What is Flutter

What is Flutter?

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

Flutter is  high-fidelity mobile apps for iOS and Android. You'll feel powerful and productive with Flutter's functional-reactive framework and our extremely fast hot reloads on devices and emulators. You'll write your Flutter apps in Dart. 
Flutter apps are written in the Dart language and make use of many of the language's more advanced features.

Like React Native, Flutter also provides reactive-style views. Flutter takes a different approach to avoiding performance problems caused by the need for a JavaScript bridge by using a compiled programming language, namely dart. Dart is compiled “ahead of time” (AOT) into native code for multiple platforms. This allows Flutter to communicate with the platform without going through a JavaScript bridge that does a context switch. Compiling to native code also improves app startup times.

1. h-quality native interfaces” : Flutter contains elements from both Android and iOS, but unlike React Native, all elements, or “widgets”, are usable on both platforms. An app can now look exactly the same on both platforms instead of adopting platform specific looks.
2. “iOS and Android in record time” : The same codebase is usable for both Android and iOS apps reducing the need for separate development for Android and iOS. “But couldn’t we do the same in React Native?” Yes, but because RN pulls interface elements from the device, a lot of elements were platform specfic, rendering a single codebase to be larger than it needs it be

Why Flutter?

What are some advantages of Flutter? It helps you:

• Be highly productive
  • Develop for iOS and Android from a single codebase
  • Do more with less code, even on a single OS, with a modern, expressive language and a declarative approach
  • Prototype and iterate easily
    • Experiment by changing code and reloading as your app runs (with hot reload)
    • Fix crashes and continue debugging from where the app left off
• Create beautiful, highly-customized user experiences
• Benefit from a rich set of Material Design and Cupertino (iOS-flavor) widgets built using Flutter’s own framework
• Realize custom, beautiful, brand-driven designs, without the limitations of OEM widget sets

Core Principle   

Flutter includes a modern react-style framework, a 2D rendering engine, ready-made widgets, and development tools. These components work together to help you design, build, test, and debug apps. Everything is organized around a few core principles.
