operator == method
Overrides the equality operator (==) to compare this AffinePointt instance
with another object. It returns true if the other object is also an
AffinePointt and if the curve, x, and y coordinates match.
Implementation
@override
bool operator ==(Object other) {
if (other is AffinePointt) {
return curve == other.curve && x == other.x && y == other.y;
}
return other == this;
}
