Dart Datatypes

In this tutorial, we will learn about Dart datatypes. Dart is a statically typed programming language, meaning every variable has a specific type associated.

Basic data types in Dart programming language are as follows:

Numbers

int: Represents integer values, such as 9, 15, -7, etc.

double: Represents floating-point values with decimal places, such as 3.14, -0.79, etc.

Strings

String: Represents a sequence of characters, enclosed in single or double quotes, such as “Hello”, ‘TestingDocs’, etc.

Boolean

bool: Represents a boolean value, which can be either true or false.

Lists

List: Represents an ordered collection of objects. Lists in Dart can contain objects of any type.

Map

Map: Represents a collection of key-value pairs. Maps in Dart can have keys and values of any type.

Set

Set: Represents an unordered collection of unique objects. Sets in Dart can contain objects of any type.

Runes

Runes: Represents a sequence of Unicode characters. Runes are used to represent special characters or emoji.

Symbol

Symbol: Represents an identifier that is used internally by Dart to represent operators, declarations, etc.

Additionally, Dart programing language provides support for defining custom classes, enums, and type annotations to create more complex data structures.
