Financial App on Flutter: Why Choose This Framework to Power Your Next Fintech Project?

If you’re thinking about creating your own Flutter financial app, you’ve come to the right place. The fintech market is constantly expanding, and the value of digital payments worldwide is expected to hit nearly 9.5 trillion USD in 2023. 

It can be a profitable sector to enter, but it also comes with its own technical challenges, from data protection requirements to design standards. 

One way to handle these issues is selecting the right framework for the job. Let’s talk about why companies like Google Pay and Nubank opt for Flutter over native development and other frameworks.

What makes Flutter and financial apps a perfect match

Initially released in 2017, Flutter is a cutting-edge cross-platform framework. It offers all the benefits of cross-platform workflow without any of the typical shortcomings. Here’s what makes Flutter the right choice for financial apps:

1. Cost-efficiency and speed

Deploying from one codebase to six basic platforms is a major benefit: based on our experience, it can save you up to 40% of the time and money you’d otherwise spend on native development.

2. Futureproofing

Flutter will likely surpass React Native as the most used cross-platform framework in 2023. Since it’s an open-source project led by Google, there’s a massive community behind it that continues to develop new libraries and workflows. It also means that some of the best developers in the world actively maintain the framework. This is one of the aspects we adore so much at Surf, and we actually contribute to Flutter’s SDK, having submitted over 30 packages.

3. Scalability

Flutter allows developers to create efficient code which is easy to maintain and scale. Building a strong foundation with the right tools will  help you avoid problems and unnecessary expenses later on, even if scalability isn’t your priority now.

We once received a Client request to optimize their existing native app. The codebase was outdated and failed to meet the fast-changing market requirements. Having discussed the job with the Client, we saw that shifting the app to Flutter and modernizing the codebase would be quicker and cheaper for the bank, than reworking it. 

As a result, we created a new Flutter financial app from scratch, improving the UX. We also increased the testing speed by 10 times.

Flutter financial apps: case studies

Let’s take a look at the challenges which Flutter helped us solve in real-world projects.

Creating the first Flutter banking app in Europe

We built a cutting edge Flutter banking app for business.

The mission was to make a user-friendly, intuitive, and responsive UI for a very complex product — a bank specializing in handling multiple legal entities. This interface had to also integrate with a legacy backend system.

Flutter’s UI system made accessing key features only a tap away. By using this system, we were able to transfer all of the Client’s current customers over to the new application without having them go through a sign-up process again.

Developing a Neo Bank app for a Y Combinator startup

Our mission was to create a neo-banking super app for a Y Combinator-backed startup with an estimated value of $100 million.

The challenge was to develop a financial application in a rapidly changing environment, while still maintaining agility, and launch it quickly. 

We succeeded by fusing a custom cutting-edge frontend with backend SDKs and services to handle routine operations. 

Thanks to how quick Flutter financial app development is, we were able to quickly iterate on features and design concepts and build a super app in under a year.

Wrapping up

Flutter is an awesome tool for building financial apps. It’s cross-platform, saves time and money, has a huge community, and is easy to scale. At Surf, we have used it to complete complex fintech projects for clients.
