Flutter is Google’s UI toolkit for crafting interactive, natively compiled applications for mobile, web, and desktop from a single codebase. On December 11, 2019, Flutter 1.12 was released at the Flutter Interactive event. Google announced that Flutter was the first UI platform designed for ambient computing. While it’s relatively new, more than one million developers are currently using Flutter.

Google flutter fits into the “ambient computing vision of Google,” which is to create applications that will operate on multiple platforms and devices with a single code base. Flutter is capable of to deploy applications over Web, Android, iOS, Desktop, and even Google’s fuchsia, which is a fusion of its Chrome and Android operating systems (OS). Flutter would be the first open-source platform that allows cross-platform development together in Android, iOS, web, embedded systems – with a single code base.

The unique feature that sets Flutter apart from the rest is, Flutter apps are written in Google’s Dart language, which can be compiled to JavaScript and can be executed by browsers. Dart allows code reuse between mobile apps and web apps. Dart is a modern, concise, object-oriented language that developers can easily approach read, change, replace, or remove. It can also be used on a server either by being compiled to native code or by compiling to JavaScript and using it with node.js.

Flutter is distinct because it only has a thin layer of C/C++ code, and it implements most of its operations (compositing, gestures, animation, framework, widgets, etc.) in Dart. This gives developers great control over the system and offers immense flexibility too. Finally, Dart also provides a standalone VM that uses the Dart language itself as its intermediate language (essentially acting as an interpreter).

Features of Flutter

Fast Performance

Flutter enables quick and dynamic mobile app development where the developers can change the code, and it reflects directly in the app. This is done using ‘Hot Reload.’ It works by injecting updated source code files into the running Dart Virtual Machine (VM). After the VM updates classes with the new versions of fields and functions, the Flutter framework automatically rebuilds the widget tree, allowing you to view the effects of your changes quickly.

Expressive and Flexible UI

Flutter can build highly attractive apps, and it focuses on native end-user experience. The layered architecture allows for full customization, and it lets you control every pixel on the screen. The powerful compositing capabilities enable you to overlay and animate graphics, video, text, and controls without limitation.

Flutter includes a full set of widgets that deliver pixel-perfect experiences on both iOS and Android. It offers the whole experience and usage of Material Design, Google’s open design system for digital experiences.

Native Performance

Widgets are the central class hierarchy in the Flutter framework. The widget support of Flutter provides a seamless user experience regardless of screen size. Widgets offer features like navigation, scrolling, icons, and fonts to provide full native performance on both iOS and Android.
