Can you explain what is meant by primitive data types in programming?

Primitive data types are basic types that store simple values and do not have internal structure or methods. In the Dart language (used in Flutter), primitive types include, for example, int (integers), double (floating-point numbers), bool (logical type — true/false), and String (strings, although in some languages strings are considered objects).

Primitives are usually stored directly in memory and passed by value, which differs from reference types that store references to objects.

Example:

int age = 30;
bool isActive = true;
double price = 19.99;
String name = 'Alice';
