Hey man! Thanks for the awesome content!

I'm getting this error:

_CastError (Null check operator used on a null value)

The error is related to the "currentState!" on the "if" line off following function:

void openCloseSideMenu() {
if {

}
else
{

}
}

I've just cloned your repo to see if I got what's wrong but even your code is getting this. Could you give me some direction to fix it?

Thanks a lot!
