Flutter app migration services

Turn your existing app into a flexible, high-performing Flutter application.

What can you gain from using our app migration services?

Single codebase working on multiple platforms

Managing separate codebases for iOS, Android, and web apps can be a hassle, right? Flutter changes the game by letting you write one codebase that works beautifully on all platforms. This means less time spent on updates, fewer bugs to fix, and more consistent design and performance for the users. Instead, you can focus on planning new features, designs, or any other enhancements that will delight the Flutter applications users. Plus, those can be implemented into all app versions at once, instead of having to estimate the development time and cost of adding those features separately.

Reduced development costs

While we're talking about money—Flutter is a smart choice for keeping costs under control. Instead of hiring separate developer teams to manage iOS, Android, and web apps, you only need one team to work on a single codebase. That alone can save you a significant chunk of your budget. On top of that, with Flutter's single codebase, maintenance and updates cost far less as well. Over the long term, those savings add up, leaving you with more resources to invest in new features, marketing, or scaling the application to handle more users.

Improved performance

Instead of relying on native components and bridges like other frameworks, Flutter uses its own high-performance rendering engine (called Skia) to draw everything directly onto the screen, skipping the extra steps other frameworks need. This means the app can react faster to user input and handles complex animations without the slightest issues, even during peak traffic times. In fact, Flutter's app performance often comes very close to the performance of native apps for both Android and iOS.

Consistent user experience

Have you ever noticed how some cross-platform applications feel entirely different on Android and iOS? That doesn’t exactly make for a great user experience for users who switch between devices and expect a consistent experience on both of them. Flutter fixes this by using its own widgets, which look and behave the same no matter the platform. Your product will feel polished and unified, whether someone's using it on a phone, tablet, or the web.

Easier maintenance, upgrades, and better scalability

Flutter simplifies maintenance and upgrades because there's just one codebase to manage instead of juggling separate ones for Android, iOS, and the Web. When bugs pop up, developers can make changes to the codebase and then roll out the updates to all platforms simultaneously. The same feature makes adding new features, tweaking design or adding any other enhancements much faster as well. Plus, Flutter's hot reload feature allows developers to test all changes right away, so they can test and deploy new updates in a much shorter time.  

Smooth and efficient migrating to Flutter

Planning migration to Flutter feels like it might be a long and complicated process. With our Flutter developer's experience, the process can be smooth, secure, and stress-free though. We'll make sure the app's data, functionality, and design are all moved to Flutter, optimized, and tested to work just as well (or better) as in the original application. After we finish the project, you'll get a cross-platform application that's fast, compatible and ready for launch.


After the migration, our team can also make sure your newly migrated Flutter app performs great for years to come - learn more about our performance optimization services.

Our Flutter app migration process

01.

First meeting

The first step is a simple conversation, during which we'll sit down with you to understand your main migration needs, goals, and any concerns about the migration process. This is your chance to tell us what matters most for the app and what you're hoping to achieve by using the Flutter framework. From there, we'll create a clear roadmap for the project, outlining how the migration will work and what the steps look like. After the meeting, you'll have all the information you need to decide if partnering with us is the right fit. Think of it as a no-pressure way to plan for success.

02.

Migration roadmap

Once we've had our first meeting, the next step is building a detailed migration roadmap. This is like the Flutter development project's game plan—it outlines every stage of the migration process, from start to finish, all adjusted to your specific needs. We'll also map out the timeline, key milestones, and any potential challenges so nothing catches you off guard. This roadmap helps you see exactly how the migration will look like and gives you a clear picture of the results you can expect from it. We'll also make sure there's plenty of room for feedback, so the plan fits your goals perfectly.

03.

UI and UX recreation

A big part of a migration is making sure the app looks and feels familiar but fresher and more polished. For this task, we'll map out the user interface and UX designs and then recreate them in Flutter, keeping all the elements your users love while improving any areas that could be better. This process ensures that the app not only works seamlessly on all platforms but also delivers a consistent experience for your audience. If there's room for enhancements—like smoother animations or a more responsive design—we'll suggest those too. Your iOS and Android users will get the experience they expect, with a little extra wow factor from us.

04.

Backend integration

Making sure your app's front end and back end work perfectly together is another crucial step in the migration process. We'll connect the Flutter app to the existing backend systems so everything runs smoothly without disrupting your current operations. This includes setting up APIs, syncing databases, and ensuring data flows reliably between the app and servers. If adjustments are needed to improve performance or compatibility, we'll handle those, too. Your users won't even notice the switch—they'll just enjoy how well everything works.

05.

Native functionality implementation

If your app uses special features like GPS, camera access, or push notifications, those need to work perfectly in Flutter, too. With the vast library of Flutter widgets, though, building a native-like, feature-rich mobile application is much easier than you might think. We'll pick the widgets for the new Flutter mobile app that will fit your needs the most, and then our developers will implement those, ensuring they're fast, reliable, and easy to use. Any performance tweaks or updates needed along the way will be taken care of. The goal is to keep everything working just as before—or even better.

06.

Testing

Before the migrated app goes live, we thoroughly test it to make sure everything works perfectly. This means checking every feature, fixing any bugs, and making sure the app performs smoothly on all devices. We also test how well it handles real-world scenarios, like heavy traffic or slow internet connections. Our team will make sure the app feels reliable and polished, just like your users expect. If anything isn't quite right, we'll catch it and make the necessary adjustments straight away, thanks to the hot reload feature.

07.

Post-launch support and maintenance

Getting the app live is just the beginning. Once it's out in the world, we can help you to keep things running smoothly as well. Regular maintenance, bug fixes, and updates are all part of the service, so the application stays up-to-date and problem-free. We’ll also monitor performance and handle any issues that come up, giving you peace of mind. If you want to add new features or make improvements down the line, our Flutter app development services can help with that, too.
