How do the states of true and false obtained in the check box @ click in vue be passed to another function under mothods?

I added a click event to the check box

what I need now is that I am in the next function

 drawLine(){
        console.log(this.ceshi());
   }

when I click on the check box, I can"t get the status of status at this time. How can I get it? as soon as ceshi changes my function below, I have to listen

@change="ceshi($event)" //change

ceshi(event){
    //event.target.value
}

@click="drawLine(ceshi())"


drawLine(status){
        console.log(status);
}
