Flutter: Google’s Mobile UI Framework

Flutter: Google’s Mobile UI Framework

In the world of mobile application development where there are millions of Android or iOS Apps available in stores, UI is something which could make a difference. Flutter is Google’s mobile UI framework for crafting high-quality native interfaces on iOS and Android in record time that could simplify your life. It works with existing code, is used by developers and organisations around the world, and is free and open source.

What is Flutter SDK?

Flutter is an open-source mobile application development SDK created by Google. It is used to develop mobile applications for Android and iOS, as well as being the primary method of creating applications for Google Fuchsia.

How Flutter works?

In Flutter almost everything is a widget. It uses widgets are built using a modern react-style framework. The central idea is that you build your UI out of widgets. Widgets describe what their view should look like given their current configuration and state. When a widget’s state changes, the widget rebuilds its description, which the framework diffs against the previous description in order to determine the minimal changes needed in the underlying render tree to transition from one state to the next. It uses Dart as the programming language to create apps.


Why should you move to Flutter?

In one word I could say, if you want to ease your life in developing mobile UI’s or prototyping Apps in no time then you should give it a try. Below are some of the key highlights:

Fast Development

Flutter’s hot reload is one of the feature you will make you fall in love with this emerging framework. The hot reload helps you quickly and easily experiment, build UIs, add features, and fix bugs faster. Experience sub-second reload times, without losing state, on emulators, simulators, and hardware for iOS and Android.

Expressive and Flexible UI

You could build beautiful looking apps with Flutter’s built-in beautiful Material Design and Cupertino (iOS-flavor) widgets, rich motion APIs, smooth natural scrolling, and platform awareness. Layered architecture allows full customisation, which results in incredibly fast rendering and expressive and flexible designs..

Native Performance

Flutter’s widgets incorporate all critical platform differences such as scrolling, navigation, icons and fonts to provide full native performance on both iOS and Android.

Modern, reactive framework

Easily compose your UI with Flutter’s modern reactive framework and rich set of platform, layout, and foundation widgets. Solve your tough UI challenges with powerful and flexible APIs for 2D, animation, gestures, effects, and more.

Access native features and SDKs

Make your app come to life with platform APIs, 3rd party SDKs, and native code. Flutter lets you reuse your existing Java, Swift, and ObjC code, and access native features and SDKs on iOS and Android.Accessing platform features is easy.

Unified app development

Flutter has the tools and libraries to help you easily bring your ideas to life on iOS and Android. If you don’t have any mobile development experience, it is an easy and fast way to build beautiful mobile apps. If you are an experienced iOS or Android developer, you can use it for your views and leverage much of your existing Java/Kotlin/ObjC/Swift investment.


There is a decent support with great documentation library on the official website which is detailed enough to begin with. Also there is a fast growing developer community support available on Github.


Flutter’s release preview 1 has been announced signalling a new phase of development as it moves into the final stages of stabilisation for 1.0. You can download and install the Flutter SDK from the official website.
