Flutter application development services

The Flutter framework makes it easier than ever to build, test, and deploy native-like mobile, web, desktop, or embedded apps, exactly the way you want them.

How can our Flutter app development services be of help?

Flutter mobile app development

Flutter is all about creating apps that work smoothly on any device, without making you spend extra on separate versions for iOS, Android, and web. Customers get a seamless experience no matter what device they use, while you get an app that's fast, reliable, and easy to update as your needs grow. That way, cross-platform development can save time, cut costs, and reach the audience more effectively. Did we pique your interest? Our experienced Flutter app developers can create such an application for you - just give us a call, and we'll show you how you can use Flutter to build an outstanding product.

Flutter solution architecture

Building a Flutter architecture at the project start lays the groundwork for a smooth and efficient app development process later on. Having a clear architecture plan in place means you'll understand better how your app should work, and that way, you'll have fewer unpleasant development surprises on the way. This approach can save your business time and money, but also quite a lot of stress since you'll be able to prevent costly project changes midway. Plus, with a solid architecture in place, the app can be built to handle growth and adapt to the future needs of the users.

UI/UX design for Flutter apps

Outstanding UI/UX design is precisely what you need to make a cross-platform app intuitive and enjoyable for users. With a custom design, the new product doesn't just look great—it works exactly how the audience expects, keeping them engaged and enjoying their time inside. Our team of Flutter app developers can craft such a design for your business, one that will both reflect your business's unique identity and be effortless to use, keeping users coming back to the app more often.

Security services for cross-platform app

With our Flutter security services, you can ensure your mobile applications stay safe from cyber threats and that the user data inside it is fully protected from unauthorized access or misuse. Depending on the needs, we can implement features such as biometric authentication or data encryption, and then we will thoroughly test the app to spot and patch any security vulnerabilities we find. We can also test the security during routine maintenance to identify and address new vulnerabilities before they become serious issues. When the app is safe and reliable, your users can feel more at ease using it - and you have one less thing to worry about as well.

Flutter QA and testing

Fixing performance or usability issues after the Flutter mobile app development project has been concluded can be pretty costly. Running the app through detailed testing and QA can help you prevent or minimize such costs though. That's why our Flutter mobile app development services also include Quality Assurance. By carefully testing every part of the app, we can catch bugs or compatibility issues early so they don't cause problems for your users later. During the QA process, we'll also ensure that all features work as planned, that the product performs flawlessly on all platforms, and that it can handle a growing user base and traffic.

App Store/Google Play compliance services

As a part of our Flutter development services, we can also help you handle the compliance requirements for the new app so the app store approval process goes smoothly.  Our team handles everything from reviewing the guidelines and ensuring your app meets technical, design, and content requirements to going through the entire approval process. You can also count on our help to adapt the app to the new requirements if new regulations are announced.

Why choose Flutter for your development project?

Far better app performance

Thanks to its rendering engine and built-in widgets, Flutter apps run smoother and faster than most cross-platform solutions. This means that users can enjoy a native-like experience while you can save time and money by creating only one app that can run on multiple platforms. As Flutter's Dart code compiles directly to native ARM code, there's no need for a JavaScript bridge, significantly speeding up the rendering process. As a result, Flutter's performance often rivals native apps for Android and iOS.

A large number of built-in functions and libraries

Flutter has an impressive library of customizable widgets, making building apps for any device or platform a breeze. From adding smooth animations and interactive gestures to integrating Bluetooth and platform-specific features, there's a widget for almost everything. These pre-built tools save time, letting Flutter developers focus more on creating a great user experience and less on writing repetitive code. The wide range of libraries also makes it easy to connect to APIs, handle data storage, or add complex features like payment processing without starting from scratch.

Support for multiple platforms

Flutter isn't just made for mobile apps - you can also use it to create desktop and web apps. This means you can have one product that works seamlessly on different devices and platforms rather than building separate apps for each platform. Plus, the framework makes it easy to align the look, feel, and features of Android and iOS apps so they match perfectly while still respecting platform-specific guidelines.

Hot-reload makes adding changes or bug fixing easier

Hot-reload lets developers see changes in the app almost instantly, making the whole development process faster and more efficient. Instead of waiting to recompile or restart the app, you can watch updates happen in real time. This saves plenty of time, especially when fixing bugs, implementing new functionality, or tweaking designs, because you can test and adjust changes immediately.  As a result, the Flutter app development project takes less time, and the application is ready for launch faster.

Reduced maintenance and update costs

Reduced maintenance and update costs are a big win with Flutter. Since the same codebase works for multiple platforms, developers only need to maintain, update, or fix it once instead of separately for each version. This means less time and effort needed for maintenance tasks. Plus, Flutter's efficient architecture also makes debugging simpler, as developers can pinpoint and resolve issues without digging through tons of code in two or more applications, so the updates are ready much sooner.

