What is Flutter Software?
Flutter is popularly known as an open-source User Interface software development kit. It was created by Google and is used to develop various applications for different operating systems such as Android, iOS, Windows, Mac, Linux, and the web.
Achieving 120 frames per second speed on a mobile device is practically hard. However, Flutter makes is unbelievably easy and smooth. Applications that are built with Flutter have a great native performance on both Android and iOS without the JavaScript bridge. Inserting a widget or a button is a pretty easy and simple process if you are using Flutter.
Different versions of Flutter
The very first version of Flutter was codenamed “Sky”. It ran on an Android OS. However, it was later unveiled at the Dart developer summit in 2015. It had the intention of being able to render consistently at 120 frames per second.
When they were unveiling this, Google announced that Flutter Release Preview 2 would be the last big release before Flutter 1.0. In 2018, Flutter 1.0 was released at the Flutter Live event, which denoted the very first stable version of the Framework. Later on, in 2019, Flutter 1.12 was released at the Flutter Interactive event.
Framework Architecture
Dart platform
All the Flutter apps are usually written in Dart language which is Google’s OOP platform. They make use of advanced features by using DART. It was available on Windows, Mac, and Linux via the semi-official Flutter Desktop Embedding project. It should be noted that Flutter runs on the Dart virtual machine which features an as-and-when execution engine. On writing and debugging an app, Flutter uses just-in-time compilation, that allows for it to hot reload with modifications to its source files that can be injected into a running application.
The released versions of Flutter apps are compiled with futuristic compilation on both Android and iOS, which makes Flutter’s high performance on mobile devices possible.
Flutter engine
The engine of Flutter is written primarily in C++ language which provides low-level render support by using Google’s Skia graphics library. Additionally, the interface connected with platform-specific SDKs such as those provided by Android and iOS. Flutter’s Engine is a portable runtime for hosting specifically Flutter applications. It also implements Flutter’s core libraries, including animation and graphics, plugin architecture, and a Dart runtime. Most developers likely interact with Flutter via the Flutter Framework, which provides a modern and yet reactive framework.
Foundation library
The Foundation library that is written in what is called – Dart. It provides very basic classes and functions which are used to construct various applications using Flutter, such as APIs to communicate with the engine.
Widgets
The design of UI in Flutter involves using composition to create widgets from the other widgets. Here, the trick is to understand this and realize that any tree of components (Widgets) that is assembled under a single build method can also be referred to as a single Widget. This is because of those smaller Widgets that are also made up of even smaller Widgets, and each one has its build method of its own. That is how Flutter makes use of the Composition.
Design-specific widgets
The framework of Flutter contains two sets of widgets that conform to the specific design languages. The material Design widgets can implement the popularly used Google’s design language by the same name, and Cupertino widgets that implement Apple’s human interface Guidelines by using iOS design.
