What is Flutter Development?

Launched in May 2017, the Flutter framework is Google’s Open Source SDK for building beautiful, natively compiled mobile applications from a single codebase. 

Flutter speeds up software development by allowing developers to build apps for android, iOS, web & desktop using a single codebase. This makes our Flutter app development rapid and cost-effective, which is perfect for start-ups or organisations looking to get to market quickly.

Since its launch, Flutter has been rapidly adopted by top global organisations including Square, Ebay, BMW and Alibaba. 


Our Flutter Services

Bespoke Flutter App Development

Our robust Flutter app development process helps businesses bring their idea to market in record time, without compromising security, performance or quality. We are one of the few specialist Flutter agencies with significant experience building commercial mobile apps using the framework, having worked with clients such as Costa Coffee and Red Bull Racing.

Flutter Desktop

Desktop support means we can also use Flutter to develop native Windows, macOS, or Linux desktop applications, allowing you to support a broader range of users and devices. This desktop support also extends to plugins.

Flutter Migration and Maintainence

Looking to migrate an existing native application over to Flutter to reduce on-going costs and complexity? Our team can support you at every stage of the process, from mapping out technical architecture and integrations to developing custom widgets that replicate native components. We can also help you maintain and further improve an existing Flutter application.

Flutter Consultancy

From long term support, to urgent project recovery, we can offer Flutter Consultancy services to compliment your existing team and platform. Alongside developing and maintaining Flutter apps, our developers are able to provide Flutter audits on platforms of any scale to help you to understand any improvements or further development required.

Flutter Web Development

Web support for Flutter enables existing mobile-based applications to be packaged as a Progressive Web Application (PWA). This allows our team to build solutions that span multiple devices. We can also deliver web experiences for existing Flutter applications.

Flutter Project Rescue

Many of our clients come to us with existing Flutter apps that require urgent support. If your Flutter project has run into difficulties or you’ve fallen out with your existing app developer, we can quickly get you back on track with full code audits and a comprehensive recovery plan.

Why Build Your Next App in Flutter?

Rapid Development

Want to get your MVP into the hands of users quickly or your app to market before the competition? Using Flutters' cutting-edge development features, our developers can quickly experiment, build UIs, add features and fix bugs faster. The faster we build, the sooner you have your mobile application live.

Native Performance

With Flutter, there's no need to compromise on performance or interface quality. Flutter allows for all critical platform differences such as scrolling, navigation, icons and fonts. Delight your users with Flutter's built-in rich motion APIs, smooth natural scrolling, and platform awareness.

Multi-Platform Support

Alongside iOS and Android, Flutter supports the generation of web content. With web support, we can compile existing Flutter code into a format that can be embedded in the browser and deployed to any web server. This allows us to use all the features of Flutter without the need for a browser plug-in.

Our Flutter Development Process


Our comprehensive Discovery process turns business objectives, user profiles, and commercial models into functional specifications and prototypes. This ensures your Flutter app is built on solid foundations.


Now that Discovery has identified the scope of the project and the needs of your users, we start work on delivering a great user experience through design that is focused on utility, ease of use, functionality and empathy.


This is where our mobile developers turn prototypes and designs into reality using Dart, the codebase which underpins Flutter. 


Our highly-experienced QA Engineers exhaustively test and scrutinise our code so it meets our high-quality standards. We only release code that has been through our rigorous QA process to ensure your Flutter app performs flawlessly.
