Cross-platform apps are a long-standing dream of any business because separate (native) apps for iOS and Android are significantly more expensive to develop and maintain.
In simple terms, a cross-platform is a set of tools (framework) that allows you to create software suitable for both iOS apps and Android apps. Sounds great at first glance. In fact, each framework has its own capabilities and limitations. There are a lot of them: React Native, Xamarin, PhoneGap, Titanium, Ionic, and Flutter - the most popular.
An ideal cross-platform app should meet two requirements:
- be economical in terms of development;
- provide a high-quality user experience.
Economy. The benefit isn't just making one app instead of two. It would also be nice to catch a minimum of problems when adapting to each of the platforms. This is all right for most frameworks when viewed in the context of simple applications.
Problems begin when the mobile app becomes overgrown with functions and inevitably becomes more complex (this is what any product at the development stage comes to).
User experience. It is important to perceive a cross-platform application as native - that is, as if it was written specifically for this platform. In making a successful Android or iOS app, there at least should be smooth animations, interface elements typical for this OS, and work with gestures. And this is bad for everyone except Flutter app development.
Oftentimes, a cross-platform app looks like a more advanced mobile version of a website wrapped in an app. Animations slow down, unusual interface elements with unpredictable behavior are used. If you wouldn’t want that with a web development project, then you surely wouldn’t want it with the development of an Android project.
All this worsens the user experience of the mobile application, as a result, lowers the ratings in the stores and retention rates (the rate of return of users to the application). In Flutter, there is no such problem, smooth animations are its advantage, you can use familiar and user-friendly native elements without any problems.
An Android developer should be familiar with the process of creating a smooth experience for any Android development project. One of the understated tips and tricks for Android, is to put user experience above all else. Your mobile app can have all the features in the world, but if the user experience is slow or frustrating, don’t expect anyone to regularly use your app.
