        toaster.setMessage('Username '+this.newuser.displayName+ ' already exists');
        toaster.present();
        console.log('user exist'); //it works till here 
      }
      else{
        console.log('user does not exist'); //but it never displays this if above statement is wrong it 
      //simply doesn't display anything. some times it works. sometimes it does not work at all.
      }
