Why Flutter for mobile and web app development?

In general, developing a mobile application is a complex and challenging task. There are many frameworks available to develop a mobile application. Android provides a native framework based on Java language and iOS provides a native framework based on Objective-C / Shift language. However, to develop an application supporting both OSs, we need to code in two different languages using two different frameworks. To help overcome this complexity, there exist mobile frameworks supporting both OS. These frameworks range from simple HTML based hybrid mobile application framework (which uses HTML for User Interface and JavaScript for application logic) to complex language-specific framework (which do the heavy lifting of converting code to native code). Irrespective of their simplicity or complexity, these frameworks always have many disadvantages, one of the main drawbacks being their slow performance. In this scenario, Flutter — a simple and high-performance framework based on Dart language, provides high performance by rendering the UI directly in the operating system’s canvas rather than through the native framework. Flutter also offers many ready to use widgets (UI) to create a modern application. These widgets are optimized for mobile environments and designing the application using widgets is as simple as designing HTML. To be specific, the Flutter application is itself a widget. Flutter widgets also support animations and gestures. The application logic is based on reactive programming. The widget may optionally have a state. By changing the state of the widget, Flutter will automatically (reactive programming) compare the widget’s state (old and new) and render the widget with only the necessary changes instead of re-rendering the whole widget.
