# squaredDistanceTo method Null safety

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.

## Implementation

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