Variables are an essential part of any programming language, including Dart. They store and manipulate data efficiently. Dart provides a variety of data types to handle different types of values, ensuring flexibility and ease of development. In this guide, we will explore variables, data types, and naming conventions in Dart.
A variable in Dart is a named storage location that holds a value. The value stored in a variable can be changed during the program execution. Variables help in data manipulation, making the code dynamic and interactive.
Declaring Variables in Dart
In Dart, variables can be declared using the var, final, const, or explicit data type keywords.
var name = "Usama"; // Dart infers it as a String int age = 25; // Explicitly declaring an integer variable final String country = "Pakistan"; // Immutable variable const double pi = 3.14159; // Compile-time constant
