Why flutter is the best solution for your mobile app
Far better app performance
With its own rendering engine and widgets that are part of the framework, Flutter's apps perform much better than typical cross-platform applications. For example, on newer iOS devices, Flutter can improve rendering performance by up to 50% and reduce memory consumption by up to 70%.
A large number of built-in functions and libraries
Flutter has a large number of customizable widgets that make it easy to create applications for any device or platform. Whether you want to add gestures, animations, Bluetooth, or IoS-dedicated features, you can find a Flutter widget to help you add those to your app.
Support for multiple platforms
Flutter can be used to create mobile apps but also desktop, web, or embedded apps. What’s more, the Flutter framework lets you align Android and iOS interface style, features, and logic so that way, you can design apps that look and work consistently across different platforms.
Hot-reload makes adding changes or bug fixing easier
Hot-reload allows you to instantly check how the app performs after adding modifications. After adding the changes, Flutter updates the code while the application is still running, so you don't need to recompile or restart the application to see the result. This is not just useful for designing UIs or adding new features, but also for bug fixing.

Consulting before your Flutter project starts
Discuss your idea with an expert before committing your time, energy, and resources to the project. You can count on us here. After analyzing your project requirements, we can advise you on which mobile app or web app technology would be the best fit for your new app, how to design the UX/UI, but also what parts of your project could be sped up.
Consulting an ongoing Flutter project
The more complex the project, the higher the risk that, at some point, things might go awry. If you're already in the middle of a project, but you ran into some unexpected problems, our team’s knowledge and skills will surely come in handy. Whether you are struggling with a technical issue (like a new feature that causes the app to crash, for example) 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.
Starting a Flutter app project from scratch
If you don’t have the time or skills in your in-house team to handle the mobile development project requirements yourself, we can step in and manage the project for you. We’ll start with a kick-off meeting and a series of workshops to make sure we are on the same page, and then we’ll be working closely with you during all mobile app development stages.
Taking over an existing project
Not every project goes according to the plan, we know - sometimes you just have to start over or ask another 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 your project requirements and the parts that have already been done, we will develop an action plan to regain control of the project's progress and then successfully finish it.
Post-launch support and maintenance
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. We'll take care of any problems that arise, and we'll ensure that your app runs smoothly at all times.

Flutter FAQ
What is Flutter?
Flutter is an open-source development framework made by Google through which you can create native-like applications using the same codebase. Flutter also comes with a set of widgets and tools that allow developers to create attractive and fast applications that support operating platform or device features, such as gestures.
Who is using Flutter?
Plenty of companies! For example, Groupon has been using Flutter to create and manage their merchant app. The framework is also used by companies such as Alibaba Group, Groupon, BMW, eBay, or Tencent.
Why should I pick Flutter for app development?
The main reason is that creating apps with Flutter is easier than creating native apps, while their features, performance, and customization options are nearly identical. The hot-reload feature can especially make building or updating an app smoother, as you can test how the app works without having to recompile the code and restart the app.
What are Flutter widgets?
Widgets are in-built Flutter framework elements you can use to build your app. The widgets are divided into 14 categories, such as accessibility, animation, icons, input functionality, styling, or widgets designed specifically for iOS development. In addition, widgets allow you to add features to your app that are not typically available in cross-platform apps, such as gestures.
Is Flutter the best choice for my project?
That depends. You might want to consider Flutter if you need to build an app for both iOS and Android simultaneously or want to make an MVP app first. However, if you aren’t sure will Flutter work for your project, the best option will be to ask a development agency for their opinion. Contact us through the online form adding a short description of your project, and we can arrange a quick.
