as an open-source Software Development Kit (SDK), used for developing cross-platform desktop and mobile apps similar to Xamarin or React Native. Flutter supports at least six operating systems such as android, iOS, Windows Mac OS Linux & Google Fuchsia; all are capable of supporting apps created using Flutter.

What is Flutter?

Google’s Flutter framework is a free and open-source SDK designed for building mobile applications, specifically Android and iOS phones. From one codebase we can build both web and desktop versions of an app using this technology. Flutter features beautiful widgets along with rich motion APIs which ensure smooth performance on both devices; scrolling, navigation, fonts are cross-platform allowing smooth performance on Android and iOS. Natively compiled Flutter applications offer even higher performance speeds.

Flutter is an all-in-one software platform designed to enable the creation of dynamic cross-platform apps across mobile, web, desktop and embedded devices. Ideal for businesses that wish to redesign existing applications or create platform-independent natively compiled solutions quickly and cost effectively, Flutter makes creating dynamic cross-platform apps effortless and accessible to every employee.

Costs of Flutter App Development: 8 Factors to Keep in Mind

There are eight key considerations when developing a flutter application:

Complexity of the App

The complexity of your app has an impactful influence on its cost – simple ones with limited features will cost less than more complex apps with many functionalities.

Example applications that display weather forecasts could cost between $15,000 and $20,000. A social media app with messaging, user profiles and image sharing could cost as much as $100,000.

Complexity can also impact app development time: simple apps may take only several months while more involved ones could require up to 12 months for completion. As costs associated with Flutter app creation increase, so will development times.

App Size

An application’s size is determined by how much information and data it holds as well as features. A complex app will typically cost more to develop; smaller apps typically require less resources.

  • Features and screen size: Cost increases as features and screen sizes increase.
  • Binary Size: The file size of an installed binary app. 
  • Disk Usage: How much space the app occupies on the device in terms of data it stores.
  • RAM Usage: RAM usage refers to how much memory an app uses while running, while package size refers to how big its download from an online store was.
  • Lines Of Code (LOC): E-commerce systems will typically require more lines than video games; though this doesn’t hold true in every instance; rather it serves as an average benchmark.

Features and Functionality

The cost of custom flutter app development can be determined by features and functionality of an application, with more complex apps incurring increased development costs as more features and functionalities are implemented into their design.

Implementing complex features, such as machine learning and artificial intelligence, requires knowledge and extensive coding expertise. As development costs are increased by adding multiple databases, payment gateways and third-party APIs into the mix, these costs also escalate quickly.

Costs may increase if you add custom UI/UX designs, animations and interactive elements that require extensive design and coding knowledge; their implementation takes time to implement which only adds to their cost.

Integration with Other Systems | Flutter App Development

One way of cutting costs associated with developing a flutter application is integrating it with other systems, although technical expertise will likely be necessary to successfully do this.

Integration of multiple payment gateways requires an in-depth knowledge of each gateway. If requirements aren’t documented, however, this could become difficult and cause higher development costs.

Integrating with databases such as SQL, NoSQL or other can increase development costs significantly. Integrating involves designing the database structure as well as writing and testing queries against it.

Assure data privacy and security. Integrating with third-party services may increase development costs; as part of their API integration process, ensure seamless API integration is understood and ensured smoothly.

Design Requirements on Platform (iOS, Android or Both) 

An app’s design requirements and platform decisions can have a major effect on its look and feel, as well as impact the time and resources necessary for its creation.

Understanding both platforms is necessary when creating apps for both iOS and Android, which can be an intensive and lengthy process that consumes numerous resources while increasing development costs. If the app is designed solely for one platform, costs and development time will decrease accordingly.

Statista Research indicates that Flutter-based cross-platform development is becoming more mainstream. According to their survey, 42% of software developers use Flutter while only about one third of flutter app developer utilise cross-platform technologies or frameworks; native tools remain more commonly used. Furthermore, 41% of apps for Android and 11% for iOS can run concurrently according to this research.

Number of screens and pages

Apps involving multiple pages and screens will take more time to develop than ones containing only two buttons per screen – but having only one page that contains only two buttons may actually cost less!

Simple apps with few pages and screens tend to incur lower development costs; more complex features may incur greater expenses. Each page must feature its own distinct user interface and functionality for optimal use by end users.

Timeframe for Development

The development time frame can have a substantial effect on the cost to create flutter app and flutter app design services, with higher costs leading to longer development times and additional pricing models such as cost model based on time

Fixed-price contracts App development time-based contracts are agreements between clients and development teams whereby clients pay developers for their time and efforts dedicated to creating an app, regardless of its success in terms of results. Payment typically follows hours worked.


Competition among app developers today is fierce! In order to stand out, your app needs to be extraordinary and powerful enough to draw users in. Flutter can help turn a startup idea into revenue-generating apps by offering user-friendly development of cross-platform apps with interactive UIs for both Android and iOS users without hassle.

Flutter mobile app development enables organizations to build native-like apps quickly and affordably on both Android and iOS, publishing simultaneously. As a mobile application development company, we can assist your business goals by designing the highest quality mobile applications.

Flutter can be an ideal platform for developing mobile applications, being easy to create, cross-platform and high performance. Flutter offers great opportunities for all organizations ranging from smaller enterprises up to large ones to gain visibility on both iOS and Android without breaking their pockets.
