Build beautiful, natively compiled applications for mobile, web, and desktop from a single codebase.\u00a0<\/span><\/p><\/blockquote>\n

With mobile applications continuing to become more and more popular with each passing day, many programming tools are readily available to developers who want to create them. Among these tools, lately, Flutter has distinguished<\/strong> itself!<\/span><\/p>\n

What is Flutter?<\/span><\/h2>\n

Flutter\u00a0is an\u00a0open-source\u00a0UI\u00a0software development<\/strong> kit\u00a0created by\u00a0Google<\/a>. It is used to develop applications for Android. iOS, Mac, Linus, Google Fuchsia, Windows, and the web from a single codebase. <\/sup><\/span>It is not just a framework, but a complete software development kit<\/strong> (SDK), which contains everything one needs to build cross-platform applications. This includes a rendering engine, ready-made widgets, testing and integration APIs, and command-line tools.<\/p>\n

Framework Architecture Of Flutter<\/span><\/h2>\n

There are four major components of Flutter:<\/span><\/p>\n

Dart Platform<\/span><\/h3>\n

Dart<\/strong><\/a><\/span> is Flutter\u2019s object-oriented language that uses Ahead-of-Time<\/strong> compilation techniques and compiles into native code without that additional bridge. This helps speed up the app startup time.<\/span><\/p>\n

Moreover, Flutter doesn\u2019t have to call OEM (original equipment manufacturer)<\/strong> widgets, because it uses its own. It uses the OS as a canvas to build an interface on and moves services such as gestures, rendering, and animations into the framework itself, which gives developers complete control over the system.<\/sup><\/span><\/p>\n

Flutter Engine<\/span><\/span><\/h3>\n

Flutter’s engine, which is primarily written in C++<\/strong>, provides low-level rendering support using Google’s Skia<\/a><\/span> graphics library. It also interfaces<\/span> with platform-specific\u00a0SDKs\u00a0such as those provided by\u00a0Android\u00a0and\u00a0iOS. <\/span><\/p>\n

<\/sup>The Flutter Engine is a portable runtime for hosting Flutter applications. It implements Flutter’s core libraries, including animation and graphics, file and network I\/O, accessibility support, plugin architecture, <\/strong>etc. Most developers interact with Flutter via its framework because this renders a reactive framework and a set of platform, layout, and foundation widgets.<\/span><\/p>\n

Foundation Library<\/span><\/h3>\n

The Foundation library, which is written in Dart, provides basic classes and functions. These can be used to construct applications (APIs) <\/a><\/span>using Flutter to communicate with the engine.<\/span><\/sup><\/sup><\/p>\n

Design-specific Widgets<\/span><\/h3>\n

The Flutter framework contains two sets of\u00a0widgets.<\/a> They conform to specific two design languages:<\/span><\/p>\n

    \n
  1. Material Design<\/a> <\/strong><\/span>widgets, which implement Google’s design language of the same name<\/span><\/li>\n
  2. Cupertino\u00a0<\/strong>widgets, which implement Apple’s iOS human interface guidelines<\/a>.<\/span><\/span><\/sup><\/li>\n<\/ol>\n
