Dart Programming Language
What is Dart?
Google created Dart, a high-level, general-purpose programming language, in the beginning. Although it was first introduced as a new programming language in 2011, its stable version wasn’t made available until June 2017. When the Flutter uses dart, it becomes more well-known even though it wasn’t very popular at the time.
Dart is an object-oriented, dynamic, class-based programming language featuring lexical and closure scope. It shares a lot of syntactic similarities with Java, C, and JavaScript. You can pick up Dart programming language quickly if you are familiar with any of these programming languages.
Developed with the Flutter framework, Dart is an open-source programming language that is extensively used to create modern web applications, desktop applications, and Internet of Things (IoT) applications. A few advanced ideas like mixins, abstract classes, refield generics, interfaces, and type interfaces are also supported. It is a compiled language that works with two different kinds of compilation methods.
- AOT (Ahead of Time) – It operates on all current web browsers and uses the dar2js compiler to turn Dart code into efficient JavaScript code. At build time, the code is compiled.
- JOT (Just-In-Time): It translates machine code (native code) from byte code, but only the necessary code.
History
The first public unveiling of Dart took place during the GOTO conference in Aarhus, Denmark, from October 10–12. At first, Lars Bark and Kespar conceived it, and Google developed it.
On November 14, 2013, Dart’s initial version 1.0 was made available with the goal of replacing JavaScript.
At its 107th General Assembly in July 2014, Ecma International authorized the first edition of the Dart language.
A web problem in the initial version drew criticism, and with the introduction of Dart 1.9 in 2015, this concept was abandoned.
In August, Dart 2.0 was updated to version 2.0, which featured a sound type system.
The extension method is an addition to the latest version of Dart 2.7 that allows us to add any kind of functionality.
Why Dart?
In the next section, we define the features of Dart.
- Because it is platform-independent, Dart can be used with any operating system, including Windows, Mac, Linux, and others.
- Since it is an open-source language, anyone can use it for free. It is compliant with the ECMA standard and has a BSD license.
- Programming in the object-oriented style, it supports all the characteristics of oops, including interfaces, inheritance, and optional type features.
- Because of its reliability, Dart is highly helpful when developing real-time apps.
- The dar2js compiler, included with Dart, translates Dart code into JavaScript code that is compatible with all current web browsers.
- Dart code may execute in a command-line interface environment thanks to the standalone Dart virtual machine.
Key Points to Remember
These are the things we should consider before learning how to play the dart. These ideas are listed below.
- Like Python, everything in Dart is regarded as an object, including functions, Boolean logic, and numbers. Every object derives from the class Object.
- Errors and warnings are the two categories of issues that Dart tools might report when developing. While errors might stop code from running, warnings are a sign that your code might have issues; they don’t stop the code from running.
- Sound typing is supported by Dart. This is something that the upcoming tutorial will cover.
- Generic types, such as List<int> (a list of integers) and List<dynamic> (a list of objects of any type), are supported by Dart.
Prerequisite
Even complete beginners can learn the Dart programming language without any prior expertise. Dart’s syntax is comparable to those of Java, C#, Java, JavaScript, and so on. Knowing any of these programming languages will make learning easier and quicker.
Audience
This lesson is designed for both novices and experts who wish to understand the fundamentals of Flutter or pursue a career in web development. Numerous topics are offered to make learning the dart programming language simple.
