Dart Features

In this tutorial you will learn about the Dart Features and its application with practical example.

Dart Features

The Dart is an open source, object oriented programming language. The Dart provides lots of convenient features mainly focused on compilation, execution, safety, memory management, and concurrency. Below is a list of some of important features among Dart’s features are –

Table Of Contents

Object Oriented Programming :- Dart is an object-oriented programming language with support for inheritance, interfaces and optional typing features. It also supports interfaces, mixins, abstract classes, reified generics, static typing, and a strong type system.

Open Source :- Dart is an open source programming language and it comes with a set of tools for compiling and executing Dart Code. It is recognized as an ECMA standard and is available with a BSD licence.

Cross-Platform :- Dart is cross-platform and supports all major operating systems. The Dart compiler come with its own Virtual Machine which allows Dart programs to run on every systems.

Browser Support :- The Dart code can be trans-compiled into JavaScript using source-to-source compilation. There is a dar2js compiler which transpile Dart code into optimized JavaScript code that runs on all modern web browsers.

Type Safe :- The Dart is type safe programming language. Dart uses a combination of static type checking and runtime checks to ensure that a variable’s value always matches the variable’s static type. Although Dart is strongly typed, type annotations are optional because of type inference.

Ahead-Of-Time (AOT) :- Dart supports Ahead-Of-Time (AOT) compilation mode. In this mode, the Dart code can be directly converted into native machine code. Apps built with Flutter are deployed to app stores as AOT Compiled Dart code.

Reuse Of Code :- Dart cade can be compiled optimized JavaScript code that can be executed on all modern web browsers. This allows Dart code reuse between mobile apps and web apps. It is being reported that Dart code can be reused as high as 70% code between their mobile and web apps.

Flexible Compilation and Execution :- Dart is unusually flexible at compilation and execution. Dart code can be efficiently compiled AOT or JIT, interpreted, or transpiled into other languages. Not only is Dart compilation and execution unusually flexible, it is especially fast.

Asynchronous Programming :- Dart supports asynchronous programming which let your program run without getting blocked. Dart is a single threaded programming language that helps the developer ensure that critical functions to be executed till completion, without preemption.

Concurrency :- Dart is an asynchronous programming language. Dart uses isolates in order to achieve concurrency. Isolates are independent workers that do not share memory, but instead communicate by passing messages over channels, isolates are similar to actors in Erlang or web workers in JavaScript. Since isolates are communicating via passing messages thus it needs a way to serialize a message. This is done using a snapshot, which is generated from a given object, and then this is transferred to another isolate for deserializing.

Strong Tooling :- Dart SDK ships with an extensive set of execution environments, libraries and tools that are designed exclusively for the language.

The Dart project also ships an editor. You’ll find code completion, refactoring, quick fixes, code navigation, debugging, and more. Also, IntelliJ has a Dart plugin.

Libraries :- Dart comes with a rich set of inbuilt libraries installed in the Dart SDK including core, async, math, convert etc. Dart allows you to organize Dart code into libraries, for easier namespacing and reusability. Later you can import a library, and libraries can re-export.

Familiar Syntax :- As far as concern to language syntax, Dart doesn’t reinvent the wheel. if you look at Dart code you will find its syntax is quite similar to Java and C#.

Community :- Dart is backed with a large community of Dart developers. So it is easy to find help if you stuck at some point while developing an application.

In this tutorial we have learn about the Dart Features and its application with practical example. I hope you will like this tutorial.
