Solved How to detect an advancement.

Hey, I am making a plugin that detects when an advancement is given.

My question is how to do you get the name of an advancement so you can detect it using the PlayerAdvancementDoneEvent, this is my code so far:

Code (Java):

 @EventHandler
    public void onAch(PlayerAdvancementDoneEvent event){
        Player player = (Player) event.getPlayer();
        User user = User.get(player);
        Advancement advancement = event.getAdvancement();
        String name = advancement.getKey().getKey();
        if(name.equalsIgnoreCase("minecraft:end/dragon_breath")) {
            if(user.getFile().get("ADVMINT") == true) {
                return;
            }

            user.getFile().set("ADVMINT", true);
            user.getFile().set("ChallengesComp", user.getFile().getInt("ChallengesComp") + 1);
            user.saveFile();

            Bukkit.broadcastMessage("§8[§bChallenges§8]: §b" + player.getName() + " §fCompleted the §bDragon Hunter §fchallenge.");
            player.sendMessage("§8§m-----------------------------------------");
            player.sendMessage("§a§lCONGRATS!");
            player.sendMessage("§fYou completed the §bDragon Hunter §fchallenge.");
            player.sendMessage("§fYou have completed §b" + user.getFile().getInt("ChallengesComp") + "§8/§b11 §fchallenges.");
            player.sendMessage("§8§m-----------------------------------------");
        }
    }
 

 

I already fixed it, thanks for helping.
