Flutter by Google: Introduction, Features and App Examples

Today, cross-platform development toolkits are taking over the developers’ community.

The benefits like reusable blocks of UI, code usability on multiple platforms, and reactive performance are making them gain ground for cross-platform app development frameworks. And, one such incredible framework for mobile app development is ‘Flutter’ by Google.

What is Flutter?

Google introduced Flutter in 2017 as an open-source, cross-platform mobile application development framework for developing native apps on Android and iOS which would aid wrapping up of a web-view in a native app.

The positive response towards this framework prompted Google to take one step ahead and announce the further version- Flutter 1.0 too.

This version is called as the initial stable launch of Google’s UI toolkit, which would help in developing attractive native UX for cross-platform mobile apps which uses a single codebase.

Google also revealed several third-party integrations and previewed some of the forthcoming features. Flutter was introduced in May 2017 as an alpha version before the first beta version arrived in February. The beta 3 was next, followed by a couple of release previews.

With the development of Flutter 1.0, Google wanted to compete with React Native of Facebook with library combining the optimum performance and integration of the platform including native mobile with faster development.

With Flutter, Google also aims to resolve the problems related to cross-platform app development. It is expected to offer outstanding graphics and User Interface along with a robust native ARM code for both platforms- Android and iOS development.

Features of Flutter Framework:

  1.  Fast Development with Hot Reloading:

With it’s Hot Reload’ feature, developers can preview code changes in the simulators, emulator or hardware for any platform i.e. Android or iOS that too without re-building the app. This helps developers to experiment with the code, add features, build UIs and fix bugs even faster.

  1. Built-In Widgets:

Flutter facilitates the app development with a number of independent and reusable blocks of UI, which are later used to develop a comprehensive/complex UI.

It also offers Cupertino (iOS-flavor), Material Design and widgets to build these User Interface blocks, along with supple APIs for 2D animation, effects, gestures and much more.  

  1. No Reliance on Original Equipment Manufacturer (OEM):

What makes Flutter so different than any other mobile app development framework is that it neither uses web-view nor OEM widgets that come with the device.

It instead uses its own high-performance widgets.

  1. Uses Dart Language for App Development:

The User Interfaces (UIs) in Flutter are built with Dart language, a modern, concise, object-oriented language. Dart uses a C-style syntax that optionally trans-compiles into JavaScript.

Since the day Flutter is introduced, it is helping the developers to build cross-platform native apps with no compromise and it has been entrusted by startups and established brands too for app development.

Here, we are mentioning 10 apps that are built with Flutter!
