dart set final variable in constructor

Professional Googler on May 28, 2020

// You cannot mutate final variables in a constructor body, 
// instead you must use a special syntax.
// Also note if you have a super() call, it must be called last.
class Point {
  final num x;
  final num y;
  final num distanceFromOrigin;

  // Special syntax
  Point(this.x, this.y) :
    distanceFromOrigin = sqrt(pow(x, 2) + pow(y, 2));
}