Models of cooperation for Flutter application development services

Before your new Flutter mobile app project starts, it's worth having an expert look at the specifications first to ensure everything's set up correctly. We'll begin by talking with you a bit about the plans, goals, and challenges related to the new cross-platform app development project and then look through the plans you brought. Based on what we've learned, we'll then recommend the best technology, features, and strategies to shorten the development time and make the project more budget-friendly. You'll leave the meeting with a detailed project roadmap and all the information you might need to decide whether you want to work together with us on the project or not.
The more complex the project, the higher the risk that things might go awry at some point. If you're already in the middle of a project but run into unexpected technical problems, our development agency knowledge and skills will surely be useful. Whether you are struggling with a technical issue (like a new feature that causes the app to crash) or your team has problems meeting the deadlines, we can help you get to the bottom of the problem and find a way to fix it. If you need, you can also "hire" Flutter app developers from our company to work with your main team, for example, to help the web development team adjust the designs.
If you don't have the time or skills in-house to handle the mobile development project requirements yourself, we can step in, build a dedicated Flutter team, and manage the project for you. We'll start with a kick-off meeting and a series of workshops to brainstorm ideas for the project and then map out the development plan in detail. After that, we'll first create an MVP or prototype version of the app and, once we have your approval, move to the proper development stages, testing, and launch. Rest assured, our Flutter app development agency will take care of everything so you can focus on running your business.
Not every project goes according to the plan, we know - sometimes you just have to start over or ask another software development team or agency to help you with the project that had been left behind. The good news is we've got a lot of experience taking abandoned progress projects and getting them back on track. After we analyze the project requirements and the parts that have already been done, we will develop an actionable plan to update, restart, and then successfully finish the project.
Once the project is complete, we can hand over the entire project documentation to your team so they can manage it from now on. However, we can also stay with you for the long term and take care of maintenance and troubleshooting for you. Routine maintenance, security checks, updates and performance optimizations - you can leave all of those tasks to us and we’ll make sure the application runs smoothly on all devices and platforms.  

Launching an app is just the beginning. Keep your Flutter app running smoothly with our Flutter app maintenance and support services, for long-term performance and reliability.

Our Flutter application development process

01.

Quick consultation

The first meeting with our Flutter development agency will be all about getting to know your project and understanding its goals. We'll chat about what you hope to achieve, the features you need, and any challenges you might face. Together, we'll outline a rough plan that covers the development process, budget, and timeline. After this, you'll receive a detailed roadmap that breaks the iOS and Android app development process down step by step. This gives you a clear picture of what working with us would look like and helps you decide if our flutter development company is the right fit for your project.

02.

Kick-off & workshops

During the kick-off and workshops, we'll work closely with you to dig deeper into your vision, define key features, and map out the user journey. These sessions are hands-on and collaborative, giving us a chance to brainstorm ideas on how we should tackle the product development process and solve any tricky parts together. The result is a solid foundation for the new application, with a detailed plan, clear priorities and a shared understanding of what we're building.

03.

UX/UI design

UX/UI design is where the new app will get its personality and style. First, our Flutter experts will plan a layout that fits your brand perfectly, is easy to navigate, and looks great on all platforms you plan to launch. Our goal is to design an experience that feels natural for the users, keeping them engaged and coming back for more. You'll also get to see and test visual mockups and then give us our opinion on it - if something feels amiss, we'll then tailor the designs so they look exactly like you wanted.

04.

Prototyping stage

Next up is the MVP/Prototype stage, where we'll refine your project ideas and vision. We'll focus on creating a simple app with basic features first and then give you the test version to try it in and out. This lets you see how everything looks and feels while giving you a chance to gather feedback from users or stakeholders early on. Plus, adding, removing, or tweaking project elements at this point is pretty easy, so we can adjust the first model until you are sure that's how you want the Flutter app to look and work.

05.

Coding and implementation stage

Once we get thumbs up on the prototype or MVP version of your new cross-platform mobile app, we'll proceed to the coding and implementation stage. Our developers will write clean, efficient code for every part of the application to ensure it is fast, responsive, and ready to run across all platforms. We'll also keep you updated throughout the entire Flutter app development process so you'll always know how things are progressing.

06.

Testing stage

Before the app goes live, we'll test it thoroughly to make sure every element inside it works exactly how it should. Our team carefully checks every feature, button, and screen to catch bugs or glitches and fix them before the app is launched.  To make sure it looks and feels great on all devices and operating systems, we'll also test it on a variety of devices and in different conditions. This process also helps us improve performance, ensuring the app runs smoothly no matter how many people are using it or what device they are using. Once the app passes all our tests, it's ready to meet the users.

07.

Ongoing support and maintenance services

If you need, we can stay around even after the launch and keep your dedicated Flutter app running smoothly. For example, you can hire Flutter developers from our team to handle bugs, fine-tune performance, and stay on top of regular security checks so the app is always safe and dependable. If you want to roll out new features or updates, we can lend a hand with those, too, ensuring they fit seamlessly into the existing product. Our goal is to keep it reliable, user-friendly, and ready to grow as your needs evolve.
