# squaredDistanceTo method

T squaredDistanceTo(

1. Point<T> other

)

Returns the squared distance between `this` and `other`.

Squared distances can be used for comparisons when the actual value is not required.

Example:

    var squaredDistance =
        const Point(0, 0).squaredDistanceTo(const Point(0, 0)); // 0.0
    squaredDistance =
        const Point(0, 0).squaredDistanceTo(const Point(10, 0)); // 100
    squaredDistance =
        const Point(0, 0).squaredDistanceTo(const Point(0, -10)); // 100
    squaredDistance =
        const Point(-10, 0).squaredDistanceTo(const Point(100, 0)); // 12100

## Implementation

    T squaredDistanceTo(Point<T> other) {
      var dx = x - other.x;
      var dy = y - other.y;
      return (dx * dx + dy * dy) as T;
    }
