Dart is an actively used programming language created in 2011. Dart is a general-purpose programming language originally developed by Google and later approved as a standard by Ecma (ECMA-408). It is used to build web, server and mobile applications, and for Internet of Things (IoT) devices. It is open-source software under a permissive free software license (modified BSD license).

Example code from the Hello World Collection:

// Hello world in Dart

main() {
   print('Hello world!');
}

Example code from Linguist:

import 'dart:math' as math;

class Point {
  num x, y;

  Point(this.x, this.y);

  num distanceTo(Point other) {
    var dx = x - other.x;
    var dy = y - other.y;
    return math.sqrt(dx * dx + dy * dy);
  }
}

void main() {
  var p = new Point(2, 3);
  var q = new Point(3, 4);
  print('distance from p to q = ${p.distanceTo(q)}');
}

Example code from Wikipedia:

// Import the math library to get access to the sqrt function.
import 'dart:math' as math;

// Create a class for Point.
class Point {

  // Final variables cannot be changed once they are assigned.
  // Create two instance variables.
  final num x, y;

  // A constructor, with syntactic sugar for setting instance variables.
  Point(this.x, this.y);

  // A named constructor with an initializer list.
  Point.origin()
      : x = 0,
        y = 0;

  // A method.
  num distanceTo(Point other) {
    var dx = x - other.x;
    var dy = y - other.y;
    return math.sqrt(dx * dx + dy * dy);
  }

  // Example of Operator Overloading
  Point operator +(Point other) => new Point(x + other.x, y + other.y);
}

// All Dart programs start with main().
void main() {
  // Instantiate point objects.
  var p1 = new Point(10, 10);
  var p2 = new Point.origin();
  var distance = p1.distanceTo(p2);
  print(distance);
}
