Can you name the main primitive data types used in Dart?

In Dart, the main primitive data types include:

• int — integers
• double — floating-point numbers
• bool — boolean values (true/false)
• String — text strings
• null — a special value indicating the absence of a value

Example usage:

int age = 30;
double price = 19.99;
bool isActive = true;
String name = "Dart";
