A Point is only equal to another Point with the same coordinates.
This point is equal to other if, and only if, other is a Point with x equal to other.x and y equal to other.y.
bool operator ==(dynamic other) =>
// Cannot change parameter type to `Object` in case some class
// inherits the type and uses their argument dynamically.
other is Point && x == other.x && y == other.y;
