What is the difference between an anonymous function and a named function in programming?

A function without a name (anonymous function or lambda) is a function that has no name and is usually used for short-term operations, such as an argument to another function. A named function has a name and can be called from different parts of the code.

Example in Dart (Flutter):

// Named function
int add(int a, int b) {
  return a + b;
}

// Anonymous function
var multiply = (int a, int b) => a * b;

void main() {
  print(add(2, 3));       // 5
  print(multiply(2, 3));  // 6
}

Anonymous functions are convenient for passing logic into other functions, such as event handlers or collection methods.
