Flutter app development

Get native-looking, high-performing cross-platform apps with just one codebase

When to choose Flutter app development

Flutter is one of the most popular solutions these days when it comes to building cross-platform and mobile apps. And no wonder – it helps speed up the app development process, optimize development budgets, and end up with apps that have a native look and feel, no matter the platform.

Flutter is Google’s open-source framework for building beautiful, natively compiled, multi-platform applications using a single codebase (or so they say on their website ;)). And that single codebase is key here – wherever you want your app to work, you don’t have to build a separate version each time. With one codebase, you can reach people using different devices and different screens, including web, desktop, mobile, and embedded devices.

And what does that mean for your business? You guessed it. With one codebase to build and update, Flutter app development essentially means faster time to market and easier cross-platform updates, a broader audience, all combined with high performance, rich features, and visual appeal.

It’s a great solution when you want to be flexible with your app, cater to users in different markets, and make sure you’re spending your app development budget wisely. Flutter app development usually means there’s one software developer involved instead of several developers each specializing in different platforms. And, as an open-source and widget-based framework, it has an active community of developers constantly perfecting it.

Which is exactly why DeSmart developers specialize in Flutter app development services, helping companies build feature-rich, great-looking apps in a fraction of the usual time. 

The benefits of custom Flutter development

  • Cross-platform apps

You’re building one app for many platforms – iOS, Android, web, and desktop – with native look and feel and a single codebase. The latter meaning less time spent on app development and faster time to market. 

  • Shorter development timelines

As a result of the cross-platform approach and available widgets, the app development process takes less time, as you’re not building a separate app for each platform and screen.

  • Faster testing

Flutter allows for a much more efficient collaboration between software developers and QA engineers, so that they can make changes on the go, fix bugs, and see results much quicker than you normally would. 

  • Optimized development budget

Because you spend much less time creating and testing the app, you’re also going to save money on app development, without having to hire multiple developers for multiple versions of your app.

  • Easy maintenance

Because the apps for different platforms share the same codebase, it’s easier (and faster) to maintain, update, and grow them. Giving you much more flexibility and scalability in business growth.

  • Used by billions of app users

Flutter was built by Google and is used by apps like Google Ads and Google Assistant, eBay Motors, or the Weight Tracker app.

What our clients say about our mobile web development services

DeSmart Software Development has succeeded where several other companies have not. I started this project with a certain vision of what I wanted, but no other companies have been able to provide me with what I wanted. With DeSmart Software Development, I have gotten what I wanted and more.
We received a great deal of effort for our money, and I’m happy with our collaboration. The quality of work was professional, and their team identified any bugs by themselves most of the time. Based on the ideas we provided, they came back with an improved solution. They also gave us extra product functionalities.
The initial meeting we had with DeSmart before we started the project was really effective. I recommend doing so if you have the opportunity. Also, their communication, speed of development, and expertise were impressive. DeSmart was excellent at providing their own ideas, which benefited the project greatly.
DeSmart is synonymous with service quality. The company works in a truly agile mode, regularly delivering work increments, which allows to quickly and easily synchronise on requirement details. I was especially impressed with the dev team’s capability to quickly learn and start using our new APIs.
I’d highlight that their ability to adapt is exceptional. We didn’t go with a fixed scope and ended up with a different product than we’d had in mind. They were accommodating of changes and adjustments. That made them very easy to work with. They were also very transparent about pricing, which we appreciated.
I was impressed with their developers' efficiency, speed, and flexibility . Cooperation was smooth and uninterrupted. Monitoring of resource consumption to be improved. Great culture fit. Good value for cost. Company values aligned.


We realize you might not be familiar with all the aspects of the software development process. So here are a few pointers and explanations you might find helpful. And if you have more questions, send us a message, and we’ll get back with the answers.

What are the first steps when we start working together?

1.We always start with consulting your project with our product and business teams to see if we’re indeed a good fit.

2.We’ll then create a cost estimate and a proposed timeline.
Then we’ll organize workshops to help us define the business and product requirements so that we can build the best software solution for your needs. The people who took part in the workshops will make up the foundation of your project team.

3.We sign the contract and set up a kickoff meeting to nail down all the project details.

What are the benefits and drawbacks of the technologies you use?

Our development team will talk you through all the benefits and drawbacks of a specific technology for your specific project so that you know all you need to know to make your decision before you actually make it.
One of DeSmart’s core values is transparency, and we always inform our clients about any risks involved.

Will I work with a dedicated contact person on your team?

This really depends on your requirements. We have project managers, testers, and developers on board, and everyone’s equally involved in the project. This means you can talk directly to the developer working on your software and avoid the usual miscommunication that can happen when information travels through the hands and keyboards of multiple people.

Do you use project management software like, e.g. Jira?

Yes, we communicate using Slack and Jira and try not to use email too much. We’re also open to adjusting to the tools your company uses.

Are you a stable company?

Oh, we are. In the past 19 years, we’ve completed over 200 projects and have a full-time in-house team of about 30 people. We’re also the founding members of sodapl.com – the Polish Software Development Association. Go to https://clutch.co/profile/desmart to read what our current and past clients have said about working with us.

Why would I want to work with you?

We’re a boutique software house hiring a maximum of 30 people. Among other things, this means that your project is always a priority for us – we just can’t take on too many projects at a time. We’re also super honest and transparent and will always give you a clear picture of what’s going on.

Our team includes experts with many years of experience, and we’re often asked by other software houses to support them with their projects.

We also have a unique company culture. We’re teal-oriented and value a human approach to software development (which is why “Human-first software development” is our tagline) and work in general. And you can see it both in how we run the company and the way we work with our clients.
