Can you list the main primitive data types used in programming?

The main primitive data types in programming typically include:

• Integers (int) — for storing whole numbers.
• Floating-point numbers (float, double) — for storing fractional numbers.
• Boolean values (bool) — take values true or false.
• Characters (char) — individual symbols, such as letters or digits.
• Strings (string) — sequences of characters (considered primitive in some languages, objects in others).

In Dart language (used in Flutter), the main primitives are:

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