Dart Data Types
Dart Data Types
Dart data types include int String and bool with type inference.
Introduction to Dart Data Types
Dart is a statically typed language, which means that every variable must have a type. The Dart language provides several built-in types that you can use to declare variables. Understanding these types is crucial for effective programming in Dart.
Integer (int)
The int type is used to represent whole numbers. It can be both positive and negative, and there's no need to specify the size, as Dart handles it efficiently.
String
The String type represents a sequence of characters. Strings are immutable in Dart, meaning once a string is created, it cannot be changed.
Boolean (bool)
The bool type represents a Boolean value, which can be either true or false. This type is commonly used in control flow statements.
Type Inference
Dart supports type inference, which allows you to declare variables without explicitly specifying their type. The Dart compiler infers the type from the context.
Conclusion
Dart's type system is robust and supports both explicit typing and type inference, making it flexible for developers. Understanding and using Dart data types effectively is a foundational skill for any Dart programmer.
