Dart Tutorial

Welcome to Dart Tutorial by TutorialKart.

In this series of Dart Tutorials, we learn the basic concepts of Dart programming language.

Pre-requisites to learn Dart

There are no specific pre-requisites to learn Dart programming language. Of course having an idea of programming concepts help you learn faster. These Dart Tutorials are designed to address the beginners who have no idea of programming.

If you know any of the programming languages like C#, Java, JavaScript, etc., learning Dart becomes relatively easy.

IDE for Dart Programming

You can use any text editor present in your PC to write Dart code. Or, you can also use Dart Editor.

Dart Editor is very light-weight and productive for developers.

You can also use Eclipse or IntelliJ IDE to develop Dart applications. They have rich Dart editing experience.

Dart is used in:

• Flutter (Mobile Application Development)

String Operations

These Dart Tutorials cover String Operations that are mostly required while working with Strings. It contains operations like adding two strings, splitting a string by a specific delimiter, replacing a substring with another in a string, computing substring of a string given start index and end index, calculating the length of a string, trimming a string with trailing and leading white space characters, etc.

Dart Collections

List, Set, Map and Queue are the collection classes implemented in Dart. In the following Dart Tutorials, we walk you through these Collection classes and different properties and operations that could be performed on them.

In Dart, List is a collection of elements that can belong to different types. Also, elements in list are indexed. We can perform different operations of List with the help of built-in properties and methods of List class or primitive conditional and Looping statements.

Lists

Sets

Dart Set is a collection of unique elements that can belong to different types.

Following series of Dart Tutorials go through most useful operations on Dart Sets.
