Top 6 pros of Flutter
From the perspective of an app owner, the crucial advantages are as follows: Flutter speeds up the mobile app development process, reduces the cost of app production, and helps your team to build a beautiful app UI with smooth animations. Let’s take a look at it more deeply.
1. Faster code writing
For developers, Flutter means faster & more dynamic mobile app development. We can make changes in the code and see them straight away in the app! This is the so-called Hot reload, which usually only takes (milli)seconds and helps teams add features, fix bugs, and experiment faster. It is one of the things about Flutter loved by every top Flutter app development team.
Hot reload is also very comfortable in developer-designer cooperation when we want to improve or experiment with an app’s look and check the effects on the spot. In other words, with Flutter, your designer or tester can work together with a developer on the UI, making changes – for example, “Put it 2 pixels right” or “Make the animation faster” – and see them immediately.
Most types of code changes can be hot reloaded. But there is a list of changes that require a full restart: Hot reload Limitations.
Whereas, in the case of native app development the project needs to be rebuilt and that takes much more time. You have to wait for every single change – sometimes, even up to several minutes.
2. One code for 2 platforms
Developers write just one codebase for your 2 apps – covering both Android and iOS platforms. Flutter doesn’t depend on the platform, because it has its own widgets and designs. This means that you have the same app on two platforms. Yet what’s important is that, if you want to differentiate your apps – it’s possible.
3. Less testing
If you have the same app for 2 platforms, it means less testing! The Quality Assurance process can be faster. Because of one codebase, the developers write automatic tests only once. What’s more, Quality Assurance specialists have less work to do, because they have only one app to check. Of course, if your apps have some differences, they need to be tested on both platforms.
4. Faster apps
Flutter apps work in a smooth and fast way, without hanging and cutting while scrolling. If you want to understand why and how it works from the technical point of view, read this article.

5. Designs which your users will love
Flutter is designed to make it easy to create your own widgets or customize the existing widgets. Here you can browse a catalog of Flutter’s widgets and view, for example, Material Design widgets and Cupertino widgets.
6. The same app UI on older devices
Your new app will look the same, even on old versions of Android and iOS systems. There are no additional costs for supporting older devices. Flutter runs on Android Jelly Bean or newer, as well as iOS 8 or newer.
